Section 144-220-N-5 - Standards for radiation protection for TENORM

A. No person licensed under N.10 or N.11 shall conduct operations, use process, distribute or transfer TENORM in a manner such that a member of the general public will receive an annual TEDE in excess of 100 mrem (1 millisievert) per year from all licensed sources including TENORM.

C. Doses from inhalation of indoor radon and its short half-life (less than one hour) progeny shall not be included in calculations of the TEDE, unless specifically directed otherwise by the Agency. The Agency will provide its basis if it directs the inclusion of radon in such calculations.

D. No person shall release TENORM for unrestricted use in such a manner that the reasonably maximally exposed individual will receive an annual TEDE from the released TENORM, excluding inhalation of radon and its short half-life (less than 1 hour) radon progeny, in excess of 10 mrem (0.1 millisievert) per year, excluding natural background.

E. Actions taken to confine TENORM on site or to remediate sites shall be based on expected longevity related controls for 1000 years.
