【Microwave Ovens】--- 微波炉
This page describes the type of electromagnetic radiation emitted by microwave ovens.
---------------------------------------------------------------------------
【Overview】
Heating up leftovers, popping popcorn for a movie, and making a steaming cup of hot chocolate are all made easy by using a microwave oven. Not only does food cook fast, but cooking with microwave ovens can be more energy efficient than conventional cooking because the energy heats only the food, not the whole oven compartment. Microwave ovens are electrically operated ovens using high-frequency electromagnetic waves that penetrate food, causing its molecules to vibrate and generate heat within the food to cook it very quickly.
Microwaves are a form of electromagnetic radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation ranges from the energetic x-rays to the less energetic radio-frequency waves (or RF waves) used in broadcasting. Microwaves fall into the RF band of electromagnetic radiation. They 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；
They are absorbed by foods.
Microwaves are produced inside the oven by an electron tube called a magnetron. The microwaves are reflected within the metal interior of the oven where they are absorbed by food. Microwaves cause water molecules in food to vibrate, producing heat that cooks the food. The microwave energy is changed to heat as it is absorbed by food. This does not make food radioactive or contaminated.
【Remember】
The microwave energy does not make food radioactive.
The Food and Drug Administration’s (FDA) Center for Devices and Radiological Health (CDRH) says that a person can be exposed to radiation if a microwave oven does not totally seal. Research is being done on the potential health effects from microwave exposure. It is known that microwave radiation can heat body tissue the same way it heats food. The type of heat injuries from microwave radiation can only be caused by exposure to large amounts of microwave radiation, much more than you would get from a household microwave.
Microwave radiation leakage is difficult to detect because you can’t smell or see it. Old or faulty door seals are the most common causes of microwave radiation leakage. Routinely slamming the door, a build-up of dirt, or simple wear and tear of continued use can cause door seals to be less effective. Due to door leakage, it is advised by the FDA to not stand directly in front or up against the oven while it is operating.

----- Who is protecting you？
U.S. Food and Drug Administration (FDA)
FDA’s Center for Devices and Radiological Health (CDRH) sets and enforces standards of performance for electronic products to assure that radiation emissions do not pose a hazard to public health. Theses standards can be viewed on the FDA’s Code of Federal Regulations on Microwave Ovens.
The FDA establishes performance standards for microwave ovens. All microwave ovens must have a label stating that they meet these performance standards. In addition, the FDA requires that all ovens have a label explaining precautions for use. To make sure the standard is met, the FDA tests microwave ovens at commercial establishments, locations of dealers and distributors, manufacturing plants, and its own laboratories. Evaluations of manufacturers\' radiation testing and quality control programs are also inspected by the FDA.
---------------------------------------------------------------------------
----- What you can do to protect yourself ？
The best way to protect yourself from microwave oven radiation is to comply with the following safety tips:
Follow the manufacturer\'s instruction manual for recommended operating procedures and safety precautions for your oven model.
Don\'t operate an oven if the door does not close firmly or is bent, warped, or otherwise damaged.
Never operate an oven if you have reason to believe it will continue to operate with the door open.
As an added safety precaution, don\'t stand directly against an oven (and don\'t allow children to do this) for long periods of time while it is operating.
Users should not heat water or liquids in the microwave oven for excessive amounts of time.

《立即將微波炉丟弃》------
在醫院中輸血，需將從冰箱拿出的血加以溫熱才可輸入人體，曾有護士為了急救病人節省時間，使用微波爐加溫血液，一輸入體後病人立即死亡，以後醫院中嚴格規定，絕不可用微波爐去溫熱血液。
專門調製給嬰兒服用的奶粉，盒上說明文字，明白寫出絕不可用微波爐去煮熱，因為它會破壞所有的營養。
有關微波爐所引起的各式傷害，蘇聯人作了許多研究，例如：
(a) 肉類微波後會產生一種致癌物 d-NitroSodienthanolanines。
(b)微波過的牛奶、水果、麥片，會將其中的氨基酸轉化為致癌物。
(c)蔬菜微波後，會將植物生物鹼（Plant Alkaloids）轉化成致癌物。
在蘇聯、德國、瑞士等國家，對微波爐造成人體傷害方面，作了許多研究。發現有許多負面的結論：
(01)它破壞腦組織。腦的傳播是靠磁波，微波爐處理過的食物，如長期食用，會中和腦磁波，使腦退化，磁波短路，此為長期副作用。
(02)微波爐食物，除了有致癌物之外，它還產生一堆不能為身體所吸收利用的不知名副產品。
(03)長期食用微波爐食物，使男女荷爾蒙分泌量減低或改變。
(04)微波爐食物的副產品，是長期而永久性的殘存於人體內。
(05)食物中礦物質，維生素及營養大量減少，或改變成致癌物，以及許多不能為身體所分解的合成物。
(06)微波爐烹煮的食物，使蔬菜中的礦物質，改變成會破壞人體的自由基。
(07)微波爐食物能引起胃癌，有些胃癌及腸癌，皆與吃太多微波爐食物有關。 這或許解釋了何以美國人近些年來，患直腸癌的比例如此迅速增加。
(08)長期吃微波爐食物，易使身體產生大量癌細胞。
(09)長期攝取微波爐食物，由於其中營養已被破壞，將使身體免疫系統出問題。
(10)這樣的食物，終將使記憶退化，精神不集中，情緒不穩定，且理解力降低。
您怎麼辦呢？
不要用『微波爐加熱或烹煮的食物』，才是最佳妙方！為了預防自己受癌症折磨，及為了家人及親朋好友的關切與善意，
請立即停止使用微波爐加熱或烹煮的食物。
