The Nuclear Regulatory Commission (NRC) is amending its regulations to revise the radiation protection training requirement so that it applies to workers who are likely to receive, in a year, occupational dose in excess of 100 mrem (1 mSv); revise the definition of ``Member of the public'' to include anyone who is not a worker receiving an occupational dose; revise the definition of ``Occupational Dose'' to delete reference to location so that the occupational dose limit applies only to workers whose assigned duties involve exposure to radiation and not to members of the public; revise the definition of ``Public Dose'' to apply to dose received by members of the public from material released by a licensee or from any other source of radiation under the control of the licensee; assure that prior dose is determined for anyone subject to the monitoring requirements in 10 CFR part 20, or in other words, anyone likely to receive, in a year, 10 percent of the annual occupational dose limit; and retain a requirement that known overexposed individuals receive copies of any reports of the overexposure that are required to be submitted to the NRC. This change highlights a requirement which requires licensees to inform members of the public that they have been overexposed. These amendments are necessary to clarify criteria that determine when radiation protection training is required and to restore a notification requirement.
