'DATE:
OCT 21 1993-PAGE 2 OF 5 SEALED SOURCE TYPE:. Radiographic Source Assembly DESCRIPTION:
The Gamma Industries Model A-13-A source assembly is: designed for Luserin the Gamma Industries Model 2-15SA exposure. device.
The active material is metallic-Iridium-192, singly encapsulated in type 304 or-316 stainless steel, using a heliarc_ welding
~
technique.
This source assembly-is a departure from the usual radiography source in that'it contains two (2) sources on a single pigtail, separated by a maximum distance of-four (4) inches (10.16 cm).
The source capsules' closest to the connector in;the assembly _usesla~ side-weld closure, and the source capsule furthest from the connector in the assembly.uses an end-cap closure.
The pigtail connector,. source capsules and locking ball are crimped to 1/8 inch (3.18 mm) stainless steel cable.
-LABELING:
The source capsules ~are_not large.enough to allow' direct labeling.
However, the exposure' device which contains the source capsules-is labeled; and for additional labeling information, please see the certificate of; registration andisafety analysis.
summary for the Gamma' Industries Model-2-15SA exposure device.
DIAGRAM:
See. Attachment 1.
CONDITIONS OF NORMAL USE:
The Gamma Industries Model A-13-A source assembly is intended for
-use only_in the Gamma Industries Model 2-15SA Industrial Radiography exposure devices.
Gamma emission is checked against a standard using an ion chamber.
A decay chart and source tag are supplied with each source, providing information concerning the activity and leak test results.

SEALED SOURCE TYPE:~Radi' graphic Source Assembly _
o Ph0TOTYPEITESTING:
This' source assembly consists of a singly encapsulated universal
-end-weld. capsule and a singly encapsulated side-weld capsule on a l
single pigtail. :Both capsules have.an ANSI classification of 1
77E43515, as described in ANSI' publication N542-1977.
Based on prototype; test data, these, designs are expected to. retain containmentcintegrity under accident conditions likely to occur
'during normal use or transportation.

)
EXTERNAL RADIATION LEVELS:
E The-dose rate from unshielded source of iridium-192 is approximately'5.9 R/hr per curie at 1 ft (30.48 cm).
? QUALITY' ASSURANCE AND' CONTROL:
The manufacturer. maintains pigtail dimensional tolerances at
-11/16 inch (il.59 rmn).
Each source assembly is subjected to, and
.must-successfully pass with no visible distortion, a 200 pound (90.72.kg) pull test prior to insertion of radioactive material.
"After encapsulation,. afwipe test for contamination is made.
If
.the results are doubtful 'then a hot water bubble test is performed.
No source'is shipped,if; removable contamination s
-exceeds 0.005. microcurie ~(185,Bq).
LIMITATIONS AND/OR OTHER'CONSIDERhTIONS OF'USE:
'The.Model-A-13-A=shallsbe possessed and used by specific licensees of U.S$ NRC or AgreementiStates.
O
. These sealed source? designs shall not be subjected to environmental or other conditions'of useJwhich exceed ANSI
-classification 7.7E43515.

-LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE (Cont'd)-
. These sources shall.be leak tested.at intervals not to exceed six (6) months using techniques approved by the licensing authority and capable of detecting 0.005 microcurie (185 Bq) of removable contamination.
. The source assembly.is designed for use in the Gamma Industries Model 2-15SA exposure. device which shall be labeled in accordance with applicable regulations.
. Handling, storage, use, transfer, and. disposal:
To be determined-by the licensing authority.
j This registration' sheet and the information cortained within the references.shall not-be changed withoutithe written consent of the'NRC.
-SAFETY ANALYSIS 1
SUMMARY
The Model'A-13-A source is nollonger 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:theLevaluation.
However, NRC could not 1ocate all the information.
Therefore, no safety evaluation of the source was
. performed'as part of the conversion of the certificate to
' inactive status, l
