Title	Agreement State Report - Licensed Material Recovered at a Landfill
Event Description	NOTIFICATIONS: On December 6, 2013 the PA Department of Environmental Protection (PA DEP) was notified of a radiation alarm at Modern Landfill in York, PA. A health physics consultant for the landfill had responded and determined that two bare molybdenum-99 (Mo-99) generator cores were the cause of the alarm. The Mo-99 generators had their labels intact and noted an activity of 18 curies (Ci) on 10/29/2013 and 11/06/2013. Expiration dates were 11/12/2013 and 11/19/2013 respectively. Per 10 CFR 20.2201, decay correcting the activity would prompt a 30-day report per 10 CFR 22.2201(a)(ii); however, after further investigation and discussion with the licensee, a conservative (immediate) report per 10CFR 20.2201(a)(i) may be required. EVENT DESCRIPTION: The December 6th initial notification to the PA DEP/BRP was due to a load of solid waste possibly containing Mo-99, versus Tc-99m which is often found to set off landfill radiation alarms. Upon off-loading the waste and discovery of two bare Mo-99 generator cores and investigation the following week, the serial number on each of the Mo-99 generator labels revealed they were from a Pennsylvania nuclear pharmacy licensee, Cardinal Health (C. H.), PA-0385. A reactive inspection was initiated. The RSO for C.H. concluded that the generators may have been stolen after their expiration date, and thus would involve a decayed activity of 510 mCi. This is greater than 1,000 times the quantity specified in 10 CFR 20 Appendix C for Mo-99 (that is, greater than 100 mCi). PA DEP/BRP is expecting the licensee to assess the range of whole body and extremity doses to the individual(s) that disassembled these Mo-99 generators using conservative bounding assumptions. No one has admitted to the removal of the Mo-99 from the C.H. facility. CAUSE OF THE EVENT: Possible theft as a crime of opportunity for scrap lead shielding. ACTIONS: A reactive inspection by the PA DEP Regional Office has already occurred and further evaluation of the potential individual radiation exposure and needed corrective actions are ongoing. PA Event Report ID No: PA130029 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.
