Final Regulatory Guide: Issuance, Availability

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Issuance and Availability of Regulatory Guide, RG 
8.40, ``Methods for Measuring Effective Dose Equivalent From External 


Regulatory Commission, Washington, DC 20555-0001, telephone: (301) 415-
3162 or e-mail [email protected].


I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing a new guide 
in the agency's ``Regulatory Guide'' series. This series was developed 
to describe and make available to the public information such as 
methods that are acceptable to the NRC staff for implementing specific 
parts of the agency's regulations, techniques that the staff uses in 
evaluating specific problems or postulated accidents, and data that the 
staff needs in its review of applications for permits and licenses.
    Regulatory Guide 8.40 was issued with a temporary identification as 
Draft Regulatory Guide, DG-8039. This guide describes dosimetry methods 
that the NRC considers acceptable for determining the effective dose 
equivalent (EDE) for external (EDEX) radiation exposures. These methods 
provide a conservative estimate of the EDEX and may be used to 
calculate the total effective dose equivalent (TEDE) in demonstrating 
compliance with TEDE-based NRC regulatory requirements.

II. Further Information

    In September 2009, DG-8039 was published with a public comment 
period of 60 days from the issuance of the guide. The public comment 
period closed on November 26, 2009. The staff's responses to the public 
comments received are located in the NRC's Agencywide Documents Access 
and Management System under Accession Number ML100620118. The 
regulatory analysis may be found in ADAMS under Accession No. 
ML101940038. Electronic copies of RG 8.40 are available through the 
NRC's public Web site under ``Regulatory Guides'' at http://www.nrc.gov/reading-rm/doc-collections/.
    In addition, regulatory guides are available for inspection at the 
NRC's Public Document Room (PDR) located at 11555 Rockville Pike, 
Rockville, Maryland. The PDR's mailing address is USNRC PDR, 
Washington, DC 20555-0001. The PDR can also be reached by telephone at 
(301) 415-4737 or (800) 397-4205, by fax at (301) 415-3548, and by e-
mail to [email protected].
    Regulatory guides are not copyrighted, and Commission approval is 
not required to reproduce them.

    Dated at Rockville, Maryland, this 13th day of July 2010.

    For the Nuclear Regulatory Commission.
