# SUPPLEMENTARY INFORMATION:

## I. Introduction 

The U.S. Nuclear Regulatory Commission (NRC) is issuing a revision to an existing guide 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 10.9, “Guide for the Preparation of Applications for the Use of Self-Contained Dry Source-Storage Gamma Irradiators,” was issued with a temporary identification as Draft Regulatory Guide, DG-0019. This regulatory guide directs the reader to the type of information acceptable to the NRC staff for review of an application for the use of a self-contained dry source-storage gamma irradiator. Title 10, Part 36, “Licenses and Radiation Safety Requirements for Irradiators,” of the                     *Code of Federal Regulations*                     (10 CFR Part 36) contains the licensing, design, and radiation safety requirements for irradiators. In addition, licensees and applicants may be subject to portions of the requirements in 10 CFR Part 30, “Rules of General Applicability to Domestic Licensing of Byproduct Material,” and 10 CFR Part 20, “Standards for Protection Against Radiation.”                 

                    This regulatory guide endorses the methods and procedures describing how to apply for a license to use a self-contained dry source-storage gamma irradiator contained in the current revision of NUREG 1556, Volume 5, “Consolidated Guidance about Material Licenses: Program-Specific Guidance                           ( print page 55545)                        about Self-Shielded Irradiator Licenses,” as a process that the NRC staff finds acceptable for meeting the regulatory requirements.                 

## II. Further Information 

                    In April 2008, DG-0019 was published with a public comment period of 60 days from the issuance of the guide.
