SAFETY ANALYSIS
SUMMARY
The Model GP 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
~
l 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 suppart
'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.
