Ignorance on display
Years ago I worked with a millwright on a refueling outage at a nearby nuclear plant. During our two week training before beginning work, they warned us that there were about 2400 different things which could trigger an automatic shutdown and the resultant steam dump. Most were very minor.
However, they said that the steam dump would sound like a 747 landing right on top of you.
Tritium is pretty damn safe.
I can’t think of a single way it could kill you, or even make you ill. The beta emitted won’t even penetrate the layer of dead skin on your body. You’d have to deliberately inhale the pure gas, and that could kill you, but only because of oxygen deprivation. Tritonated water won’t kill you either, unless you drown in it.
Aside from that, panic over Tritium, is likely more deadly or worrysome.
