Email: cnd@gn.apc.org CND 24 hour Membership and Donation Hotline: 0171 700 2352 CND Home Page: http://www.mcb.net/cnd Summary 1.1 The Campaign for Nuclear Disarmament has uncovered documents which show that for over 30 years the British and American governments have deliberately covered up a serious nuclear accident at the US Air Force base Greenham Common, best remembered for the controversial stationing of Cruise missiles there and the protests which followed. The accident put at risk the lives of hundreds of thousands of US and British service personnel, civilians working on the base, local residents, peace campaigners, police officers and journalists. Local land and animals were contaminated, but no clean up operation has ever been mounted. The radioactive dust from the accident continues to pose a serious threat to the local environment and the health of local residents in an area renowned for an unexplained cancer cluster. 1.2 The accident happened in 1958 when an American B-47 nuclear bomber - loaded with its nuclear weapon - caught fire. The bomb burnt, releasing deadly uranium and plutonium oxide powder over an area of several miles around the base. Plutonium and uranium particles are lethal when ingested or inhaled. The conventional explosive in the warhead exploded, helping to scatter very fine uranium and plutonium particles. 1.3 The accident was discovered almost by chance by a team of scientists at the Government's atomic weapons research establishment at Aldermaston. The discovery prompted a full investigation by a team of up to 60 Government nuclear scientists, whose findings were written up in a secret report, parts of which have been obtained by CND. The report details the scientists' findings, including a map of the spread of contamination from the accident around West Berkshire and North Hampshire. CND has also obtained secret letters written during the investigation, and has learnt about other official Government investigations which have confirmed that a nuclear accident did indeed take place at Greenham common. 1.4 Today, the accident poses a very serious threat to people's health and the environment. As recently as 1994 a follow-up survey by Aldermaston scientists of the area detected contaminated fall-out from the 1958 accident. A total of between 10-20g of uranium was released and dispersed outside the base, yet no clean-up operation has ever been mounted. A much greater amount of plutonium and uranium was certainly deposited inside the base itself on and around the runway - the warhead involved contained about 20kg of plutonium and 30-40kg of enriched uranium - yet the contaminated runway has been crushed and now stands in piles blowing dust over the surrounding area, with some reports suggesting that it will be used in the Newbury by-pass. An industrial estate and now a night club have just opened near the site of the accident. 1.5 Over the years, radioactive dust has been repeatedly disturbed and blown over the area by jet aircraft taking off and landing on the contaminated runway. Hundreds of thousands of people stood next to the runway whilst aircraft took off and landed during the famous Air Shows and International Air Tattoos held at Greenham Common between 1970 and 1983. Tens of thousands of British and American service and civilian personnel were stationed on the base whilst it was on active service. Large amounts of contaminated dust were then raised during major reconstruction work at Greenham Common prior to its becoming a base for Cruise missiles and, more recently, the demolition of the contaminated runway after the base's closure. 1.6 Particles of alpha-emitting uranium and plutonium are extremely dangerous if swallowed or breathed in. Plutonium, for example, causes fatal cancer if just a tiny amount - as little as 15% of 80 5g of plutonium particles - taken into the lung remains there. It can also kill if taken in as food. The effects of uranium are similar, and uranium can - in addition - cause a form of heavy metal poisoning. Plutonium has a radioactive half-life of 24,000 years, while the half life of uranium-235 is 710 million years. To all intents and purposes, therefore, the whole area for miles around Greenham Common has been permanently contaminated. A report by American Government scientists from that era, which depicts a hypothetical scenario almost identical to events at Greenham Common, recommends permanent evacuation of the base and nearby residential areas. 