DISCLAIMER The following is a staff memorandum or other working document prepared for the members of the Advisory Committee on Human Radiation Experiments. It should not be construed as representing the final conclusions of fact or interpretation of the issues. All staff memoranda are subject to revision based on further information and analysis. For conclusions and recommendations of the Advisory Committee, readers are advised to consult the Final Report to be published in 1995. TO: Members of the Advisory Committee on Human Radiation Experiments FROM: Advisory Committee Staff DATE: June 29, 1994 RE: Documentation of Intentional Releases We have previously provided documentation on the Green Run experiment. This tab contains further documentation of intentional releases of radiation. It appears that the intentional release category is broader than the experiments enumerated in the Committee charter. If defined strictly in terms of the intentional release of radioactivity into the environment, the category is quite broad. For example, Stannard devlotes a large section of his work to chapters entitled "Survey of Radioecology: Environmental Studies Around Production Sites," "Biomedical Research Stimulated by the Problems of Fallout," and "Special Environmental Test Projects." What is not clear is (a) the extent to which intentional releases were performed with an intent to study effects on human beings, and (b) the extent to which, if humans were not the express object of study, significant human exposures may have nonetheless occurred. Attachment 1 The "Overview" sections from the three Stannard chapters noted above. Attachment 2. The Markey report notes, at 22, that from 1963 to 1965 "radioactive iodine was released intentionally on seven separate occasions." Attachment 2 is Dr. Stannard's write-up of the "Controlled Environmental Radioiodine Tests". Attachment 3. the Stannard interviews provide a flavor for intentional-release activity. In his interview, Stafford Warren refers to the contamination of an alfalfa field in Rochester, in order to take measurements on radiosodium (See Tab E-2, Warren interview transcript at 3). This episode appears to be described at greater length in the attached transcript of the interview of Dr. H. C. Hodge. We also attach an excerpt from the interview of David Bruner, an Atomic Energy Commission/Energy Research and Development Administration/Department of Energy official, which summarizes the development of "outdoor laboratories." Attachment 4. Letter from Jimmy C. Massey to Jimmie C. Hodges; Report on DOE's Oak Ridge search revealed evidence of "deliberate experimental releases of UF6 to the atmosphere in 1955 and again in 1974." Attachment 5. DOE's Oak Ridge search also provided some documentation of the 1948 Radiological Warfare program, including an intentional release(s). This attachment contains: a. June 29, 1948 memo to K.Z. Morgan from J.H. Roberson regarding "Radiological Warfare Program." The memo refers to "two experiments...requested by Murphy." b. A July 2, 1948 memo to J.C. Franklin from Walter J. Williams regarding "Radiological Warfare Program." c. A July 14, 1948 memo from J. Roberson to K.Z. Morgan regarding "AHRUU Project," and a further memo from K.Z. Morgan and C.N. Rucker on the results of an AHRUU program experiment. Attachment 6. As in the case of other experiments, intentional release/environmental experiments were often contemporaneously reported in professional journals or other research reports. We attach an abstract referring to "massive gamma radiation which killed part of" the El Verde Rain Forest in Puerto Rico. Attachment 7. Dr. Stannard's book contains a description of the "subtle" approach employed to get environmental data from the public without divulging the purpose of the data collection. The example does not appear to relate to an intentional release.
