| Title | Unplanned Tritium Contamination During Maintenance |
| Event Description | On July 6, 2006 a range indicator SSDR no. NR-155-S-116-S containing [four] 0.8 Ci [curies] tritium lamps [3.2 curies total] was broken during a maintenance procedure at Ft. Bragg, NC Special OPS, 3rd Group Direct Support weapons room, Bldg E-1978. The Ft. Bragg RSO was notified on 7 July 2006 of the incident. Improper maintenance procedure was the reason for the breakage of the tritium sealed source. Two persons were involved in the incident. One tritium bioassay was taken of one individual. The second individual did not have a bioassay taken due to the fact he went on TDY [Temporary Duty] before the discovery of the accident. Leak test of the broken range indicator showed removable contamination of 0.95 microcuries. An area survey of the weapons room by the Ft. Bragg RSO showed a maximum contamination of 0.3 micro curies (64,944 dpm). The Ft. Bragg RSO closed and secured the arms room from re-entry of personnel. The Ft Bragg RSO performed decontamination of the weapons room and brought the tritium removable contamination below regulatory concerns (<10,000 dpm). The licensee was notified of the incident on July 12, 2006. |
