RE: [cdn-nucl-l] Explaining Food Irradiation
point bothered me. But later on in the article, they say that the
x-ray energy is 5 Mev or so, which is in fact considerably higher than
Cs-137 (670 kev) and Co-60 (<1.4 Mev). I guess what they are

Gammas are definitely
more penetrating than X-rays.
This sounds like
