NRR/DRA/ARCB Technical Lead:
Timothy Barvitskie Recommended Staff Action:
Reviewed with no issues identified 1.
What are the known technical or regulatory issues with the current version of the Regulatory Guide (RG)?
Regulatory Guide 8.40, Revision 0, issued in July 2010, describes dosimetry methods that the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for determining effective dose equivalent (EDE) for external (EDEX) radiation exposures.
No technical or regulatory issues were identified in the review.
The guidance continues to be acceptable for determining EDE for EDEX radiation exposures. Therefore, no changes to RG 8.40, Revision 0, 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?
As no technical or regulatory issues were identified, there is no impact on internal or external stakeholders resulting from these activities.
3.
What is an estimate of the level of effort needed to address identified issues in terms of full-time equivalent (FTE) and contractor resources?
As no technical or regulatory issues were identified, no resources are required.
4.
Based on the answers to the questions above, what is the staff action for this guide (Reviewed with no issues identified, Reviewed with issues identified for future consideration, Revise, or Withdraw)?
Reviewed with no issues identified.
5.
