Microwave oven manufacturers are required to certify their products and meet safety performance standards created and enforced by the FDA to protect the public health.
Demystifying The Microwave
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. Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.
The human eye can only detect a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an X-ray machine uses yet another portion. Visible light, microwaves, and radio frequency RF radiation are forms of non-ionizing radiation.
Non-ionizing radiation does not have enough energy to knock electrons out of atoms. X-rays are a form of ionizing radiation. Exposure to ionizing radiation can alter atoms and molecules and cause damage to cells in organic matter.
Microwaves are used to detect speeding cars and to send telephone and television communications. Industry uses microwaves to dry and cure plywood, to cure rubber and resins, to raise bread and doughnuts, and to cook potato chips.
But the most common consumer use of microwave energy is in microwave ovens. 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.
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. That's why foods that are high in water content, like fresh vegetables, can be cooked more quickly than other foods. Although heat is produced directly in the food, microwave ovens do not cook food from the "inside out.
Microwave cooking can be more energy efficient than conventional cooking because foods cook faster and the energy heats only the food, not the whole oven compartment. Microwave cooking does not reduce the nutritional value of foods any more than conventional cooking. In fact, foods cooked in a microwave oven may keep more of their vitamins and minerals, because microwave ovens can cook more quickly and without adding water.
Glass, paper, ceramic, or plastic containers are used in microwave cooking because microwaves pass through these materials. Although such containers cannot be heated by microwaves, they can become hot from the heat of the food cooking inside. Some plastic containers should not be used in a microwave oven because they can be melted by the heat of the food inside. Generally, metal pans or aluminum foil should also not be used in a microwave oven, as the microwaves are reflected off these materials causing the food to cook unevenly and possibly damaging the oven.
The instructions that come with each microwave oven indicate the kinds of containers to use.Download gn exe
They also cover how to test containers to see whether or not they can be used in microwave ovens. The FDA received reports in the past of serious skin burns or scalding injuries around people's hands and faces as a result of hot water erupting out of a cup after it had been overheated in a microwave oven. Super-heated water water heated past its boiling temperature does not appear to be boiling and occurs when water is heated by itself in a clean cup.
If super-heating has occurred, a slight disturbance or movement such as picking up the cup, or pouring in a spoon full of instant coffee, may result in a violent eruption with the boiling water exploding out of the cup. Adding substances such as instant coffee or sugar before heating greatly reduces this risk.
Users should closely follow the precautions and recommendations provided in the microwave oven instruction manuals, specifically regarding heating times. Users should make sure that they do not exceed the recommended heating times when determining the best time settings to heat water to the desired temperature.If the fan, light, or turntable operates when the door is open, do not use the oven.
You can report the issue to the manufacturer or the FDA. Did you know the U. Food and Drug Administration regulates microwave ovens?Difference between ethiopian orthodox and catholic
Microwave oven manufacturers must certify their products meet safety performance standards created and enforced by the FDA to protect the public health. Microwave ovens are generally safe when used correctly.
But people have experienced burns, and in rare cases, other injuries from microwave radiation, particularly in cases involving improper use or maintenance. Therefore, always use your oven properly read on for tips and maintain it as recommended by the user manual. First, know that microwaves—the actual waves produced by these ovens—are a type of electromagnetic radiation. These waves cause water molecules in food to vibrate.
These vibrations, in turn, produce the heat that cooks food. The waves are produced by a vacuum tube within the oven called a magnetron. Microwaves are a kind of non-ionizing radiation. They do not have the same risks as x-rays or other types of ionizing radiation. Ionizing radiation is a more energetic type of radiation that can cause changes to human cells. Most injuries related to microwave ovens are the result of heat-related burns from hot containers, overheated foods, or exploding liquids.
Most injuries do not relate to radiation. That said, there have been very rare instances of radiation injury due to unusual circumstances or improper servicing. In general, these radiation injuries are caused by exposure to large amounts of microwave radiation leaking through openings such as gaps in the microwave oven seals. However, FDA regulations require that microwave ovens are designed to prevent these high-level radiation leaks.
In fact, manufacturers must certify that their microwave ovens comply with specific FDA safety standards. These standards require any radiation given off by ovens to be well below the level known to cause injury. You can consult with your health care provider if you still have concerns. Directions in the user manual provide recommended operating procedures and safety precautions.
For instance, you should not use some microwave ovens when they are empty. Use microwave-safe containers. Use cookware specially manufactured for use in the microwave oven. Generally, you should not use metal pans or aluminum foil because microwaves reflect off them, causing food to cook unevenly and possibly damaging the oven. And you should not use some plastic containers because heated food can cause them to melt.
The FDA recommends using glass, ceramic, and plastic containers labeled for microwave oven use. Avoid super-heated water. If you use a microwave oven to heat water in a clean cup beyond the boiling temperature, a slight disturbance or movement may cause the water to violently explode out of the cup. Adding ingredients such as instant coffee or sugar to water before heating greatly reduces the risk of hot-water eruption.Do you think your microwave oven is harmful to your health?

But while you zap your food, you may wonder how close you can safely stand next to a microwave, and whether any radiation could escape from the device and potentially harm you.
Do you really need to worry about this? The short answer is, not really. Injuries from microwave radiation are very rare, according to the U. Food and Drug Administration. However, there are certain precautions you can take to keep yourself safe when using a microwave oven. Microwaves are a type of electromagnetic radiationor waves of energy that move through space, according to the FDA.
Electromagnetic radiation takes different forms, including radio waves, visible light, X-rays and gamma-rays. In contrast, X-rays and gamma-rays are classified as "ionizing radiation," a type that does have enough energy to remove electrons from atoms and can damage cells and DNA. Even though microwaves don't pose the same health risks as X-rays, that doesn't mean they are risk-free. Microwaves heat food by causing water molecules to vibrate, which produces heat.
