How does electromagnetic radiation of electrical appliances affect a person?

Everyone knows that many appliances have a negative effect on health. This is especially true for devices with a wave principle of operation.

We all know that in addition to the visible benefits, many electrical appliances can imperceptibly harm human health. This primarily relates to devices based on the operation of which electromagnetic waves.

One of such devices is a microwave oven, which is a source of medium-frequency waves. The permissible radiation level of the furnace is 10 μW / cm2.

Usually at a distance of half a meter for all products this level corresponds. But it can increase due to improper transportation or factory defects. Waves can pass, for example, through the gap between the door of the stove and the body, so if, as a result of prolonged use, the door begins to lie loose, the device must be repaired or disposed of.

About the distance at which a person can be when the microwave is on, it is usually said in the instructions. As practice shows, the distance of one meter or more is quite enough.

The harm of a device such as a mobile phone is finally debating. The fact is that it belongs to new technologies, therefore, long-term observations are necessary to determine the harm.

Even the World Health Organization is limited to preventive policies, not recommending the use of telephones for pregnant women, children and people with diseases of the nervous system. Well, of course, just to reduce the time of conversations. However, even the figures speak for themselves: the permissible level of radiation from a mobile phone is 100 μW / cm2 (10 times higher than that of a microwave).

It is believed that if the phone was imported and sold legally, with documents, then its radiation level will be acceptable. But in some conditions, this level increases. For example, when the phone is in a weak reception area (in a transition, in a forest far from the station, in the basement), the radiation power automatically increases in order to avoid disconnection. Therefore, in such conditions, it is better to reduce the time of calls. The same applies to travel in transport, when the phone "breaks away" from one station and is "attached" to another.

As for home radiotelephones, their radiation level is even higher than that of mobile phones. And the base of such phones is not recommended to be installed in living rooms, especially bedrooms and children's rooms. After all, when the tube does not lie on the base, there is always a connection between them, and there may be a small level of radiation, but its effect on health has not yet been determined, so it’s better not to risk it. Just put the base in the hallway or at least in the kitchen.

You must be careful with old picture tubes. The recommended distance from which these devices can be viewed is 3-5 screen diagonals. That is, you need to watch a standard 54-cm TV from a distance of one and a half to two meters. And do not put these devices in small-sized rooms, as well as in children's rooms. And even better - replace them with modern plasma and liquid crystal devices, the radiation level of which is incomparably lower. The same goes for computer monitors.

By the way, almost all modern devices are recommended to be used from a network in which there is grounding. Therefore, it is best that the sockets are with grounding. And always carefully read the operating instructions, this will help you more safely and efficiently use electrical appliances, of which, of course, no one will be able to.
