Title	Unplanned Contamination Due to a Broken M1A1 Collimator
Event Description	During an exercise conducted in May 2004 at Camp Shelby, MS an M1A1 Collimator, NSN 1240-00-332-1780, containing 10 Curies Tritium was removed from service, i.e., possibly broken, and double-bagged for storage. The device was subsequently transported from Camp Shelby to Shelbyville, TN and ultimately forwarded to the Combined Support Maintenance Shop of the TN National Guard located in Smyrna, TN for repair. A routine pre-maintenance wet swipe test indicated contamination levels as high as 619,094 disintegrations/min using a liquid scintillation meter. This corresponds to an activity of 0.27 microcuries. Two TN National Guard staff have submitted samples for bioassay. The results will be available on Monday, 11/22. Radiation surveys conducted at the Shelbyville and Smyrna, TN storage locations were negative. The device is currently double-bagged in the low level rad waste storage area of the Combined Support Maintenance Shop awaiting disposal.
