  • Microwave ovens - good and bad

    click fraud protection

    During the whole existence of microwaves, on the Internet and not only there has been a huge amount of controversy about whether there is harm or benefit from the microwave oven. Why do such questions arise: simply because everywhere it is discussed or the microwave is still so harmful to humans? Most likely, the first option is more correct. People began to think about how to stay healthy more often. Because of this, there was a fashion to discuss objects and products that could harm health( preservatives, GMOs and microwave ovens).

    Operating principle of the

    It is based on the action of a powerful magnetron, which converts ordinary electricity into an electric field with an ultra-high frequency of 2450 MHz. Thus, special microwaves can influence water molecules in food so that they begin to fluctuate with the superfrequency and it is thanks to this that the process of heating the product takes place.

    Due to the fact that the inner shell of the furnace is made of metal, the microwaves are reflected and their subsequent impact on the food from all sides.

    Microwaves can only appear if the microwave door is closed tightly. This is how the protection of a person from harmful radiation takes place: a door is closed, which is covered with a special protective film, which means that there will be no harm to the body.

    Stoving oven: benefit and harm

    Energy that gets into food when it is heated and cooked, completely turns into heat energy. And according to all the laws of physics - there is simply no more energy in the products.

    Of course, we are talking about cooking in a fully serviceable device, which has a door and a protective glass. But if your furnace has even the slightest cracks, when turned on, microwaves can go beyond the microwave. And such stoves are already really hurting their owners.

    The door on the microwave is absolutely sealed and does not let microwaves through. But small gaps around the door can be a source of minor radiation. Therefore, when preparing or warming up something in your oven, do not stand at the end of the appliance. This is especially true for pregnant women and children.

    It is best( if possible) to choose microwaves of known brands: large manufacturers, struggling with competition in the market, improve their products, monitor the level of radiation from the microwave oven and ensure that all parameters of the device meet the necessary standards of health in the world.

    Opponents of microwave ovens believe that food prepared in such a device can contribute to the onset of cancer, negatively affect the thyroid gland and adrenal glands. There are also people who claim that the use of microwaves by mothers affects the level of physical defects in their children.

    And to prove who is to blame, and who is right - it is impossible. After all over the past few years, there has not been a single major study of this issue. The last of the experiments in this area took place in the 80's and 90's.

    Questions and Answers

    There is a certain list of issues that are most often discussed by specialists:

    1. Does the microwave oven affect the molecular structure of food? And does it make it harmful to the human body?
      The answer is: microwaves, on which "all sins" are hung up, are too weak to change the structure of the product. To make this happen, you have to take at least an X-ray or other ionizing radiation. It is important to always pay attention to the dishes that you use in the microwave oven. It must necessarily be marked that it can be used in a microwave oven. But if a bright plastic plate gets under the action of microwaves, food can actually become a poison.

    2. Harm microwave can occur even if a person just goes to her? According to scientists, microwaves are not ionizing, so they do not do much harm to the body. In terms of human exposure, they are equated with a mobile phone( about the harm of which for some reason they say much less).In addition, the rays of the stove, in contrast to radiation, for example, are quite simple to stop. And in this sense, microwave is even harmless than a mobile phone, because in it at least there is a protective casing and a mesh on the door of the stove. And what does a mobile phone have?

    3. Can other household appliances be damaged if you keep the microwave turned on for a long time? A well-made oven does not emit harmful radiation outside its enclosure, so there is no danger at all. But still, the sealing surfaces between the oven and the door may become dirty. Determine that while the microwave is working on it emits radiation, it is possible by focusing on the radio and TV.

    4. A metal dish placed in a microwave can trigger a powerful explosion? It has already been said that microwave ovens are too weak for this to happen. The maximum that a discharge from a metal and a metal object in the microwave can do is to damage the emitter of the latter. And then you have to carry it to repair, or buy new equipment. No explosion is out of the question.

    Caring for the microwave

    Will there be this device in his house, each person should decide for himself. It is worth saying that the benefits of a microwave oven are not so small: what is one convenience of heating products. But, for those who still decided to get a microwave oven, one should listen to such advice:

    • it is necessary to install the oven on a horizontal surface that rises above the floor by at least 90 cm, with a distance from the walls of about 10-15 cm.turning the oven, you need to set it so that there is a distance from the oven to the edge of the table( 10 cm).
    • if there are openings for ventilation on the microwave, it is absolutely necessary to provide them with air access. And do not place the appliance next to the refrigerator, even if there is at least 40 cm between them.
    • never turn on the oven if there is nothing in it! So you just damage the device. Do not put in it a product whose weight is less than 200 grams. If you want to warm up a sandwich, put a glass of water with it in the oven.
