105 CMR 120.210
Radiation Protection Programs
(A) Each licensee or registrant shall develop, document, and implement a radiation protection
program sufficient to ensure compliance with the provisions of 105 CMR 120.200. See
105 CMR 120.262 for recordkeeping requirements relating to these programs.
(B) The licensee or registrant shall use, to the extent practical, procedures and engineering
controls based upon sound radiation protection principles to achieve occupational doses and
doses to members of the public that are as low as is reasonably achievable (ALARA).
(C) The licensee or registrant shall, at intervals not to exceed 12 months, review the radiation
protection program content and implementation.
(D) To implement the ALARA requirements of 105 CMR 120.210(B), and notwithstanding
the requirements in 105 CMR 120.221, a constraint on air emissions of radioactive material to
the environment, excluding Radon-222 and its daughters, shall be established by licensees, such
that the individual member of the public likely to receive the highest dose will not be expected
to receive a total effective dose equivalent in excess of 0.1 mSv (ten mrem) per year from these
emissions. If a licensee subject to this requirement exceeds this dose constraint, the licensee
shall report the exceedance as provided in 105 CMR 120.283 and promptly take appropriate
corrective action to ensure against recurrence.
