The records of radiation control division, no.29 (1993)

This report summarizes activities of the Radiation Control Division of KURRI in FY 1993 (from 1 April, 1993 to 31 March, 1994). The Division consists of three Sections: Indoor Radiation Control, Field Radiation Monitoring and Personnel Monitoring Section. Now 18 members including research scientists and technicians are assigned as staffs of the Division, while two persons were reshuffled to the other universities and a new figure was welcomed in this year. The results of activities of the Indoor Radiation Control Section show that levels of external radiation and radioactive contamination within the controlled area have mostly cleared legal criteria, and that management of radioactive isotopes has been dealt with in strict fairness. The Field Radiation Monitoring Section did not detect any unusual level of radiation in the environment. The Personnel Monitoring Section affirms that no one has been exposed with more than 4mSv among 138 staffs and 21 students and researchers. The report also describes tasks exercised by the Office of Health Physics including safety education for staffs and visitors, and liaison with the governmental offices. (author)
