Bugher, Director Dear Dr. Bugher: SUBJECT: \ CRI -PARTITE CONFERENCE ON PERMISSIBLE DOSES Ne For the subject conference, I would like to present our data on the permissible concentration of plutonium in driniing water, and on the discrepancy between the permissible limit for ti3l compared with vegetation contamination. in the atmosphere , Presumably there will be a discussion of the tritium hazard. In this field, too, Hanford has a significant body of relatively new information. Same of the principal matters that we would like to hear discussed, without significant contribution from us are: (1) Policy on planned emergency exposures. (2) The number of weeks over which exposure may be reasonably (3) The genetic effect. (4) Permissible limits for persons not occupationally exposed. (5) Permissible limits for life forms other than man. (6) Progress on the problem of relationship between radium content averaged. of drinking water and incidence of bone lesions.
