Series Description: This record series consists of reports, in the form of memoranda, describing the routine health physics activities in building 706-C, where many radionuclides were produced for commercial, medical, and industrial use. Information on levels of radioactivity is expressed in milliroentgens/hour (mr/hr), roentgens/hour (r/hr), and counts per minute (c/m). The reports describe in detail spills and leaks of radioactive materials and cleanup procedures, as well as individual employee exposures and incidents. Employee exposure levels are reported in r/hr. Iodine-131 measurements are provided in curies. Reports are issued at irregular intervals, generally every one to three weeks.

Data Elements: 8, 31, 62, 77, 91, 102, 122
