## Abstract

The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide (RG) 8.21, "Health Physics Surveys for Byproduct Material at NRC-Licensed Processing and Manufacturing Plants." This RG is being withdrawn because there is more up-to-date guidance in NUREG- 1556, "Consolidated Guidance About Materials Licenses," making RG 8.21 obsolete.