1.7 The total numbers of people potentially affected are huge. Hundreds of thousands of people served at or visited Greenham Common whilst it was an active airbase. The concentrations of contamination in the surrounding area are highest in the built-up areas of Newbury and Thatcham. A host of villages and small towns stretching from as far apart as from Kintbury in the West, Watership Down and Kingsclere in the South, Heath End and Stafford Dingley in the East, and Hermitage and Welford in the North have also been covered by radioactive dust. Many more thousands of peace campaigners, police officers and journalists attending the huge protests against Cruise missiles around the base's perimeter during the 1980s may also be at risk. 1.8 There is a well-known cancer cluster in the area, and official government studies have confirmed an unusually high incidence of radiation-linked cancer among children living in the area. The accusing finger has been pointed at the atomic weapons research establishments at Aldermaston and Burghfield, but detailed studies have been unable to find a link between these establishments and cancer among local children. However, the Government's inquiry into the clusters, conducted by COMARE - the Committee on Medical aspects of Radiation in the Environment - was not told by the government about the amounts of radioactive dust known to have been released into the area around these clusters by the accident at Greenham Common. One local school - which has since closed - was located at the eastern end of the runway, and is at the centre of the highest radioactive hotspot found by Government scientists. 1.9 Documents concerning the accident and which illustrate the extent of contamination - including some which CND has been unable to obtain - remain closely-guarded secrets. CND is calling for all files relating to the accident to be opened, for a Public Inquiry to investigate why the Government has covered up the accident, for free health checks to be made available to anyone who believes they may have been contaminated, for the COMARE investigation into local cancer clusters to be re-opened, and for a clean-up operation to dispose of the crushed runway and minimise the impact of radiation in the local environment, including crops and animals reared for food. 2. Part A The Accident 2.1 In May 1960 a group of scientists working at the atomic weapons research establishment (AWRE) at Aldermaston found highly radioactive readings near the atomic weapons research establishment where that could not possibly be explained by its emissions. They used readings taken from laurel leaves, which are highly accurate indicators of uranium contamination, and discovered that the amount of uranium-235 to the west of Aldermaston was one hundred times greater than could be accounted for by AWRE's discharges. 2.2 When plotted, their readings showed hourglass-shaped contours of radioactive contamination centring around the runway at Greenham common, which at the time was the base for US Air Force B-47 bombers on constant "Reflex Alert", loaded with nuclear bombs and ready to fly to the Soviet Union at a few minutes notice. 2.3 The findings were written up in a secret report called "The distribution of uranium-235 and plutonium-239 around the USAF base, Greenham Common, Berkshire" and submitted in August 1961 to Sir William Penney, the head of the UK Atomic Energy Authority (UKAEA) and one of the architects of the British nuclear bomb programme. around 50 to 60 scientists from both Harwell and Aldermaston were involved in compiling this report. The research team was led by R Morgan, a radiochemist from Aldermaston. The report carries no AWRE or UKAEA report reference number and is not in any of standard classified reports series produced by Harwell and Aldermaston. however, the Government has recently confirmed the existence of this report and told Parliament that its contents would remain secret [ref 1]. 2.4 Attached to the report is a map of the area, complete with ordnance survey grid references, showing two regions of radioactive contamination extending east and west of the base, with a narrow waist at the airfield. The readings are plotted out as far as 8 miles around the base, covering the built-up areas of Newbury, Thatcham and Kingsclere, and including centres of population as far apart as Kintbury in the west, Aldermaston in the east, and stretching from Hermitage in the north down to Watership Down in the south. Newbury and Thatcham are at the centre of the two worst hotspots east and west of the airfield. 2.5 The report states clearly that the quantities involved and the wide dispersal are such that "the release must have been accidental. Further, in order to release 10-20g of finely dispersed uranium, much larger amounts must have been involved in the accident and it seems that the only possible way such that a large quantity could become powdered is through the agency of fire, or an explosion". 