| Title | Agreement State Lost Radioactive Source |
| Event Description | University of Mass - Amherst called [Massachusetts Radiation Control Program] to report a missing Ni-63 source in an ECD detector. A Varian Model 3700 gas chromatograph [GC] machine was due for leak testing on 11/15/04. The unit could not be found and was presumed missing. The unit's ECD contained a Ni-63 source (8 milliCurie) and had serial number A3240. In Sept / Oct of 2004, laboratory equipment was moved and / or sent to the trash. It is suspected that the missing GC was mistakenly sent out for disposal at that time, and in Nov. 2004, the licensee determined the unit was missing.
The calibration date of the source activity was not known at the time of the report. The last known confirmed inventory of the device was when the last leak test was performed in May 2004 |
