In March, 1954, the Com- “mander, Joint Task Force SEVEN, authorized higher limits of ex- posure for several types of work, establishing different limits for different classifications. _ -| eyf° In actual practice, it was deokied - that film badges would be turned in to the Rad-Safe group, who would evaluate the film and notify holders of badges of their accumulated exposures. This procedure, plus notification by Rad-Safe to TG 7.5 management whenever an individual had reached an accumu- lation of radiation equal to 2.5r, was considered to provide assurance that none of TG 7.5 personnel would be exposed beyond allowable limits.
