Congratulations to the researchers at
Washington University. It sounds like a potential
lifesaver -- although I believe that a credible
"dirty bomb" scenario leading to multi-Gray levels
of exposure has not yet been postulated..
A question comes to mind. Since the
protection works by suppressing apoptosis, and
since apoptosis is one of the mechanisms
postulated for protection against the effects of
low-level radiation, is there perhaps the
potential for over-enthusiastic use of such
pills? Should they be limited to individuals with
life-threatening levels of exposure -- say above
~2.5 Gy? (An acquaintance received almost 2 Gy
[whole body] some 50 years ago, and he is now a
Is there a chance that "protective"
administration to low-dose subjects could be
counterproductive, leading to the survival of
cancer-precursor cells that otherwise would be
