A. INTRODUCTION

-Possession and use of brachytherapy sources is an activity iequirirng a license pursuant to section 30.3,"Activities Requiring License," of 10 CFR Part 30.-Rules of General Applicability to 'Licensing of Byproduct Material." Paragraph (e) of section 30.34 in 10 CFR Part 30 provides that the Atomic Energy Commission may incorporate in any license such additional requirements and conditions as it dcems appropriate or necessary in order to protect health or to minimize danger to life or property.A standard condition, included in all AEC licenses for possession and use of' sealed brachytherapy sources requires that these sources be periodically leak tested, that the test be capable of detecting the presence of 0.005 microcurie of radioactivic material on the test sample taken front the source, and that the source be immediately withdrawn from use if the test reveals the presence of 0.005 microcurie or more.This guide describes methods and procedures acceptable tot the Regulatory staff for leak testing radioactive brachytherapy sources.

B. DISCUSSION

Subcommittee N44-2. Therapeutic Radiology, of the American National Standards Institute Committee on Equipment and Materials for Medical Radiation Applications.

N44, has developed a standard presenting uniform criteria and test procedures for the evaluation oI radioactive material leakage from sealed brachytherapy sources. This standard was approved by the American National Standards Institute (ANSI) on July IS, 10373. and dlesignated ANSI N44.2-1973.
