Safety Precautions
The radioactive material used in the M1A1 collimator and the M140 alinement device is tritium gas
(H3)
sealed in Pyrex tubes. These sources illuminate the instrumentation for night operations. Tam-
pering 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 Safe-
ty 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 con-
tamination.
5.
Personnel exposed to tritium will notify medical personnel.
