NUCLEAR REGULATORY COMMISSION
[NRC-2021-0217]
Monitoring Criteria and Methods To Calculate Occupational
Radiation Doses
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing
Revision 1 to Regulatory Guide (RG) 8.34, ``Monitoring Criteria and
Methods to Calculate Occupational Radiation Doses.'' This revised
guidance is an approach that is acceptable to the staff of the NRC for
monitoring and determining the dose to occupationally exposed
individuals.
It provides updated criteria and methods to calculate occupational
radiation doses to demonstrate compliance with the NRC regulations and
it reflects current generally accepted methods and procedures available
for radiation protection.
DATES: Revision 1 to RG 8.34 is available on August 29, 2022.

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC is issuing a revision to an existing guide in the NRC's
``Regulatory Guide'' series. Regulatory guides were developed to
describe and make available to the public information and 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 issues or postulated events, and data that the staff needs in
its review of applications for permits and licenses.
The NRC is issuing Revision 1 of RG 8.34 to describe an approach
that is acceptable to the staff of the NRC for calculating the total
effective dose equivalent as the sum of the effective dose equivalent
(for external exposures) and the committed dose equivalent for internal
exposures. In addition, it includes the following guidance:
performing prospective dose evaluations to determine the
need for required monitoring to meet the occupational dose monitoring
requirements of section 20.1502 of title 10 of the Code of Federal
Regulations (10 CFR),
monitoring of unplanned, unintended doses,
monitoring dose from hot particles or contamination on or
near the skin,
defining the term ``dosimetry processing'' and explaining
when there are requirements for processing by an accredited National
Voluntary Laboratory Accreditation Program processor,
assessing dose from intakes of radioactive material by
wound injuries, and
calculating soluble uranium intakes
II. Additional Information
The NRC published a notice of the availability of DG-8060 to RG
8.34 (ADAMS Accession No. ML21068A160), in the Federal Register on
December 17, 2021 (86 FR 71676) for a 45-day public comment period. The
public comment period was scheduled to close on January 31, 2022,
however, in response to a public request, the NRC decided to extend the
public comment period until March 2, 2022 (87 FR 4059), to allow more
time for members of the public to
[[Page 52816]]
develop and submit their comments. Public comments on DG-8060 and the
staff responses to the public comments are available in ADAMS under
Accession No. ML22117A049.
III. Congressional Review Act
This RG is a rule as defined in the Congressional Review Act (5
U.S.C. 801-808). However, the Office of Management and Budget has not
found this RG to be a major rule as defined in the Congressional Review
Act.
IV. Backfitting, Forward Fitting, and Issue Finality
RG 8.34, Revision 1, will provide updated guidance for reactor and
non-reactor applicants and licensees regarding acceptable methods for
calculating radiation doses. Issuance of RG 8.34, Revision 1 would not
constitute backfitting, as that term is defined in 10 CFR 50.109,
``Backfitting,'' and as described in NRC Management Directive (MD) 8.4,
``Management of Backfitting, Forward Fitting, Issue Finality, and
Information Requests''; constitute forward fitting, as that term is
defined and described in MD 8.4; or affect the issue finality of any
approval issued under 10 CFR part 52.
V. Submitting Suggestions for Improvement of Regulatory Guides
A member of the public may, at any time, submit suggestions to the
NRC for improvement of existing RGs or for the development of new RGs.
Suggestions can be submitted on the NRC's public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html.
Suggestions will be considered in future updates and enhancements to
the ``Regulatory Guide'' series.
Dated: August 24, 2022.
