	Microwave Oven
		But remember that the microwave oven can not do it all, a meal made solely in a microwave oven is no meal but a snack and should not be considered as anything else.
		The microwave oven did not become cheap and easy enough to be bought by the ordinary man until the late 80s and that is when the microwave oven boom spread across the globe, resulting in that the microwave oven today is a standard household appliance everywhere.
		The microwave oven uses the fact that water molecules among many other molecules are electric dipoles, meaning that they are not perfectly balanced when it comes to electrical charge having one negative side and one positive one.

	Microwave Oven
		The microwave oven was invented as an accidental by-product of war-time (World War 2) radar research using magnetrons (vacuum tubes that produce microwave radiation, a type of electromagnetic radiation that has a wavelength between 1 mm and 30 cm).
		An oven that heated food using microwave energy was then placed in a Boston restaurant for testing.
		Microwave ovens were a spin-off of wartime RADAR, and invented accidentally by Percy LeBaron Spencer of Raytheon while working on a magnetron (radar tube) near the end of the war.

	How Things Work - Microwave Ovens (Site not responding. Last check: 2007-10-19)
		Microwaves are transferred from the small antenna near the magnetron to the cooking chamber by sending those microwaves through a metal pipe.
		When the microwave oven is turned on, the microwaves not only heat the water in the grapes, they also push a few mobile electric charges back and forth through the skin bridge from one side of the grape to the other.
		Microwaves are not radioactive--radioactivity is the spontaneous fragmentation of the nuclei of atoms and is usually associated with the emission of high-energy particles; particles that can induce chemical changes in the molecules they encounter.

	Microwave oven - Wikipedia, the free encyclopedia
		A microwave oven, or microwave, is a kitchen appliance employing microwave radiation primarily to cook or heat food.
		Microwave ovens are capable of disrupting wireless network transmissions because the ovens generate radio waves of about 2450 MHz, near the 802.11b/g frequency band.
		Microwave ovens are frequently used for reheating previously cooked food, and bacterial contamination may not be killed by the reheating, resulting in foodborne illness.

	A Practical Approach to Microwave Oven Safety
		Most concerns about microwave oven safety are generated by employees who have accidentally damaged an oven, read a mass media article about electric and magnetic fields (EMF) dangers, or are suffering from some illness which they associate with exposure to an oven.
		Due to the inherent safety of microwave oven design, it may not be justifiable to expend the resources needed to measure the microwave leakage for all the ovens on your site.
		Although microwave oven safety is usually a small part of any nonionizing radiation safety program, it is a part that is highly visible because it potentially impacts so many people.

	Microwave oven health risk - cancer risk
		Microwaves are very short waves of electromagnetic energy that travel at the speed of light (186,282 miles per second).
		These documents, along with some working microwave ovens, were transferred to the United States War Department and classified for reference and "further scientific investigation." The Russians had also retrieved some microwave ovens and now have thorough research on their biological effects.
		Microwave oven radiation is present whenever a microwave oven is turned on.

	CDRH Consumer Information - Microwave Oven Radiation
		Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space.
		Microwaves have three characteristics that allow them to be used in cooking: they are reflected by metal; they pass through glass, paper, plastic, and similar materials; and they are absorbed by foods.
		Although heat is produced directly in the food, microwave ovens do not cook food from the "inside out." When thick foods are cooked, the outer layers are heated and cooked primarily by microwaves while the inside is cooked mainly by the conduction of heat from the hot outer layers.

	Office of Radiation Protection, Microwave Oven Radiation Safety - WA State Dept. of Health
		On the basis of current knowledge about microwave radiation, the Agency believes that ovens that meet the FDA standard and are used according to the manufacturer's instructions are safe for use.
		Although heat is produced directly in the food, microwave ovens do not cook food from the "inside out." When thick foods like roasts are cooked, the outer layers are heated and cooked primarily by microwaves while the inside is cooked mainly by the slower conduction of heat from the hot outer layers.
		Microwave cooking can be more energy efficient than conventional cooking because foods cook faster and the energy heats only the food, not the oven compartment.

	Hidden Hazards of Microwave Cooking (Site not responding. Last check: 2007-10-19)
		Microwaves are a form of electromagnetic energy, like light waves or radio waves, and occupy a part of the electromagnetic spectrum of power, or energy.
		Since it's currently published that microwaves - purportedly - don't leak into the environment, when properly used and with approved design, the decision lies with each consumer as to whether or not you choose to eat food heated by a microwave oven or even purchase one in the first place.
		Like most young adults at the time, as microwave ovens became commonplace, I chose to ignore my mother's intuitive wisdom and joined the majority who believed microwave cooking was far too convenient to ever believe anything could be wrong with it.

	Microwave Oven Radiations Hazards & Standards
		Microwaves cease to exist as soon as the power to the magnetron of a microwave oven is switched off.
		A positive feature of microwave ovens with regard to food safety is that food can be taken from the freezer, thawed quickly, cooked and served without it spending long periods of time in the danger temperature zone between 4°C and 60°C, which provides favorable conditions for the growth of dangerous micro-organisms.
		Microwave oven leakage detectors for household use should be purchased and their instructions followed carefully for an accurate result.

		Microwaves (short waves or high frequency radio waves) are the shortest of radio waves, with a length of 0.1 millimeter and a frequency of 3 x 10
		Microwaves are reflected from most metals but they produce inductive resonance's in the atoms of many other substances.
		Housed in refrigerator-sized cabinets, the first microwave ovens cost between $2,000 and $3,000 and were sold by Raytheon primarily to the commercial marketplace.

		The inside of the oven is where you put the meat to cook, roomy enough for a turkey or a lot of other things.
		First you season and marinate the meat,(overnite is best.) Put it in a pan with onions, carrots, potatoes, etc. Put the pan in the Microwave and build a fire with 8 to 10 lb.
