REGISTRY OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF SEALED SOURCE OCT 21 1998 NO.: NR-300-S-874-S DATE:
PAGE 2 OF 5 SEALED SOURCE TYPE: Radiography Source DESCRIPTION:
The Gamma Industries Model PL-3 source assembly is designed for use in the Gulf Nuclear Model 10X exposure device.
The Gamma
. Industries Model PL-4 source assembly is designed for use in the l
Source Production and Equipment Company,. SPEC CHECK Model II exposure device and the Pittsburgh Testing Laboratory Model PTL j
125U and 230U.
Both sources are doubly encapsulated and constructed of Type 304 or Type 316 stainless steel using heliarc (TIG) welding.
The wall thickness is maintained at a-minimum of 0.30" (7.62 mm) and is provided with a threaded body for securing in the exposure device.
LABELING:
The source capsules are not large enough to allow direct labeling; however, the exposure device which contains the source capsule is labeled.
For additionalzlabeling information, precise
-refer to the particular exposure device in which the source is to be_used.
DIAGRAM:
See Attachment 1.
CONDITIONS OF NORMAL USE:
The PL-3 AND PL-4 series source assemblies are designed for use in the Gulf Nuclear Model 10X, SPEC CHECK II, and PTL Model 125U and 230U industrial radiography exposure devices.
PROTOTYPE TESTING:
The source has a classification of ANSI 77E43515 as described in 7WSI publication N542-1977.
The manufacturer states that prototype sources have met the test criteria specified in the

' EXTERNAL RADIATION LEVELS:
Theidose rate for Ir-192 is 5.9 R/hr per curie at l' (30.38 cm).
QUALITY-ASSURANCE AND CONTROL:
)
Each source;is wipe 1 tested after-the capsule is welded.
If the results.of~the leak' test ore doubtful, then a hot. water bubble test is conducted.- No source will be shipped.if removable contamination' exceeds 0.005 microcurie (185 Bq)..
Sourc'e activities'are checked against'a standard by using an ion-
' chamber.
A' decay chart.and source tag are supplied with each source, providing information concerning the activity and leak test results.

-SAFETY ANALYSIS ~
SUMMARY
The Models PL-3 and PL-4:s'ources are 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' sources were originally approved for licensing purposes by the' Louisiana Division of Radiation Control.
NRC attempted to s
obtain copies of all.information submitted by the registrant in
, support of the' evaluation.
However,.NRC could not locate all the linformation.
Therefore, no safety evaluation of the sources was iperformed as part of the conversion of the certificate to
' inactive status.
