    Hey guys,

    Just thinking on this. When you microwave food, aren't you just heating up the water molecules in the product? Is it bad for you in the sense that it irradiates the food, or? Also, that theory that you shouldn't stand near the microwave when it's on because it kills ... certain ... reproductive ... necessities ... is that true?

    When you heat food up in a conventional oven, you are also irradiating it. In this case with infrared. Microwave are just a different wavelength of the same kind of radiation. Both infrared and microwaves are non-ionizing radiation. Basically this means that they don't directly break up or damage molecules. So unlike X-rays or gamma rays, they are not dangerous in that respect, neither would they alter the food in that sense.

    In terms of of microwave leakage killing certain reproductive necessities: Microwave oven radiation is just not that penetrating. If the microwaves leaking from an oven were strong enough to effect say sperm, they would be strong enough to make your outer skin quite uncomfortably warm. In other words, they would cook your skin before they cook your sperm. Since the levels of leakage needed to do this is many many times that of allowed leakage allowed for microwave ovens, I'm fairly sure that your little soldiers are safe.

    Yeah, the scare comes from overestimating the term "radiation". Like overestimating the term "chemical". People used to feel "electrical" held some malign occult property...

    The only people who are in physical danger from microwaves - and then only if the oven is not functioning correctly - are people who have pacemakers installed.

    Everyone else is only in danger from microwaved foods if they fail to stir them and/or check the temperature of food before putting it into their mouths.

    Why does oven make food more evenly heated than microwave which leaves inside cold?

    It's because microwaves are very efficiently absorbed by water, in dense water rich foods the penetration depth is only about 30mm, if the food is thicker than ~60 mm the centre is not heated directly by the microwaves but by heat transfer from the hot surrounding stuff. If the settings on the oven and cooking times are not adjusted to account for this the outside will be very hot leaving the interior relatively cold.

    What an interesting piece of technology the microwave is turning out to be!

    I still don't put my eyes anywhere near a microwave door. You have no way of knowing if the seal is good.

    I gave myself an RF (radio frequency) burn once, when I touched the centre conductor of an electrical feeder of a 25W radio transmitter - having forgotten to turn it off first. I got a little round lump of cooked flesh just under the skin. It's gone now, but I don't want to risk my eyes by going up close to the microwave oven door.

    How is a man like a microwave oven? Just another thing that heats up instantly and goes off in twenty seconds.
