You can also help a teamate extinguish them with a Carbonizer.
Uh? You sure? I thought the carby just made rads invisible o.o So... They stop the damage too? o.o
they stop the damage as long as somebody else is using the carb to extinguish a rad that is on you. you can't use a carb on yourself or else it will only get rid of the visual rad and let the damage continue. you can extinguish the rads but the damage effects linger wherever it was thrown for a second or two.
