SUMMARY: Issuance and Availability of Regulatory Guide 6.1, Revision 2,

SUPPLEMENTAL INFORMATION

The U.S. Nuclear Regulatory Commission (NRC) has issued revisions to existing guides in the agency's ``Regulatory Guide'' series. This series was developed to describe and make available to the public information such as methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

Revision 2 of Regulatory Guide 6.1, ``Leak Testing Radioactive Brachytherapy Sources,'' was issued with a temporary identification as Draft Regulatory Guide DG6003. This guide directs the reader to methods and procedures acceptable to the staff of the NRC for leak testing radioactive brachytherapy sources. Possession and use of brachytherapy sources is an activity requiring a license pursuant to Title 10, section 30.3, ``Activities Requiring License,'' of the Code of Federal Regulations (10 CFR 30.3). The requirements in 10 CFR 35.67, ``Requirements for Possession of Sealed Sources and Brachytherapy Sources,'' state in part, that the sources are to be periodically leak tested and that the test be capable of detecting the presence of 185 becquerel (Bq) (0.005 microcurie ([mu]Ci)) of radioactive material in the sample. The regulations also require that the source be immediately withdrawn from use if the test reveals the presence of 185 Bq (0.005 [mu]Ci) or more of removable contamination.

This regulatory guide endorses the methods and procedures for leak testing radioactive brachytherapy sources contained in the current revisions of NUREG1556, Volume 3, ``Consolidated Guidance about Materials Licenses: Applications for Sealed Source and Device Evaluation and Registration'' and NUREG1556, Volume 9, ``Consolidated Guidance about Materials Licenses: ProgramSpecific Guidance about Medical Use Licenses'' as a process that the NRC staff has found to be acceptable for meeting the regulatory requirements.

II. Further Information

In January 2008, DG6003 was published with a public comment period of 60 days from the issuance of the guide. No comments were received and the public comment period closed April 18, 2008.
