Review of ICRP-60: Implications for radioactive waste management.

摘要

Radiation exposure has generally been managed based on exposure or dose limits. These limits have undergone revisions every decade or so as further information on the biological effects of various types of radiation become available. For example, in the early 1950's for workers, a whole body dose limit of 3 mSv (0.3 rem) per week was being used in the United States until 1957 when the National council on Radiation Protection and Measurements, (NCRP) recommended a limit of 50 mSv (5 rem) per year. Currently, the US Nuclear Regulatory Commission (NRC) specifies a whole body limit of 1.25 rem per calendar quarter (5 rem/y)(10CFR 20).