In theory, microwaves can heat body tissues in the same way they heat food, and at high levels, microwaves can cause burns and cataractsaccording to the FDA. But these types of injuries are very rare and have generally occurred when people are exposed to large amounts of radiation leaking through openings in the oven, such as gaps in the seal, the FDA says.
What's more, the FDA requires microwaves to be designed in a certain way to prevent these types of radiation leaks. For example, the FDA requires that microwave ovens have two interlock systems that halt the production of microwaves the moment the door is opened.
And the agency requires that these ovens have a monitoring system that stops the device from operating if one of the interlock systems fail. As a result, there is "little cause for concern" about excess microwaves leaking out from your oven, unless there is damage to the door hinge, latch or seal, the FDA says. Still, the agency recommends that you check your microwave oven carefully and do not use it if the door doesn't close properly, or if it is "bent, warped, or otherwise damaged.
As far as injuries from microwave ovens go, the most common way people are injured is via heat-related burns from touching hot containers or overheated foods, or being exposed to exploding liquids. The FDA recommends that people use common-sense precautions when handling hot foods and beverages cooked in microwave ovens. The agency also warns that, when you use a microwave to heat water in a cup, there's a risk of the water becoming " superheated ," which means it has heated past its boiling point.
When this happens, the water does not appear to be boiling, but just a slight disturbance to the water — which can occur when touching or picking up the cup — can cause an eruption of boiling water.Heat has beneficial and damaging effects on food. But is microwaved food worse for you than conventionally cooked food? There is very little hard, scientific evidence that this is so, although there is plenty of internet legend about this topic. For example, it is claimed that if you water a plant with microwaved water, the plant will die — apparently based on a science experiment conducted by a schoolgirl using just two plants, in which one plant was watered with microwaved water — and died.
Microwave Oven Radiation
This claim is repeated so often on the internet that it can be hard to believe that it is not a verified, scientific fact. As with any method of cooking, there are pros and cons of microwaving. With some foods, more of certain nutrients may be lost by microwaving than by using other cooking methods. And whichever method you use, it is important to cook the food enough to destroy pathogens and parasites but not too much. For example, when cooking vegetables, it is possible to microwave them in very little water, which also helps to minimise nutrient loss and shorten cooking time.
Actually, nutrient loss is least when steaming vegetables — that is the ideal way to cook them! If any foods would be susceptible to damage by microwave heating, it would most likely be proteins.
Their complex molecular structures can be changed when heated, so beneficial protein molecules in food can become less useful. But this is not because of denatured proteins.
Now what about outside? Although the microwave radiation is screened by the frame of the oven, including the meshed glass door, practically all microwave ovens leak microwave radiation, even when they are brand new, and in perfect working order. This can be confirmed by anyone who has a radio-frequency EMF meter. When living on a large property, I could stand in the garden with my radio-frequency EMF meter and detect the moment the microwave oven inside the kitchen about feet away was switched on or off.
This is normal for microwave ovens. Hopefully, your microwave oven does not come close to this legal limit, which is already over a thousand times times higher than the level which many authorities would consider to be safe for long-term exposure! Nevertheless, it is a very bad idea to watch the microwave oven at work by peering in the glass door while it defrosts the Sunday roast or cooks the family meal.
So keep your distance while the microwave is busy. For greater safety, keep a distance of 1. A microwave oven can become very unsafe if the door is not latching properly or if any of the structure is damaged.Microwave Radiation
In such conditions, the screening of the microwaves might be ineffective and radiation many times stronger than the legal limit could be emitted.
If the door switch is working correctly, a microwave oven is completely safe once the door has been opened. The magnetron stops instantly and there is no residual microwave energy left in the food or the oven, only heat.Do you think your microwave oven is harmful to your health?

Now that you know microwaves are safe, are you planning to buy one?Nearly every modern kitchen has a microwave oven. Since the first domestic Radar Range microwave was introducedpeople around the world have been heating up their leftovers, popping their popcorn, and steaming their veggies with the appliance. Jorgensen and John Drengenberg, consumer safety director at Underwrites Laboratories ULclear the misconceptions, point out the more prevalent hazards, and share tips on how to avoid dangerous mishaps with microwave ovens.
One of the most common fears around microwave ovens is radiophobia, or fear of radiation. Jorgensen says that this may be partially due to the fact that the oven produces a man-made type of radiation, said Jorgensen.
The world of radiation, Jorgensen further explained, can be divided into two categories: non-ionizing and ionizing.Codility bug fixing questions
Scientists used to think so. On the electromagnetic spectrum, ionizing radiation has short wavelengths. The shorter the wavelength, the higher the energy. X-rays, for example, can have wavelengths that are one hundredth of the width of a human hair.
Under certain doses and levels of exposure, ionizing radiation could break apart molecules in our body, such as DNA. However, microwaves fall under non-ionizing radiation, which have much longer wavelengths. If you leave food in the microwave oven for too long, or contents are drying out or boiling over, the nutrition value could decrease.
However, you can also make food too hot in an oven or on a grill, Jorgensen pointed out. Try no-heat cooking. On the other hand, metals will block the microwaves. Additionally, metal handles on carton take-out boxes, twist ties, and aluminum foil can also create sparks if they graze the sides of the cavity. Sometimes, metals can be hidden from view, so Drengenberg cautions using certain seemingly innocuous items.
A nice set of plates could have a gold or silver trim, and recycled paper plates may have little bits of metal from reconstituted paper, Drengenberg explained. According to the National Fire Protection Associationthere is an average of 6, fires caused by microwave ovens, with civilian injuries based on to annual average data.
