| Title | Pennsylvania Agreement State Report - Unsecured Radioactive Source |
| Event Description | The following information was obtained from the Commonwealth of Pennsylvania via facsimile:
On April 25, 2011, an Ir-192 source (SN# D36C-5591), 3.36 Ci activity, was removed from a Nucletron microSelectron HDR unit, placed into an approved Type A source storage and transportation container, and moved to a secure designated HDR source storage location, awaiting return to the manufacturer. However, due to miscommunication, the source was never shipped back to the manufacturer and as a result, the source was relocated by contractors approximately a month later to an unoccupied storage room in an uncontrolled area of the building. The source was estimated to have decayed to 2.5 Ci. On October 10, 2011, the unoccupied storage room became the office of a new full-time physicist. The activity was estimated to be 0.69 Ci at this time. On October 27, 2011, the source was discovered during a routine inspection by the Department of Environmental Protection and immediately placed back into the permanent storage area within the HDR storage location. It was determined that the badged physicist who occupied the office received 5.6 mrem, however, his subsequent dosimeter reading indicated no measureable radiation exposure. The unmonitored contractor who moved the source was estimated to have received 0.6 mrem. The source was returned to the manufacturer via [a national shipper] on November 10, 2011. In the future, the new full-time physicist will maintain control of all sources, as well as document when the sources actually leave the facility to be returned to the manufacturers. The licensee has also modified their policies and procedures. The Department [Pennsylvania Department of Environmental Protection] plans another reactive inspection. PA Event Report ID: PA110037 |
