In the United States, the Nuclear Regulatory Commission (NRC) has the authority to enforce dose standards. Most states have entered into an agreement with the NRC to enforce the dose limits set forth by the NRC. In non agreement states, the NRC has jurisdiction.
Occupational Dose Limits - Limits established for those working in radiation areas
Annual dose limit to the whole body = 5 rem (50 mSv)
Annual dose limit for the eyes = 15 rem (150 mSv)
Annual dose limit for extremities = 50 rem (500 mSv)
Embryo-Fetus exposure in one month = 0.05 rem (0.5 mSv)
Embryo-Fetus exposure gestational limit = 0.5 rem (5 mSv)
Public Dose Limits - Limits established for the public areas which surround radiation areas
Public dose limit (annual) = 0.1 rem (5 mSv)
