In foods, several reactions commonly give rise to free radicals:
1) Abstraction of electrons from polyunsaturated fats by molecular
2) Photolysis, either mediated by pigments, or via UV light (UV is
3) Production of OH radicals by iron, especially heme
4) Attack on polyunsaturated fatty acids by lipoxygenase
In vivo, several reactions in addition to the above are common:
1) Electron leakage from respiration
2) Arachidonate oxidation in cell signaling (inflammation,
3) Oxidation of certain naturally occuring and xenobiotic toxins.

The issue is practical importance. You probably get more "radiolytic
products" into your body by stubbing your toe than by eating irradiated
meat. Getting a suntan is orders of magnitude more dangerous. Losing
sleep worrying about being hit by an asteroid would be time better

This subject has been studied for many years. I offered to send you
hundreds of literature citations that I found doing a few minutes of
searching. You apparently don't want to see these.
Probably no amount of evidence would convince you that irradiation is
okay, because there are issues here that go beyond safety. Let's talk
about those political issues. They are more relevant and interesting
