Radiation Safe Level is difficult to give a simple answer, but the current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is as low as reasonably achievable; however, not to exceed 5,000 millirems above the 300 plus millirems of natural sources of radiation and any medical radiation. (Refer to the Radiation Area)
Reference Definition by Iitk.ac.in: Radiation Safe Level in the United States the U.S. Nuclear Regulatory Commission (NRC) determines what radiation exposure level is considered safe. Occupational exposure for worker is limited to 5000 mrem per year. For the general population, the exposure is 500 mrem above background radiation in any one year. However for long term, multi-year exposure, 100 mrem above background radiation is the limit set per year.
