RE: Missing Exit Signs
Carol and other Radsafers
That is the ALI for tritiated water. I don't know what the one for luminous
paint is but it should be higher; i.e. even a smaller dose concern.
My concern with this type of "incident" is not dose or risk , but "poor
practise". Organizations should know better!

Dear Radsafers:
Given the fact that the ALI for ingestion or inhalation of tritium is 80
mCi, there probably isn't much to worry about. If you tell the public that
a good treatment for tritium internalization is beer, and that anyone
contaminated should go home and tank up, maybe a lot of folks would calm
down. Especially if they get a little drunk.............!
