|(a) Each licensee shall develop, document, and implement a radiation protection program commensurate with the scope and extent of licensed activities and sufficient to ensure compliance with the provisions of this subchapter. See §336.342 of this title (relating to Records of Radiation Protection Programs) for requirements for maintaining records relating to these programs. (b) The licensee shall use, to the extent practicable, 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 shall, at intervals not to exceed 12 months, review the radiation protection program content and implementation. (d) To implement the ALARA requirement of subsection (b) of this section, and notwithstanding the requirements in §336.313 of this title (relating to
Dose Limits for Individual Members of the Public), a constraint on air emissions of radioactive material to the environment, excluding Radon-222 and its daughters, shall be established by licensees other than nuclear power reactors, 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 10 mrem (0.1 mSv) per year from these emissions. If a licensee subject to this requirement exceeds this dose constraint, the licensee shall report the exceedence as provided in §336.352 of this title (relating to Reports of Exposures, Radiation Levels, and Concentrations of Radioactive Material Exceeding the Limits) and promptly take appropriate corrective action to ensure against recurrence.
