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. STAFF MEMORANDUM TO: Members of the Advisory Committee on Human Radiation Experiments FROM: Advisory Committee Staff DATE: June 28, 1994 RE: Groupings of Experiments: A Methodological Overview In order to understand both the content and the context of the experiments uncovered, we are seeking a way to group experiments that will likely lead to efficient investigations and meaningful reporting of results. Each group would be anchored in at least one of the data points in the experimental template; for example, a group could be comprised of experiments with a uniform scientific or medical research purpose, or a uniform military purpose, or it might contain experiments performed by a single institution. The experiments in each group would likely differ in other respects; for example, experiments with uniform medical purposes may or may not have express government purpose, may have been sponsored by different agencies, and may have been governed by differing ethical codes and practices. Thus, by studying each grouping, and by viewing groups collectively, we may be able to view and understand experimentation from many angles of vision. It should be emphasized that the purpose is not to exclude experiments from study, but to place individual experiments into the larger context of the Committee's work. As groups are defined, it may be easier to identify the best ways to group (or sample) those experiments, including experiments identified in master lists provided by the agencies which have not been included in a group. 1 In this tab, we enclose documents that illustrate some groupings that we hope will lead to efficient investigation and meaningful reporting. The groups are: 1. Government Purpose. Here, as an example, we attach documentation of the research portfolio and program laid out in the 1949-1952 period by the Department Joint Panel on Medical Aspects of Atomic Warfare. (See Tab O-1) 2. Total Body Irradiation. This grouping, which might be called a grouping by research procedure, covers experiments conducted at dozens of sites, involving several thousand subjects, over many decades. (See Tab O-2) 3. Intentional Releases. As indicated in the attachment, this grouping includes not only the examples enumerated in the Committee's charter, but, perhaps, a broad variety of environmental releases. (See Tab O-3) 4. Radiological Warfare. While the extent of human experimentation remains to be seen, questions of secrecy, military purpose, and therapeutic purpose make this group an important and interesting one which may overlap with intentional releases. (See Tab O-4) These groupings are offered as examples. Other potential groupings might include: 1. Biodistribution Experiments: The plutonium injections and succeeding efforts to understand the metabolic and physiological effects of radioactive isotopes in the body, (i.e., based grouping). 2. Experiments of Opportunity: Experiments which were not intended at the onset, but in which the opportunity for study presented itself. (This grouping is presented as an analytical category, and not a judgement on scope.) 2 3. Therapeutic-purpose Experiments: a group, or series of subgroups, based on medical purpose. 4. Contemporary Experiments: a date-based grouping of experiments. 3
