I would say, that trying to use tritium exit signs as an RDD, is ridiculous.

If they were of the type I know - filled with gaseous HT - sure no cleanup

would be necessary and would not cost a single cent, because within a few

minutes all of this gas would have been dispersed and diluted to ambient

levels. There would be no mess <SNIP>



I wonder about that -- presumably an RDD involves some sort of explosion.

Wouldn't that cause at least some part of the HT to burn and form HTO ?

While most of that would also disperse as vapour, some might also cause a

mess.... any guesses how much ?

By the way, a colleague pointed out that the 55 Ci in the exit signs would

by now have decayed to 25 Ci, due to 14 years of decay (12.3 yr half-life).
