We can radiate food to prevent spoilage – so long as the food remains sealed in a package it was irradiated in.
Radiation kills things, like cells and bacteria.
Now, suppose you take a deceased body, within several minutes of death, and place it in a high radiation area, say the containment bath for used fuel rods in a nuclear reactor or within a chamber full of radioactives that are not intense enough to generate heat, but powerful enough to give a lethal dosage to an unprotected person in something like a 30 second exposure. Kind of like what happened to that scientist who got exposed to fission while making the first atomic bomb.
Would the body decay?
Decay is due only to bacterial action. Would the intense radiation kill all bacterial and prevent the inevitable decay? So, would the body stay intact so long as it is being exposed to the radiation?
We also know that intensely radioactives glow. After say, a month, if the body was removed, would it glow and how long might it be before it started to decay?
Intense radiation can change molecular structures. Would the radiation over a prolonged period of time change molecular formations in the body – say like organic lead to metallic? Organic potassium into crystalized?
