Advisory Committee on Human Radiation Experiments COLLECTIONS AND INDEXES ACHRE has assembled an enormous collection of records and secondary sources documenting the basic activities and issues in the history of federal government involvement in human radiation experiments. The Advisory Committee's collection is the only repository of substantive documentation from all the government agencies involved and from outside the government, and is thus the broadest source of information for the citizen starting his or her own research. The ACHRE collection will be deposited essentially intact in the National Archives, including (to the extent feasible) the electronic finding aids. ACHRE has constructed several indexes to its collection, the primary ones being databases controlling the document collection, the publication collection, and information on experiments. The indexing in these collections has relied on some basic reference thesauri, and these are included in this gopher under Terms and References. Experiments are indexed by principal investigator, location, sponsor, and date, but are given only brief descriptions that do not include the more detailed information (for example, radiation used or subject consent) included in the database. Similarly, the research document collection is represented by brief content descriptions that contain only summary information--none of the collection inventories or descriptions of individual documents that are part of that database are included. On the other hand, the publications collection is essentially a standard bibliography, and its entries contain all the information recorded in that database..
