Is a microwave radioactive

Answer 1

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.

Answer 2

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food, this ban was revoked in 1976 when Russia changed to a free market after the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

Answer 3

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

Answer 4

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.

Answer 5

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.

Answer 6

Yes microwaves use radiation to heat up your food. Some people have even made a bomb with a microwave.

Answer 7

No.

Answer 8

Yes
