Purpose

(A) 105 CMR 120.200 establishes standards for protection against ionizing radiation resulting from activities conducted pursuant to licenses or registrations issued by the Agency. The requirements of 105 CMR 120.200 are designed to control the receipt, possession, use, transfer, and disposal of sources of radiation by any licensee or registrant so the total dose to an individual, including doses resulting from all sources of radiation other than background radiation, does not exceed the standards for protection against radiation prescribed in 105 CMR 120.200. However, nothing in 105 CMR 120.200 shall be construed as limiting actions that may be necessary to protect health and safety. (B) 105 CMR 120.200 is issued pursuant to M.G.L. c. 111, §§ 3, 5M, 5N, 5O, 5P.
