Standards for Protection against Radiation, 10 CFR Part 20: A Comparison of theExisting and Revised Rules

摘要

On May 21, 1991, the Nuclear Regulatory Commission (NRC) issued a revision to itsstandards for protection against ionizing radiation, 10 CFR Part 20. Although the revised part (20.1001-20.2401) became effective on June 20, 1991, licensees may defer implementation of the revised rule until January 1, 1993. Licensees continue to be required to comply with the provisions of 20.1-20.601 until the time they adopt the provisions of 20.1001-20.2401. Therefore, between June 20, 1991 and January 1, 1993 both the provisions of 20.1-20.601 and 20.1001-20.2401 are in effect. The NUREG presents a comparative text of the provisions of the revised Part 20 (20.1001-20.2401) to the text of 20.1-20.601 for use by the NRC staff and NRC licensees.
