| Title | Lost/Missing Calibration Source |
| Event Description | The following was received by email:
Notification from Master Material License [MML] No. 42-23539-XXAF, issued to the Department of the Air Force. The following report of a possible lost or missing source likely involves a source not specifically licensed under the MML: On 13 April 2015 at 1030 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.91915e-4 months <br />, an officer newly assigned to Cannon AFB [Air Force Base] discovered a source on the radioactive material inventory he could not physically locate. The source was listed as an Am-241 check source for a Smiths model 1500 instrument, with no information provided except for a previous storage location. The officer could not locate any records of disposition for this source, but continues to investigate disposition records for the base. The officer interviewed a predecessor who asserted the Am-241 line item on the inventory could be a clerical error. The licensee contacted Smiths Detection which to date could not verify the existence of a Smiths Model 1500 or an Am-241 check source. They are unaware of any exposures at this time. The base will ensure complete/accurate data entry for radioactive material inventories and subsequent verification of inventory through physical 'eyes-on' inventories. 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.
