  DESCRIPTION  These files document the founding of the Los 
               Alamos National Laboratory and its  subsequent 
               work to develop fission bombs for use in WWII. 
               These files contain some  information on the 
               biological effects of uranium-235 and 
               plutonium-240, the earliest  known references to 
               the possibility of human experimentation by the 
               Manhattan  Engineer District, and the creation of 
               RaLa Testing Program. These records were  compiled 
               by the Laboratory during WWII as the primary 
               documentation of the Laboratories' wartime 
               activities. As such they document technical, 
               administrative, and policy  decisions related to 
               the development of the first nuclear bombs. The 
               Project Y files  consist of technical and 
               administrative files of memorandums, letters, and 
               reports.  They are organized by major 
               organizational units of the Laboratory. A folder 
               title listing  is available. Collection number A 
               84 019.
