REGISTRY.OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF SEALED SOURCE NO.: NR-300-S-869-S DATE: OCT 21 1999 PAGE 2 OF 3 SEALED SOURCE TYPE: Radiography Source Assembly DESCRIPTION:
The Gamma Industries Model A-11-T source assembly is an exception to the nomenclature, concerning the "A" series source assemblies, and therefore, a separate sheet has been issued.
The Model A-11-T source assembly is designed for use in the Gamma Industries Model 180 exposure device. The source is doubly encapsulated using heliarc (TIG) welding. Capsules are fabricated from type 304 or 316 stainless steel. The capsule wall thickness is maintained at a minimum of 0.030" (0.76 mm).
Teleflex cable is inserted into the capsule and connector at least 5/16" (7.94 mm).
A 1/4-28 threaded connector is used which, after attaching to the drive mechanism, is drilled and pinned in place. l l

PROTOTYPE TESTING:
The manufacturer states that prototype sources have met the j criteria specified in ANSI publication N5.10-1968 and are !
classified as E32515.
l QUALITY ASSURANCE AND CONTROL: l Each pigtail assembly is subjected to a 150 lb. (68.04 kg) pull i test prior to radioactive material insertion, and is subjected to a wipe test after the material is sealed in the capsule. If the results of the wipe test are doubtful, then a hot water bubble test is performed. No source shall be shipped if removable contamination exceeds 0.005 microcurie (185 Bq).

LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
l
. The device shall be possessed and used by persons i specifically licensed by the NRC or an Agreement State.

'* This registration sheet and the information contained within
-l the referencea shall not be changed without the written ,
consent of the NRC. I SAFETY ANALYSIS
SUMMARY
The-'Model-A-11-T source is no longer manufactured or distributed by Gamma Industries, Inc. and Gamma Industries, Inc. is no longer in business. Therefore, the registration certificate is being-converted to an inactive registration certificate.
, The. source was~ originally approved for licensing purposes ~by the !
Louisiana ~ Division of Radiation Control. NRC attempted to obtain ,
copies of all information submitted by the registrant in support of the evaluation. However, NRC could not locate all the j information. .Therefore, no safety evaluation of the source was performed as part of the conversion of the certificate to
-inactive status. i l
