| Title | Tritium Lamp Broken During Maintenance of a Mortar Sight |
| Event Description | On 4/11/13 at 1300 EDT, a 1 Ci tritium lamp was broken during routine maintenance on a M64 mortar sight unit. The sealed source tritium lamp broke when a wrench hit the tritium module. Surveys were conducted, but the results will not be available until next week. Bioassays are being perform on 4 individuals and based on historic records, the RSO expects minimal intake of less than 5 mrem. The device was bagged, tagged and placed in a secure storage area for future disposal.
The licensee attempted to notify R3 (McCraw).
The US ARMY is retracting this event due to a miniscule bio-assay indicated dose rate to the four workers (maximum dose of 0.9 mRem to an individual) and survey results of the maintenance shop indicating no contamination. The device has been secured and properly stored for future disposal. The licensee notified R3 (McCraw). Notified the R1DO (Joustra), R3DO (Hills) and FSME Events Resource via email. |
