NUCLEAR REGULATORY COMMISSION

[NRC-2026-3730]


Draft Regulatory Guide: Release of Patients Administered 
Radioactive Material

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft guide; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment a draft Regulatory Guide (DG), DG-8070, ``Release of 
Patients Administered Radioactive Material.'' This DG is proposed 
Revision 2 of Regulatory Guide (RG) 8.39 of the same name. The proposed 
revision provides methods that are acceptable to the NRC staff for the 
release of individuals, referred to as patients in this revision, after 
a medical procedure involving the administration of unsealed byproduct 
material, such as radiopharmaceuticals, or implants that contain 
radioactive material.

DATES: Comments must be submitted electronically using https://www.regulations.gov by 11:59 p.m. Eastern Time on September 10, 2026.

ADDRESSES: Submit your comments, identified by Docket ID NRC-2026-3730, 
at https://www.regulations.gov. If your material cannot be submitted 
using https://www.regulations.gov, call or

II. Additional Information

    The NRC is issuing for public comment a DG in the NRC's 
``Regulatory Guide'' series. This series was developed to describe 
methods that are acceptable to the NRC staff for implementing specific 
parts of the agency's regulations, to explain techniques that the staff 
uses in evaluating specific issues or postulated events, and to 
describe information that the staff needs in its review of applications 
for permits and licenses.
    Proposed RG 8.39 Revision 2, entitled ``Release of Patients 
Administered Radioactive Material,'' is temporarily identified by its 
task number, DG-8070.
    The existing version of RG 8.39 (Revision 1) was published in April 
2020. The NRC previously published for comment a draft update of RG 
8.39 (DG-8061), in April 2024, received comments relating to the 
technical complexity and requests for more examples to be included, and 
did not thereafter finalize that update. The NRC has now refined a 
draft revision to RG 8.39 and has included draft revisions in DG-8070 
to align with proposed revisions to section 35.75 of title 10 of the 
Code of Federal Regulations (10 CFR) as part of a proposed rule, 
``Reforming and Modernizing the NRC's Radiation Protection Framework'' 
(91 FR 43456; July 15, 2026), that addresses section 5(b) of Executive 
Order 14300.
    The proposed revision provides methods that are acceptable to the 
NRC staff for the release of individuals, referred to as patients in 
this revision, after a medical procedure involving the administration 
of unsealed byproduct material, such as radiopharmaceuticals, or 
implants that contain radioactive material. More specifically, DG-8070 
provides guidance and examples for application of new definitions and 
dose limits related to medical uses of byproduct material that would be 
introduced by the referenced proposed rule, including guidance related 
to doses to caregivers.
    Additionally, DG-8070 incorporates up-to-date methodologies based 
on National Council on Radiation Protection and Measurements (NCRP) 
Report No. 155, ``Management of Radionuclide Therapy Patients,'' 
fundamentals for calculating the radiation dose received by members of 
the public from a patient containing byproduct material. DG-8070 also 
includes updates to reflect the evolution of the medical use of 
byproduct material since the last revision of RG 8.39 (Revision 1) was 
issued. This DG is intended to enable licensees to make more accurate 
estimates of the timing, circumstances, and risks associated with 
patient release; public doses from the released patients; and when 
instructions or records are required.
    The staff is not issuing for public comment a separate draft 
regulatory analysis for this draft regulatory guide. The draft 
regulatory analysis associated with this draft regulatory guide was 
issued for public comment with the proposed rule, ``Reforming and 
Modernizing the NRC's Radiation Protection Framework'' (91 FR 43456). 
That draft regulatory analysis assesses the value associated with 
issuing or revising regulatory guides as well as alternative courses of 
action (ADAMS Accession No. ML26180A025).

III. Backfitting, Forward Fitting, and Issue Finality

    The NRC staff may use this RG as a reference in its regulatory 
processes, such as licensing, inspection, or enforcement. Backfitting, 
forward fitting, and issue finality considerations do not apply to 10 
CFR part 35 licensees and applicants because 10 CFR part 35 does not 
include backfitting or issue finality provisions, and the forward 
fitting policy in Management Directive 8.4, ``Management of 
Backfitting, Forward Fitting, Issue Finality, and

[[Page 51751]]

Information Requests,'' does not apply to these licensees.

IV. 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.

V. Executive Order (E.O.) 12866

    The Office of Information and Regulatory Affairs determined that 
this DG is not a significant regulatory action under E.O. 12866.
    Authority: 42 U.S.C. 2011 et seq.
