ResMon1 U.S. NUCLEAR REGULATORY COMMISSION May 1975 9 REGU WOPJ GU DE OFFICE OF STANDARDS DEVELOPMENT REGULATORY GUIDE 6.4 CLASSIFICATION OF CONTAINMENT PROPERTIES OF RADIOACTIVE SOURCES CONTAINED IN CERTAIN DEVICES TO BE DISTRIBUTED FOR USE UNDER GENERAL LICENSE A. INTRODUCTION To classify a source under either system, a determina-tion is made of its abdity to withstand the conditions of Section 32.51, " Byproduct MaterN Contained in each environmental test prescribed in the respective DeGes for Use under s 31.5; Requirements for License standard. Classification is determined by physically to Manufature Import or Distribute " of 10 CFR Part testmg two prototy pe sources for each test or by 32, " Specific Licenses te Manufacture. Distribute, or calculations based on previous tests which demonstrate Import Certain Items Containmg Byproduct Materiali that, if the source were tested, it would pass. With one requires, in part, that each application for a specific exception, maintenance of containmen* integrity after license to distnbute devices containing byproduct each test constitutes satisfactory performance of a material to persons generally licensed under @ 31.5 of source. The exception is the ANSI N540 discoloration It' CFR Part 31 include sufficient mformation relating test, for which satisfactor; perirmance is determined
, to qualification testing of a prototype unit to provide by appropnate retention of futmosity during the test.
reasonable assurance that the byproduct material in the device will be adeo.sately contained. Frequently, reten-non of the byn.oduct material within the device is C. REGULATORY POSITION dependent on the containment properties of the source.
This regulatory guide identifies terminology acceptable The sealed source classification systems contained in to the NRC staff for describing the contamment USASI N5.10-1968' and ANSI N540-1975' provide properties of a source on a prototype testing basu.

When either classification system is so used, the the American National Standards Insutute Committee applicant should state whether calculational techniques N43-3.3, developed a classification system for scaled or physical testing techniques were applied. If the latter sources (USASI N5.10-1968).'
