LOST/MISSING DETECTION SOURCE

The following was received by email:

"Per your request, I'm sending this email as a follow-up to my telephonic notification to your office that occurred earlier today (re: 10 CFR 20.2201).

"We're reporting the apparent loss (presently unknown whereabouts) of an aggregate quantity of approximately 95 mCi of Ni-63 housed in the following seven generally licensed devices (GLDs):

- 3 ea. x Smiths Detection SABRE 2000s (up to 15 mCi Ni-63 ea.)
- 2 ea. x Smiths Detection SABRE 4000s (up to 15 mCi Ni-63 ea.)
- 2 ea. x GE VaporTracers (up to 10 mCi Ni-63 ea.)

- 19 May 2016: Tinker AFB installation RSO attempted to schedule semiannual swipe sample collection for May 2016. The unit possessing/using GLDs indicated that the GLDs had been transferred. Installation RSO advised unit to present documentation.

- 23 May 2016: Unit reported to installation RSO that they were still looking for paperwork.

- 13 Jun 2016: After an exhaustive search of records and information management systems, neither the installation RSO or the unit found any documentation for GLD transfer.

- 16 Jun 2016: Installation RSO notified the unit commander; continues to investigate.

- 20 Jun 2016: Installation RSO notified the USAF Radioisotope Committee Secretariat by telephone and then by email to report situation."

The above report of a possible lost or missing source involves sources not specifically licensed under the MML (Master Material License).

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.
