(a) Each person subject to this Part must minimize the disposal and release of radioactive material to the environment so that:

1. (1) the total effective dose equivalent to individual members of the public from the disposal or release does not exceed 0.1 rem (1 mSv) in a year, exclusive of the dose contributions from background radiation, from any medical administration the individual has received, from exposure to individuals administered radioactive material which have been released in accordance with a license, from voluntary participation in medical research programs, and from the licensee's disposal of material into sanitary sewerage in accordance with section 380-4.2 of this Part;
2. (2) the dose in any unrestricted area in the environment from external sources does not exceed 0.002 rem (0.02 mSv) in any one hour; and

3. (3) doses to individual members of the public are ALARA.

   (b) Constraint on airborne emissions.

   To implement the ALARA requirements of section 380-7.2 of this Part, and notwithstanding the requirements in this section, a constraint on airborne emissions of radioactive material to the environment, excluding radon-222 and its decay products, must be established by permittees 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 permittee subject to this requirement exceeds this dose constraint, the permittee must report the exceedance as provided in Subpart 380-9 of this Part and promptly take appropriate corrective action to ensure against recurrence.
