Protect Mortar Components Containing Tritium

Mortars use sighting devices that contain radioactive tritium.  If one of these devices gets banged around and broken, the tritium can leak out.  That poses a health risk if it gets on your skin.  Plus, any radiation leakage must be reported to the local radiation safety officer.

So it’s in your best interest to do everything possible to protect all components containing tritium.  That’s not as much of a problem when it comes to the M64A1/M67 sight units and the M58/M59 aiming post lights.  They have hard cases you can keep them in when they’re not being used.

But things get trickier with the 60mm cannon tube.  Its range indicator contains four separate tritium lamps.  If it’s left unprotected and unsecured in the back of the truck, it can roll around and get banged up by other equipment.  It doesn’t take too big a blow to break one of those lamps.

So before you hit the road, make sure the 60mm cannon tube is secured so it can’t roll every which way.  If possible, give the range indicator extra protection by wrapping it in bubble wrap or a blanket.

If one of the range indicator lamps fails to light up, something is wrong.  You need to report it to your radiation safety officer.
