No, microwave ovens are not a source of low-level muclear radiation.
Microwaves operate by generating microwave electromagnetic radiation. This radiation acts on the contents of the oven and causes what is called dielectric heating. In this process, molecules (primarily water) in the food try to align themselves with the direction of the electromagnetic energy. As the microwave energy is constantly (and very rapidly!) changing is polarization, the molecules will be quickly moved around. This will add energy to the food, and it will appear in the form of thermal energy, or heat. None of this involves nuclear radiation, low-level or otherwise.
Yes they do give off radiation. The way microwaves heat food is by speeding up the
molecular particles within the food thus heating them. The problem is that by making
the particles move so fast it makes it not only unrecognizable by the human body,
meaning of no nutritional value, but also irradiating the food which leads to dead or
mutated cells( like cancer) mostly dead blood cells.
FYI Soviet Russia made mircowaves illegal for sale because of there harmful effects on
food, this ban was revoked in 1976 when Russia changed to a free market after the
cold war.
Microwave ovens use high power electromagnetic radiation (radio) at a frequency
close to 2.5 GHz to do the job of cooking.
Much of the design of the appliance goes into making sure that very little of that
radiation is "given off", and that it stays inside the cooking chamber where it belongs.
The reason for that is not so much any concern that the meatloaf might take longer
to cook if some of the radiation is lost. The concern is that radio RF energy at 2.5 GHz
and at that power level is potentially dangerous.
Here's a little factoid to consider:
Power generated by a microwave radio transmitter
and used to transmit high-speed data from a large
dish antenna to another radio tower 20 miles away . . . . . 1/8 watt to 2 watts
Power generated by the cavity magnetron in a
microwave oven and used to heat the meatloaf . . . . . . . 600 watts to 1,200 watts
do you want to know something? there is no radiation from a microwave oven. that was one of the biggest blunders in the history of home appliances when amana called the first microwave oven a radar range. the food in a microwave is not heated by radiation but by a magnetron which alters the cells in food from positive cells to negative cells back to positive etc. etc. this flipping of the cells creates friction which produces heat. now this is done on such a fast speed thatit can defrost a 1 inch steak in about 15 minutes at 50% power. also it cooks the meat from the inside out so the steak that lands on your plate is not attractive at all. hence in my experience the microwave is soley good for heating macaroni and tv dinners. and maybe water for tea.so relax, these microwaves cannot escape because if you look at the glass in the door you will see a lot of circles with spaces between them which allows you to see into the oven but the microwaves are larger than these holes and thus cannot escape. people with pacemakers aretold to not stand directly in front of the oven when heating as the magnetic force can play with their pacemakers. so if there is no radar there is no radar in your food
I have a hunch that when you say "a microwave", you're talking about the square
box in your kitchen that heats food fast.
The correct name for that appliance is a "microwave oven". It was given that name
because when it's turned on ... in the heating mode ... the chamber in it is filled with
high-power microwave radio waves. The food in the chamber absorbs some of that
microwave radiation, and becomes heated by it.
It certainly is. In exactly the same way that gamma rays, X-rays, yellow light,
orange light, sunshine, emissions from a cell phone, emissions from a flashlight,
emissions from a garage-door opener, AM radio signals, GPS signals, TV signals,
and emissions from a candle are examples of radiation.
Yes microwaves use radiation to heat up your food. Some people have even made a bomb with a microwave.
No.
Yes
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
You'd better clean it. There is a good chance it could be radioactive now.
Radioactive energy, basically the same thing that is used to make nuclear war heads.

Yes, micrwaves user radioactive engery which is bad for people as you can get cancer such as brain toumors. It is good not to use the microwave all the time and if you do stand a couple of feet awy from it.
No, radon is a naturally occurring radioactive element present in materials containing uranium and thorium (both of which are also radioactive). The most likely source of radon in a building is granite, either in the bedrock underground, in granite countertops and tabletops, granite fireplaces, etc. A microwave cooker is made of metal and plastics and contains no radioactive materials.
A microwave is, in fact, a microwave
No. Radioactive decay is the breakdown of the nucleus of an atom due to its instability. This may emit radiation in the form of gamma rays or subatomic particles. Microwave "radiation" is the name given to electromagnetic waves in a certain range of frequencies. It differs from gamma rays, x-rays, and visible light only in frequency and energy.
Microwave energy is already a usable power source for cooking/re-heating food.
