Tighter Security Considered for Some Category 3 Sources

The U.S. Nuclear Regulatory Commission (NRC) is collecting information from public stakeholders to possibly expand sealed source tracking, license verification, and 10 CFR Part 37 physical security requirements for certain Category 3 quantities of radioactive material.

Targeted materials of interest include Iridium-192. Its inclusion would subject the High Dose Rate (HDR) brachytherapy community to the additional requirements. Molybdenum-99 is not currently under consideration.

To support information gathering, the NRC published a request for comments in the Federal Register and is also convening a series of public hearings, available via webinar. The first public meeting was held Jan. 31, and other sessions are scheduled for Feb. 21 and March 2. See the NRC website for event details and links.

The American College of Radiology is planning to formally respond to the NRC’s request for comments. Interested ACR members can offer input by contacting Michael Peters, director of regulatory and legislative affairs, by phone at 202-223-1670, extension 4546, or by email at mpeters@acr.org.
