These sources illuminate the instrumentation for night opera- tions. Tampering with or removing the source in the field is prohibited by Federal Law. They pose no significant hazard when intact. However, if an M1A1 collimator or an M140 alinement device is discovered to be broken, damaged, or defective, the following procedures will be followed: 1. Evacuate to a safe distance upwind and cordon off immediate area around device. 2. Immediately notify the installation Radiation Protection Officer (RPO) and the Installation Safety Officer (SO). 3. All personnel will stand fast at the safe area until released by the RPO or the SO. 4. Follow the RPO’s instruction for decontamination so as to avoid excess spread of tritium contamination. 5. Personnel exposed to tritium will notify medical personnel. b Change 2
