You never know when that one particular Mike, if there is NO SAFE DOSE you better stop living, but quick! Who knows when you might get cancer. This gets back to the "reliability" thread which discussed probability of harm based upon statistics. If you aren't willing to risk a little, you end up at a dead-end. Better stop being capitalistic, too.

You picked the wrong guy to discuss Nuclear Physics with - you'll lose! He's even more of a geek than me!
