June 18, 2015 MEMORANDUM TO:
Brian E. Thomas, Director Division of Engineering Office of Nuclear Regulatory Research FROM:
Joseph G. Giitter, Director /RA/
Division of Risk Assessment Office of Nuclear Reactor Regulation
SUBJECT:
RESULTS OF PERIODIC REVIEW OF REGULATORY GUIDE 8.40 This memorandum documents the US Nuclear Regulatory Commission (NRC) periodic review of Regulatory Guide (RG) 8.40, Revision 0, Methods for Measuring Effective Dose Equivalent from External Exposure, published in July 2010. The RG describes dosimetry methods that the NRC considers acceptable for determining effective dose equivalent (EDE) for external (EDEX) radiation exposures. As discussed in Management Directive 6.6, Regulatory Guides, the NRC staff reviews RGs approximately every 5 years to ensure that the RGs continue to provide useful guidance. Documentation of the NRC staff review is enclosed.
Based on the results of the periodic review, the staff concludes that no changes to RG 8.40 are warranted. The staff did not identify any technical or regulatory issues in the review.

NRR/DRA/ARCB Technical Lead:
Manuel A. Jimenez Recommended Staff Action:
Reviewed with Issues Identified for Future Consideration
- 1.
What are the known technical or regulatory issues with the current version of the Regulatory Guide (RG)?
RG 8.40, Methods for Measuring Effective Dose Equivalent from External Exposure, published in July 2010, describes dosimetry methods that the NRC considers acceptable for determining effective dose equivalent (EDE) for external (EDEX) radiation exposures.
The staff did not identify any technical or regulatory issues in the review. Therefore, no changes to RG 8.40 are warranted.
- 2.
What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years?
