Exit signs need to go to radioactive dumps.

I got a real charge out of this article in BusinessWeek magazine! One of my competitors has based its marketing program on exit signs...Now we find out that exit signs are toxic trash.

Evidently, most of them contain tritium, a radioactive isotope of hydrogen, and the old ones get discarded into landfills where the tritium, a known carcinogen, percolates into the area's drinking water.

It is now required that exit signs must be taken by licensed haulers to special radioactive dumps.