2.6 It blames an accident which took place at Greenham Common at 4.25pm on February 28, 1958 but which it has always been officially denied involved a nuclear weapon. An aircraft awaiting take-off on the runway was engulfed in a fireball when a wing-tip tank carrying 1,700 gallons of fuel from another B-47 flying overhead was accidentally dropped. The fuel tank landed just 65 feet behind the parked B-47 and directly in line with it, igniting on impact and engulfing the plane. Hangar Number 1 was also severely damaged, and other planes nearby had to be hosed down for fear that they too might ignite. Photographs from the accident are still classified secret. 2.7 B-47s from 3909th Combat Support Group (SAC) at Greenham Common, which included the 310th Bomb Wing, carried Mark V and MarkVI nuclear bombs. These had a nuclear yield of up to 60 kilotons. each warhead had a plutonium core of around 20kg, surrounded by about 30-40kg of enriched uranium and TNT-type High Explosive (HE). the enriched uranium was used to increase the bomb's yield by a few tens of kilotons. In the event of fire or explosion both the enriched uranium and plutonium would be released in the form of a fine and deadly oxide powder. 2.8 Because of their high magnesium content both the aircraft and its payload burnt extremely vigorously. In fact the aircraft was simply allowed to burn out because it was impossible to extinguish the magnesium. The fire was still smouldering five days later, the heat reached temperatures as high as 1,000 degrees Celsius, explosions could be heard for miles around, and local firemen at first believed that there had been an atomic explosion at the base. A man underneath the aircraft at the time - who may have been involved in the bomb's loading procedure - was burnt to death. A number of other service personnel were killed and injured in the accident. A Board of officers was appointed to investigate the accident. It's findings are still secret. It is not known what happened to the wreckage of the plane or the bomb. 2.9 The base commander, Colonel Arthur Cresswell, denied that the B-47 which was destroyed was carrying a nuclear weapon at the time [ref 2] in fact, it emerged in 1979 that the British and American governments had agreed in 1956 to deny that nuclear weapons were present in any accident involving American nuclear bombers stationed in the UK. The agreement surfaced after details of another crash involving a USAF B-47 - which crashed into a nuclear bomb storage bunker at RAF Lakenheath in 1956 - were revealed by an American newspaper with close links to the US Air Force. According to a former US Strategic Air Command officer, orders came down to keep 'nukes' out of the records. Officially they did not exist. When somebody asked why people fled the base we told them that it was because there was live .50 calibre ammunition in the airplane [ref 3]. It is also now known that during that month, B-47s at Greenham Common were involved in an exercise called 'Rough Game'. A secret unit Group diary - obtained by CND - reveals that the exercise was testing 310th Bomb Wing's emergency war plan. American bombing exercises in Britain commonly carried live nuclear weapons, even when they were flying over London [ref 4]. 2.10 The report by Aldermaston's scientists directly disputes the American base commander's statement: "We suggest that, in fact, a nuclear weapon may have been carried in the aircraft and burned with it." The UK Government's statement to the House of Commons at the time confirmed that a parked B-47 had burned, but does not mention whether or not a nuclear weapon was on board [ref 5]. Strangely, the Government went back on its own version of events some years later, stating that the accident had merely involved a parked B-47 being hit by a taxying B-47 on a training exercise, and omitting any mention of a fire [ref 6]. The American Government - which has published details of a few accidents involving its nuclear weapons has never admitted that the accident at Greenham Common involved a nuclear bomb. However, a journalist for an investigative American magazine has been told by Pentagon officials that there are "less than ten" nuclear weapon accidents of which details would not be released for political and national security reasons [ref 7]. 2.11 Radioactive debris from the bomb was stuck to Greenham Common's runway by the firefighters' foam. However, the scientists found that the contaminated debris has been repeatedly disturbed by vehicle and aircraft movements and jet blast wearing away the runway surface and causing radioactive dust to be blown out of the base into the surrounding countryside. In particular, the report warns about the danger of continuing to use the runway because "the high temperature of the air from the jets would cause it to rise, carrying dust and sand particles up with it". The hourglass shaped concentrations of radiation materialized because Greenham Common has just one runway with two take-off directions. 