Does radiation affect pregnant women?

Conforming to national standards of microwave ovens qualified products leak radiation within the normal range, will not cause harm to the human body. To 1 milliwatt leakage to calculate, from the microwave oven 1 meter away from the space, microwave down to 0.0001 milliwatts. However, pregnant women should try to avoid the use of microwave ovens, compared to adults, the fetus and infants are more susceptible to radiation.

When the microwave oven is turned on, people should stay away from the microwave oven or at least 1 meter away from the microwave oven.

Extended information

A microwave oven does produce radiation, but it is harmless to the human body

The microwave oven is the formation of an orderly spatial electron flow through the radiated electrons that it produces, and the control of the electron flow with the use of magnetic fields through the electronic flow, controlled by the magnetic field and the geometry of the given environment. Under the magnetic field control and a given geometric environment to produce alternating electron flow, and then through the waveguide to make the alternating electron flow into the food processing area.

The alternating electron flow will stimulate the water molecules in the polarized food to produce alternating motion so as to generate heat, the water and then the heat generated by the transfer to the food, will be cooked. This shows that microwave ovens do emit radiation.

However, the microwave oven in the electromagnetic field only on the food in the water play a role, it is in a closed environment on the outside world's influence is very small, the production of regular manufacturers, with the 3C mark of the microwave oven are safe, will not have a harmful effect on the human body, not to mention damage to the brain.

Two, microwave heating will not make the loss of nutrients

Compared to other heating methods, the microwave heating efficiency is the highest, its thermal efficiency of up to more than 80%, the heating speed is very fast, the other heating methods of the thermal efficiency of only 30% -50% or so, so microwave on the destruction of food nutrients instead of small.

That is to say, compared to other heating methods, heating with a microwave oven instead of good.

Three, microwave-heated food is less likely to produce cancerous substances

The main medium of microwave heating is water, and the principle of heating is the molecular oscillation of the water in the food, which produces heat. Therefore, it is not possible to produce something new.

Of course, if the food is burnt or scorched when heated by microwave, it is possible to produce harmful substances. But that's attributed to the burning and scorching and has nothing to do with the heating method.

Four, the use of microwave oven taboo

1. Avoid heating the meat to half-cooked and then use the microwave oven to heat

Because in the half-cooked food in the bacterial growth will still be the second time with the microwave oven when heated, due to the short period of time, it is not possible to kill all the bacteria. Frozen meat should be thawed in the microwave first and then reheated as cooked food.

2. Avoid refreezing

The meat thawed by the microwave oven because the meat thawed in the microwave oven, in fact, has been outside a layer of low-temperature heating, the bacteria can reproduce at this temperature, although the refreezing can be made to reproduce to stop, but can not be killed by the living bacteria. If the meat has been defrosted in the microwave oven and then put into the refrigerator, it must be heated until it is fully cooked.

3. Avoid frying food

Because of the high temperature of the oil will be splattered and lead to fire. If inadvertently caused by the stove fire, do not open the door, but should first turn off the power, to be extinguished after the fire and then open the door to cool down.

4. Avoid overtime heating

Food into the microwave oven defrosting or heating, if you forget to take out, if the time is more than 2 hours, should be thrown away, so as not to cause food poisoning.

5. Avoid using ordinary plastic containers

Use a special microwave oven utensils to contain food into the microwave oven to heat, a hot food will make the plastic containers deformed, and the second is the ordinary plastic will be released toxic substances, contaminated food, endangering human health.

6. Avoid using metal utensils

Because the furnace into the iron, aluminum, stainless steel, enamel and other utensils, the microwave oven in the heating will produce sparks and reflect microwaves, both damage to the furnace body and heat the food is not cooked.

7. Avoid the use of closed containers

Heating liquids should be used wide-mouth containers, because the heat generated by the heating of food in closed containers is not easy to disseminate, so that the pressure inside the container is too high, prone to cause blasting accidents. Even when frying food with shells, we should use a needle or chopsticks to puncture the shell beforehand, so as not to cause bursting after heating, splashing dirty stove wall, or splash injury.

8. Avoid placing the microwave oven in the bedroom

At the same time, care should be taken not to cover the microwave oven with items on the cooling grate.
