March 1974U.S. ATOMIC ENERGY COMMISSIONSREGULATORY GUlCI01 DIRECTORATE OF REGULATORY STANDARDSREGULATORY GUIDE 6.4CLASSIFICATION OF CONTAINMENT PROPERTIESOF SEALED RADIOACTIVE SOURCES CONTAINED INCERTAIN DEVICES TO BE DISTRIBUTED FOR USE UNDER GENERAL LICENSEE
A. INTRODUCTION
Section 32.51, "Certain Measuring, Gauging orControlling Devices Gencrally Licensed Under §31.5 ofthis Chapter: Requirements for License to Distribute,"of 10 CFR Part 32, "Specific Licenses to Manufacture,Distribute, or Import Exempted and Generally LicensedItems Containing Byproduct Material," requires, in part,that each application for a specific license to distributedevices containing byproduct material to personsgenerally licensed under §31.5 of IOCFR Part 31include sufficient information relating to qualificationtesting of a prototype unit to provide reasonableassurance that the byproduct material contained in thedevice will not be lost. Frequently, retention of thebyproduct material within the device is dependent uponthe containment properties of a. sealed source. Thisregulatory guide identifies terminology acceptable to theRegulatory staff for describing the containmentproperties of a sealed source based on prototype testing.
B. DISCUSSION
The USA Standards Institute Committee N5.4, nowthe American National Standards Institute CommitteeN43-3.3, developed a classification system for sealedsources (USASI N5.10. 1968).' To classify a sealedsource under the system, a determination is made of itsability to withstand the conditions of eachenvironmental test prescribed in the standard.Classification is determined by physically testing twoprototype sources for each test or by calculations basedon previous tests which demonstrate that, if the sourcewere tested, it would pass. Maintenance of containmentintegrity after each test constitutes satisfactoryperformance of a source.
C. REGULATORY POSITION
The sealed source classification system contained inUSASI N5.10.1968' provides acceptable terminologyfor use in describing the containment properties of asealed source used in a device intended for distributionfor use under the general license in §31.5 of I0 CFRPart 31. When the classification system is so used, theapplicant should state whether calculational techniquesor physical testing techniques were applied. If the latterwere applied, the integrity (leak) test(s) used todetermine conformity with the assigned classificationshould be identified and described.Copies may be obtained from the American NationalSi-ndards Institute, Inc., 1430 Broadway.