2.12 The covering letter - dated August 11, 1961 - sent to Sir William Penney and stapled to the front of the report reveals that the British intelligence services were almost certainly aware that an accident had taken place: "In the report, we have quoted only official statements, but other information from Group security officer lends credibility to the sequence postulated viz a fire in a loaded B-47, runway contamination, dispersion by normal aircraft movements" The 'Group security officer' referred to would have been an intelligence officer at Aldermaston. The letter - which is marked confidential - acknowledges the enormous political implications of the report's contents: "Because of the sensitivity of the report, six copies only have been prepared". Other documents related to nuclear weapons accidents are still secret, even though they are all over 30 years old. Files listed in the Public Records Office under the heading Nuclear Weapons Hazards from an aircraft crash for 1957 and 1958 are classified, as is a file entitled Appointment of Weapon Accident Investigation Team' (1958-64). 2.13 In 1987, after the signing of the Intermediate Nuclear Forces (INF) Treaty which scrapped Cruise missiles, Aldermaston did a detailed follow-up survey of contamination around the site. The new study was written up by W N Saxby, a Technical Staff Officer from Aldermaston's Safety Division, and an experienced scientist who had been involved in monitoring fall-out from Britain's atmospheric atomic tests in the South Pacific. Saxby's report confirmed that a nuclear accident had taken place at Greenham Common and found the same hour-glass shaped deposits of contamination around the runway that were found in the first report of 1961. The Saxby report is classified secret, and after its findings were made known within the Ministry of Defence the classification status of the original 1961 report was reviewed and significantly upgraded to "SECRET UK EYES 'A' NAMED AWE DISTRIBUTION ONLY". 2.14 In 1994 there was yet another survey of contamination around Greenham Common by scientists from Aldermaston. For the first time, readings were also taken from inside the base itself. The study detected the same radioactive contours found in both the 1961 and 1987 studies. However, like the 1961 and 1987 reports, it is also classified secret. Shortly afterwards, the Defence Radiological Protection Service (DRPS) carried out an 'official' survey for the Government, which the Government then used to deny showed that "Greenham contains any nuclear contamination attributable to its former military use", adding that "the levels of radioactivity present were similar to those prevailing throughout the UK" [ref 8]. Nevertheless, the DRPS survey has also not been made public. 2.15 More than a million tons of concrete from Greenham Common's runway have now been dug up and crushed, and currently stand in uncovered piles of dust. There are reports that the crushed concrete could now be reconstituted and used in the foundations of the controversial Newbury by-pass [ref 9]. Most of the buildings on the base are now let as industrial units, and in June of this year a new all-night dance club and live music venue opened just a few hundred yards from the old Cruise missile silos. The Sports Council also hopes to open a new leisure centre on the base with the help of national lottery cash [ref 10]. 3. Part B The Health and Environmental Effects 3.1 Tens of thousands of American and British personnel and civilians have served at Greenham Common since the late 1950s. hundreds of thousands of people have visited the base and stood by the contaminated runway watching aircraft take off and land as spectators at the Air Shows held at Greenham Common between 1970 and 1983. There are upwards of 150,000 people now living in the areas marked out by the 'radiation map attached to the 1961 report. There are a number of boarding schools in the area, including Crookham Court which has now closed but which is located almost at the end of Greenham's runway and at the centre of the main radioactive 'hotspot to the east of Greenham. During the 1980s, Greenham Common saw protests by hundreds of thousands of people which were policed by officers from several forces and reported by journalists from all around the world. 3.2 There have been persistent reports of unusually high and radiation-linked cancers in the area. These were first revealed in letters to 'The Lancet', a medical journal, in November 1985 and February 1986. The first letter stated that "since the establishment of a paediatric oncology/haematology clinic at the Royal Berkshire Hospital, Reading, in 1971 we have been concerned that we were seeing more children with acute leukaemia than might be expected in a population the size of our health district's [ref 11]. The claims also became the subject of a TV documentary. The documentary, 'Inside Britain's Bomb' [ref 12], examined the incidence of leukaemia in the nine rural local authority wards in two circles of around 4km around Aldermaston and Burghfield. The reports all suggested a link between the unusually high incidence of leukaemia among local children and the atomic weapons research establishments at Aldermaston and Burghfield. 