| Title | Lost Am-241 Check Source |
| Event Description | Organization Possessing Source(s): 711HPW, USAFSAM/OE.
Specific Location(s): Wright-Patterson AFB, OH Bldg. 20840, Room W329D, OEA Radioactive Material Storage. What Happened: One (1) each Isotope Product Laboratory, 12.8 nCi Am-241 check source, RP# 0895 was to be shipped, along with three other sources, to Nellis AFB in support of USAFSAM/OEC personnel. The PRSO [Permit Radiation Safety Officer] could not immediately locate RP# 0895. The PRSO checked the RAM [Radioactive Material] sign-out log to determine if the source had been signed out to other OE personnel. The log did not show evidence of the source having been signed out. The PRSO questioned Radioanalytical Lab, Dosimetry Lab, Calibration Lab, AFRAT, Consulting and Education personnel to determine if anyone was using the source. All of them had a negative reply. All laboratories were thoroughly searched as were the OEC equipment cases used in the Nellis operations. AFRAT equipment cases in WRM were also searched. The source was not located. The PRSO determined the source had last been accounted for during the RAM inventory dated 17 August 2015. Additional investigation revealed that the prior PRSO had been requested to send the source, along with two other sources, to Nellis AFB in support of OEC personnel in September 2015. These sources were never signed out of the inventory when sent to Nellis AFB. Additionally, no OEC personnel recall using the source during that period. The other two sources requested were received back at USAFSAM on 5 October 2015. DOE personnel working with OEC personnel at Nellis AFB, as well as the Nellis IRSO [Installation Radiation Safety Officer], were contacted to see if they had the source in their possession. All had a negative reply. It cannot be determined if the source was lost at USAFSAM or Nellis AFB. The PRSO contacted the IRSO, at 1531, 17 February 2016 to inform him of the potential lost source. USAF Master Materials License: 42-23539-01AF Docket: 030-28641. Applicable USAF RAM Permit: OH-00563-00/14AFP Docket: 030-00563. Commodity (i.e., compasses, etc.): Isotope Product Laboratory check source. Radioisotope(s) Involved: Am-241 Activity: 12.8 nCi Sealed Source Model/Serial No: K-845/0895 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.
