surely you’re not suggesting that x-rays/gamma rays aren’t electromagnetic radiation as much as microwaves? [wink]
the notion: microwaves cause waters to flip back and forth and create enough kinetic energy to kill (eventually) any living thing with water in it. so a microwave is likely a sterile environment for the most part…? “no!” say these researchers, as they can culture bacteria from swabs from inside some test microwaves. and what this old biochemist is fecklessly suggesting is that there are likely regions inside a standard microwave oven which don’t actually receive ‘much’ microwave radiation and it’s there the bugs may persist. kinda tedious i know.
