People use different electronic devices for information and to enjoy in their leisure time. This information is usually received in the form of spoken text, music or images. Compared with television, satellite receiver, communication by Morse code, mobile telephony, etc., Holds the least risk is listening to the common radio, battery powered and used with a telescopic antenna. It is characterized by low voltage electromagnetic field and a small and safe radiation to man. 
However, the listener takes a risk in certain circumstances due to which it must comply with certain safety standards. Otherwise would have been affected own listener, as well as receiver and antenna. Depending on their origin and incidence, the risks tend to be of three types: risk arising from the use of AC at home, risks from natural hazards and risks arising from the neglect subjective nature. The high voltage electrical conductors, 110, 220, 380 and more volts, should be located away from the antenna. When using power rectifiers, one must be careful with that part of the device it is the winding (coil) primary. If the receiver is in proximity to or on a metal surface is ground to do the same.
If a thunderstorm is the external antenna must be equipped with earth, and is not mounted on dead trees. In any case, they are not in practice listening, outdoor antenna should be grounded and be disconnected from the receiver input. Population centers in the alternating current of 220 volts or other voltage is carried by cables mounted on poles, to trigger a lightning storm is to go to listen to using a battery-powered receiver and disconnect only the rectifier electricity. There are other risks
more, as, for example, the consequences of use for a long time, instead of the headphone loudspeaker radio. Small earphones that are inserted into the ear damage the ear tissue and its various elements, such as the eardrum, and reduce hearing. They make it difficult brain activity and impair the person's mental state. The big headphones cause further accumulation of fatty tissue around the ears, which must be removed via operational.
In recent years, some radio stations have closed their programs on shortwave and medium, and replaced them by programming Internet. Listeners fond of this mode of reception have to know that personal computers and some auxiliary devices such as ADSL, generated around a magnetic field, while laptops and monitors generate X-ray radiation
For this reason you should stay no longer than 40 minutes in proximity to these devices, after which the listener must make a 20 minute break.
must also comply with safety recommendations contained in the instructions for the use of all electronic equipment, as is common practice in EU countries.
