Was doing some digging on DU and ammo boxes etc would be no concern as the penatrator is seal in the projectile and it states "No additional protective measures are required for unfired DU munitions beyond those required for all amunitions "
I like this though
"You are in a situation where DU presents a hazard if you—
Are in, on, or near (within 50 meters) an armored combat vehicle at the time it is struck by DU munitions or an M1A1/A2 Heavy Armor tank when it is struck and breached by any munition (DU or non-DU)."
I think DU during this event would be the least of my concerns
This is also a nice quote "Like lead and other heavy metals, internalizing large amounts of uranium could affect your health"
