The
Alabama Air National Guard (Montgomery,
AL) had a thermal night time analyzer with a 40 mCi,
Cd-109 source. The source was last inventoried on 1/30/2015. On 4/28/2015, the analyzer was transferred to the disposal facility at the Defense Logistics Agency (
DLA) at Robins Air Force Base in
Georgia. The Army does not send radioactive sources to this
DLA for disposal. The Army has verified receipt of the source at the
DLA and is currently trying to determine if the source is still there or has been destroyed.

The following report was received from the licensee via e-mail:
[The following is] updated information concerning the improper transfer of the Thermo Niton Analyzer by the Alabama Army National Guard to Defense Logistics Agency (DLA) Disposition Services. We were successful in contacting the manufacturer and got information concerning the assay date of the Cd-109 source. Their records indicate an assay date of 15 April 2008. The analyzer was sent to DLA on 28 April 2015. According to our calculations, this drops the activity from 40 mCi to approximately 0.86 mCi from when it was shipped out to DLA. We are still working with DLA Disposition Services to track the location of the analyzer.
Notified the R1DO (Dwyer) and NMSS Events Notification (via e-mail).
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than
IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as
moisture density gauges or thickness
gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
