NUCLEAR REGULATORY COMMISSION

Final NUREG: Issuance, Availability

    The Nuclear Regulatory Commission (NRC) has issued NUREG/CR-6112, 
``Impact of Reduced Dose Limits on NRC Licensed Activities--Major 
Issues in the Implementation of ICRP/NCRP Dose Limit Recommendations,'' 
as a final report. On May 21, 1991, the Nuclear Regulatory Commission 
(NRC) published a revision to 10 CFR Part 20, ``Standards for 
Protection Against Radiation.'' The rule became effective in June, 
1991, and licensees were required to implement the regulations on or 
before January 1, 1994.
    The revised 10 CFR Part 20 is based upon the recommendations of the 
International Commission on Radiological Protection (ICRP) in 
Publication 26 (ICRP 1977). In 1991, the ICRP published revised 
recommendations in Publication 60. These recommendations were based 
upon revised dosimetry and epidemiology, including the information 
presented in reports such as the 1988 United Nations Scientific 
Committee on the Effects of Atomic Radiation (UNSCEAR). The new 
recommendations include a revised occupational dose limitation approach 
of 100 mSv (10 rem) in 5 years, with the additional limitation that no 
more than 50 mSv (5 rem) be received in any one year.
    In 1991, the National Council on Radiation Protection and 
Measurements (NCRP) recommended a lifetime limit of 10 mSv (1 rem) 
times age in years (NCRP Report 91). This recommendation was continued 
in recommendations published in 1993 (NCRP Report 116).
    In anticipation of these recommendations, and as a result of the 
epidemiological and dosimetric information available in the last 5 
years, the NRC staff initiated a study by Brookhaven National 
Laboratory (BNL) to analyze the potential impacts of reduced dose 
limits on its licensees. The results of this study are contained in 
this NUREG/CR. During the study period, a relatively small number of 
licensees responded to questionnaires and surveys, thereby limiting the 
extent to which the survey results can be assumed to be an accurate 
representation of the potential impacts of changed dose limits.
    The NRC staff published these results in draft form in January 1994 
to solicit further comments from interested parties regarding the 
impacts of the different possible dose limits discussed in the draft 
NUREG/CR.
    NUREG/CR-6112 is not a substitute for NRC regulations, and 
compliance is not required. The approaches and/or methods described in 
this NUREG/CR are provided for information only. Publication of the 
report does not necessarily constitute NRC approval or agreement with 
the information cited therein.
    Copies of NUREG/CR-6112 may be purchased from the Superintendent of 
Documents, U.S. Government Printing Office, P.O. Box 37082, Washington,
