Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

Health Physics Questions and Answers - Question 2

Question 2: What are the requirements for including dose from non-NRC-licensed sources (x-rays, accelerators, NORM) as part of occupational dose?

Answer: The combined total of the doses from licensed and unlicensed sources (other than background and medical radiation) must be below the Part 20 occupational dose limits. The requirement for inclusion of doses from non-licensed sources is intended to account for occupational doses received while working for activities or with materials that are licensed or controlled by organizations other than the NRC, e.g., states, DOE, etc.. Thus licensees must record and add the doses from non-licensed sources to the doses from licensed sources to obtain the total dose for comparison with the occupational limit.
