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

What kind of radiation is given off by microwave ovens?

Microwave ovens emit non-ionizing radiation in the form of microwaves. This radiation heats the water molecules in food, causing them to vibrate and generate heat, which cooks the food. Microwaves are considered safe for use in kitchen appliances.


What type of energy does a microwave oven give off?

A microwave oven gives off electromagnetic radiation in the form of microwaves. These microwaves are used to heat and cook food quickly and efficiently.


Does a microwave give off thermal or radiation energy?

A microwave oven incorporates a microwave generator which produces EM energy at the right wavelength or frequency to energise water molecules in the food being cooked, which produces thermal energy in the food. The microwaves don't escape from the oven because they don't penetrate the materials the enclosure is made from. (EM = electromagnetic)


Does a microwave give off radiation?

All microwaves (the appliances) give off a small amount of radiation when they areoperating normally. This is due to tiny amounts of leakage, primarily at the door seal.This tiny amount of radiation is generally harmless, and as long as the microwave ovenis not "thrashed" and is kept in good repair, it will perform normally and leak only theslightest amount of energy.If any consumer is concerned with microwave radiation doing anything negative, thatindividual would benefit more from giving up his/her cellular phone than from giving upthe microwave oven.

Are microwave ovens the same as microwaves?

A microwave is a form of electromagnetic radiation in the frequency range between 300 MHz (or 0.3 GHz) and 300 GHz. A microwave is also the "shorthand" name we give to a common appliance called a microwave oven. Are they the same?Whether or not microwave ovens are the same as microwaves depends on the application of the term. Microwave ovens are called that because they contain a microwave generating device and direct the radiated electromagnetic energy (the microwaves themselves) into a cooking space (called a cavity) to heat drinks or food, or even to cook things.Say an appliance salesman is saying to his/her junior helpers, "Arrange the microwaves on the shelves." This refers to the microwave ovens. It's not about electromagnetic energy called microwaves.Take the case of an electronics teacher saying to his/her students, "The microwaves are reflected off the metal screen that is used in the construction of the dish." This does notrefer to microwave ovens, but the electromagnetic energy itself.


How much electricity does a microwave give off?

A microwave does not give off electricity.


How much radiation does a microwave give off what And can this be dangerous?

A microwave releases only micro waves. It doesn't release any harmful radiation. The only harm a microwave can cause is if you put certain items that can make it explode (like a lava lamp, dont try that please).


Can you keep a fish bowl on top of a microwave?

Microwaves give off well, microwaves and electromagnetic radiation; the waves may affect your fish's health.

How many millirems does a microwave give off?

Milli rems is a unit of X-ray radiation. Microwaves oven works by emitting electromagnetic waves using strong radiation, through a powerful transformer.


Why would one's microwave cause their cable modem to reset and not come back up until the microwave is turned off?

This does not sound like a problem with your cable modem (unless it is integrated with a router), but with your wireless router. Microwave ovens emit radio waves in the gigahertz range. These waves interfere with the transmission of the wireless router on the 2.4 GHz or 5 Ghz range. There is little that you can do about it, except relocating the microwave oven or router and computer. == Addition: Household microwave ovens typically use 2.45 GHz radiation, which means it matches pretty well. However, the radiation from a microwave should not, or barely, leave the oven at all. So either you have your router within, say, 1 meter of your router (in which case you should move either), OR your microwave is broken, in which case you should replace it.


Does a magnetron give off radio waves?

A magnetron may be used to generate radio-frequency currents and fields at high power and high frequencies. The source of RF in most microwave ovens is a magnetron.


Does iPhone4 give off radiation?
