Comment on FR Doc # 2026-09877, NRC-2025-1205-0001, from American Society for Radiation Oncology (ASTRO)

Summary: The American Society for Radiation Oncology (ASTRO) supports the proposed updates to modernize NRC regulations for byproduct material use. They specifically advocate for the exemption of certain radionuclides from decommissioning cost estimates, the creation of Standard General Licenses for specific medical uses, the removal of the redundant "physician" definition, and expanded distribution pathways for microspheres to reduce regulatory burdens and improve patient access.