3.3 In 1989, the Government appointed its Committee on Medical aspects of Radiation in the Environment (COMARE) to investigate the claims, and specifically to establish whether there was any link between the cancer clusters and Aldermaston and Burghfield. COMARE concluded that there was a 'small but statistically significant' increase in the number of cancers that would be expected among young children in the area. However, it was unable to find any link between its findings and emissions from either Aldermaston or Burghfield. Greenham Common was not included in the COMARE study, even though the Government knew that the spread of radiation recorded in the 1961 study covered much of the area looked into by COMARE. Other areas covered with contaminated dust by the Greenham Common accident were excluded from the COMARE survey. The Ministry of Defence did not tell COMARE's research team about the accident at Greenham Common, and did not pass them either the original 1961 report or the 1987 Saxby report. 3.4 The findings of the 1961 and 1987 Aldermaston reports could provide the missing link COMARE was looking for. They clearly detail the dispersal of significant amounts of uranium and plutonium, both of which emit alpha radiation and produce extremely toxic effects inside the body if inhaled or ingested. A lung deposit of alpha-emitting particles can track through the body, settling in the liver and bone structure, and destroy the bone marrow's ability to create infection-fighting white blood cells. the inhalation of plutonium particles can cause cancer of the lung and in other parts of the body if carried in the bloodstream. uranium produces very similar radiological hazards as plutonium and can in addition cause a type of heavy-metal poisoning. 3.5 It has now emerged that the American Government in the 1950s was clearly aware of the potential health and environmental hazards of an nuclear weapons accident of the type which subsequently occurred at Greenham Common. A recently declassified study by the US nuclear laboratory at Los Alamos in 1955 [ref 13] concludes that "the problem of decontaminating the site of the accident may be insurmountable and it may have to be 'written off". It added that families living nearby would have to be permanently evacuated and individuals forbidden from ever working there again. In a long list of short and long-term health and environmental hazards, it specifically expresses concerns about the risks posed to those involved in clean-up operations and "persons entering and working in the area, performing operations that produce considerable dust." 3.6 There is now direct evidence that those involved in fire-fighting or a clean-up operation following a nuclear weapons accident are at enormous risk. Following an accident at Thule in Greenland in 1968, when a B-52 carrying nuclear bombs crashed, official reports claimed that radioactive contamination from the accident was "minimal" [ref 14]. Twenty years later, however, it was discovered that of the 800 Danes involved in the clean-up operation, more than 500 had fallen ill, nearly 100 of whom had cancer and "an unknown number of the same group of workers are said to have died as a result of exposure to plutonium released in the accident" [ref 15]. No follow-up study of those involved in fighting the fire at Greenham Common has ever been done. 3.7 Animals grazing in the area may also have been contaminated by the Greenham Common accident. Animals can absorb plutonium by inhaling resuspended particles - in other words, radioactive dust that is disturbed. The primary intake for herbivores is likely to be through food. This can then be passed upwards through the food chain. Plutonium can both be absorbed into soil and absorbed by micro-organisms, and also dispersed into the air in airborne spores. The area around Greenham Common contains a deep groundwater system which is part of the major aquifer for South East England, and it is possible that contamination will have reached the shallow groundwater system and the chalk aquifer. 4. Conclusions 4.1 In January 1958, the Daily Telegraph reported that the American Government had confirmed that a plane carrying an atomic bomb had crashed in the US and that radioactive material had been scattered in the countryside by the fire which followed. The newspaper called for information about the accident to be passed onto British scientists to help them understand the effects of oxidised plutonium and uranium, adding that "naturally such a crash would be more dangerous here than in the US, for a greater proportion of our surface area either produces crops or is densely populated" [ref 16]. There was considerable concern in the late 1950s about the possible consequences of an accident of precisely the kind which actually took place at Greenham Common. With increasing public concern about the nuclear threat, the launching of CND and the recent arrival of US nuclear bombers in Britain, the publicity which would have accompanied knowledge of the Greenham Common accident would have threatened the US presence in the UK altogether. It would also have threatened the development of the British bomb, still in its relative infancy. 