7 Alaska Admin. Code § 18.590
Field radiography is exempt from the requirements of 7 AAC 18.500 - 7 AAC 18.570, except that a registrant may not permit entry into the radiographic exposure area until a survey is conducted to determine that the x-ray machine is off before each entry into the radiographic exposure area. The survey must be conducted with an instrument that is in good working order and is capable of measuring ionizing radiation of the energies and at the dose rates to be encountered, and that has been properly calibrated within the preceding three months or following the last instrument servicing, whichever is later. Survey results and records of boundary locations must be retained for at least five years, or since the most recent inspection by the department, whichever is less.
