The microwave is almost in each house today. It is the convenient device allowing to warm quickly, and sometimes and to cook food. Many use this device and at work, warming the dishes brought with themselves. At the same time there is quite popular belief that the radiation by means of which the device warms food for so short time has an adverse effect on our health. Whether so it? Whether it is valid in the microwave to prepare harmfully?
The microwave influences products by means of the range of ultrahigh frequencies (microwave oven) including centimetric and millimetric radio waves. Such radiation is something average between light beams and usual radio waves and has properties of both that, and another. In electrical household appliances the microwave radiation is applied to heat treatment of various products. The fast effect is reached thanks to the fact that the energy created by quite powerful sources concentrates in limited space.
The principle of action such is. The special element - the magnetron is installed in Microwave ovens. He creates from the electric power the superfrequency field influencing the water molecules which are contained in food, and forcing them to rotate with a huge speed and to create thereby friction at the molecular level. As a result of this process food heats up in a short time.
There is an opinion that as a result of such influence the molecular structure of products changes. According to the statements of opponents of microwaves among which there are also scientists the use of such food leads to decrease in pulse, arterial blood pressure, headaches, nervousness, sleep disorders, indigestions and a set of other negative consequences, up to formation of cancer cells.
Actually microwave waves are insufficiently strong to lead to such consequences. All that is described by opponents of microwaves can happen unless as a result of strong influence of x-ray or other ionizing beams. It is called radiation sickness and can be a consequence, for example, of nuclear radiation. To the microwave to such effect very far, and in time while food is exposed to a warming up, nothing critical happens to it to Consider that the microwave is a small nuclear reactor at your place or at office, it isn't necessary.
At the same time arguments that the radiation of the microwave oven isn't absolutely safe, not groundlessly. It is proved that work of electromagnetic systems influences a human body. However it is necessary to take into account intensity of such influence which at the serviceable Microwave oven working with the closed door, as a rule, not above than at the mobile phone which we carry with ourselves and privlkdyvay to the head everywhere during the conversation. What to tell about stay near high-voltage power lines!
Modern microwaves reliably protect the owners from penetration of microwave beams outside. They work only at the closed door, are equipped with a protective grid screen. The most probable cause for which the food warmed or prepared in such device can become junk - unwillingness of the user to regularly clean it inside. non-compliance with hygiene can lead to accumulation of hazardous substances.