4.2 The Government has previously stated that 'there has never been an accident involving damage to, or release of radioactivity from a nuclear weapon in the United Kingdom" [ref 17]. This report shows that this is patently untrue, and that the Government knows this to be untrue. The Government must publicly admit this. The US government has been similarly dishonest. When the British government was asked by an MP whether there had been "any accidents involving US Air Force aircraft carrying nuclear weapons in the UK and whether any such accident had resulted in the release into the atmosphere, into water or into the ground of radioactive materials", the House of Commons was told: "The US authorities have confirmed that there have been no such accidents involving US Air Force aircraft [ref 18]. 4.3 Plutonium has a radioactive half-life of 24,000 years, and uranium 235 of 710 million years. The contamination of Greenham Common and of the air, soil, food and water of the surrounding area will be in evidence for generations to come. The potentially devastating effects of alpha-emitting plutonium and uranium on humans, animals and the environment are well known. A now declassified US Government report from 1955 shows that the American government's own nuclear experts believed that in an accident like this the base should have been closed down and the area cordoned off forever. The repeated disturbance of the runway through its continuous use, reconstruction work in 1980s and the demolition work of recent months has raised and spread more radioactive dust over the area time and time again, and placed those in closest contact with the dust at particular risk. The runway now stands in piles of dust - known locally as 'the Alps of Berkshire' blowing yet more dust over Newbury and nearby areas. 4.4 It is extraordinary and nothing short of scandalous that evidence about the accident and local contamination in the possession of the Government should not have been passed to those appointed by it to explore links between radiation and cancer suffered by young children in the area. It is hardly surprising that the COMARE report was inconclusive when vital evidence was withheld from it and which could have provided the missing link between local radiation emissions and leukaemia clusters in the area. 5. Recommendations 5.1 All readings ever taken by Aldermaston and the Defence Radiological Protection Service must be made public without delay, and all files relating to nuclear weapons accidents and investigations - including Board of Inquiry reports - should be released for publication. 5.2 The British Government must demand from the American Government all evidence and information about the fires and accidents of 1957 and 1958, including base logbooks and readings taken for uranium and plutonium inside the base, and place it in the public domain. 5.3 There must be a full and open Public Inquiry into the accident, the circumstances surrounding it and the effects on the local area and local populations, including an investigation into the Government's repeated failure to pass on evidence about contamination to Parliament and the Government's own Committee on the Medical Aspects of Radiation in the Environment. 5.4 The immediate area of Greenham Common should be vacated and secured pending a full radiological survey undertaken by an agency independent of the Government, using detailed soil sampling techniques at regular intervals on and around the runway. 5.5 The Government must make available facilities for free health checks to all service personnel and civilians who have visited the base, or who have worked, lived or received education in the area, who currently work, live and receive education in the area, and who are concerned that they may have been contaminated by radioactive dust. 5.6 The crushed concrete from the runway must be covered, removed and disposed of immediately in order to prevent the continued dispersal of dust. 5.7 The Government must begin a clean-up operation to minimise the impact of radiation on local water tables, crops and animals reared for food. Any contaminated soil, vegetation or concrete must be removed and disposed of in a proper store for nuclear waste. 5.8 The COMARE report into cancer clusters in West Berkshire and North Hampshire should be reopened, and COMARE researchers should have access to all records and data on the Greenham Common accident.
