(A) The licensee or registrant authorizes a planned special exposure only in an exceptional situation when alternatives that might avoid the dose estimated to result from the planned special exposure are unavailable or impractical;
(B) The licensee or registrant, and employer if the employer is not the licensee or registrant, specifically authorizes the planned special exposure, in writing, before the exposure occurs.
(C) Before a planned special exposure, the licensee or registrant ensures that each individual involved is:
(i) Informed of the purpose of the planned operation; and
(ii) Informed of the estimated doses and associated potential risks and specific radiation levels or other conditions that might be involved in performing the task; and
(iii) Instructed in the measures to be taken to keep the dose as low as reasonably achievable (ALARA) considering other risks that may be present;
(D) Prior to permitting an individual to participate in a planned special exposure, the licensee or registrant ascertains prior doses as required by 180 NAC 4-009.02 during the lifetime of the individual for each individual involved;
(E) Subject to 180 NAC 4-005.02, the licensee or registrant must not authorize a planned special exposure that would cause an individual to receive a dose from all planned special exposures and all doses in excess of the limits to exceed:
(i) The numerical values of any of the dose limits in 180 NAC 4-005.01 in any year; and
(ii) Five times the annual dose limits in 180 NAC 4-005.01 during the individual's lifetime;
