Microwave: destroying myths and misconceptions about the dangers of

Microwave - an indispensable tool for rapid heating or thawing of a product. But there is a perception that the microwave is nothing else as the most dangerous power tool, which is designed to reduce the population. Together, let us look at the most common myths and examine what actually harmful microwave oven. So, let's begin.

How does the microwave

In order to make it all clear to begin with a brief rundown on the principle of work. Microwave oven - is a device in which the heating of the food as a result of exposure to the electromagnetic radiation in the decimeter range.

The source of radiation is a magnetron which is powered by a high voltage transformer. The radiation frequency magnetron in most cases is 2450 MHz. This frequency is allocated specifically for household appliances of the Federal Communications Commission in 1945.

Thus, the radiation emitted a magnetron into the inner chamber of the microwave oven, food is heated and placed inside so:

UHF radiation has an effect on polar molecules (plain water). External action causes the molecules that originally were at rest, vibrate at a frequency of 2450 MHz. It turns out that the molecule as if rubbing against each other, and heat is generated as a result of friction - the food is heated. This, of course, very approximate and simplistic explanation of the principle of heat, but it should be sufficient for further understanding.

Now let's move on to the myths

Radiation breaks down the molecular structure

The first and perhaps the most common myth stems from the fact that the emitted radiation is literally breaks molecules and thereby changes the physical structure of the product and there is so-called an isometry (reorientation molecules). So we remember from school lessons, what isomer.

So, isomers - is the existence in nature of so-called isomers with the same composition and molecular weight but different in structure and properties.

We have found that microwave radiation acts on the molecules of water and the water - it is an amorphous body, which in principle has no structure (except for the crystalline form - ice). That is how you can change what is not.

When this occurs only what will happen with any method of heating: cleavage of complex organic compounds to simpler, thereby improving the digestibility of food.

But in one advocates harm right after the microwave food is not the same, it's hot.

Microwave "fonit" as nuclear reactor

There is a myth that microwaves even when switched off is the source of radiation.

all just here. Leave behind residual radiation can only gamma radiation of a wavelength less than 3 pm and the wavelength of the microwave is equal to 12 cm. That is, it can not physically be the source of radiation.

Microwave created Nazis

On the Internet go tales that the microwave was created in Germany by engineers for heating food to soldiers, but further clinical trials showed extremely negative consequences for the human body, and after similar tests of the USSR and a number of others have prohibited the eastern countries Microwave oven.

Curiously, this prohibition does not extend to the first Soviet microwaves, such as: "Dnepryanka - 1", "Dnepryanka -2", "Zil", "Mrija CF", "Electronics", which began to produce 80-e.

But the patent was obtained by American engineer P. Spencer in 1946. And the first microwave oven was released in 1947 by Raytheon and was intended for defrosting food.

The tests

Also in the wide area network is often referred to this experiment with a group of volunteers from the United States, which did eat the "healthy foods" and foods, heat from the microwave. In this study group consisted of 16 people, divided in half.

So, according to the results of the experiment it was allegedly established that the group eating microwaved, showed a clear deterioration of the general state of health. Of course, there are no accurate figures and calculations are given.

These alleged studies looks at least strange, and here's why: the research group is too small, not shown the initial data on the state of health of the subjects, and after the experiment (only general conclusions) are not specified the timing of experiment.

To talk about the harm to health, we need a deeper and more thorough study.

What's the real harm from the microwave

Of course, I do not want to say that the microwave - this is the perfect product without flaws. She has a very serious drawback, and it is an electromagnetic field which is formed around the product during operation.

Safe level of microwave radiation is not more than 10 mW / sm.kv.

And the door itself will be equal to the level of radiation of 5 mW / sm.kv.. That's a lot, but just at a distance of half a meter the radiation intensity decreases by half, and at a distance of 1.5 meters from a working microwave radiation is below the marginal rate by half.

So, to reduce the negative impact of electromagnetic fields at microwave heating of food are at a distance of one meter, and everything will be fine.

conclusion

Microwave - is an essential part of most modern kitchens and most of the myths about the harm it untenable, but the harm from its Use all the same there, and to be reduced to a minimum, carefully read the instructions and follow all recommendations, and will all OK.
