Licensees and registrants must demonstrate compliance with dose limits for individual members of the public as follows.

014.01 SURVEYS. The licensee or registrant must make or cause to be made surveys of radiation levels in unrestricted areas and radioactive materials in effluents released to unrestricted areas to demonstrate compliance with the dose limits for individual members of the public in 180 NAC 4-013.

014.02 DEMONSTRATING COMPLIANCE. A licensee or registrant must show compliance with the annual dose limit in 180 NAC 4-013 by:
