How to measure electromagnetic radiation

In our life we are surrounded with electromagnetic waves from all directions. They are radiated not only by our household appliances, computers, towers of radio - and telecasts, but even our planet has background electromagnetic radiation. As a rule, we face neoniziruyushchy electromagnetic radiation – radio waves, infrared, optical and ultra-violet. So light is electromagnetic radiation too. Besides, x-ray and scale radiation treat electromagnetic too.

It is required to you

  • ordinary radio receiver, indicator screw-driver, manual analyzer of tension of the electromagnetic field.

Instruction

1. From make-shifts best "catcher" of electromagnetic radiation is the ordinary radio receiver, something from the cheapest models is the best of all. They best of all react to electromagnetic aimings. Fasten a loop from a wire or a wire to the antenna of such receiver (radius not less than 20 centimeters), reconstruct radio on the frequency where there is no broadcasting and walk on the house, listen as the sound changes. Where distortions of a sound are most clearly heard, there electromagnetic radiation is stronger.

2. It is possible to try to make process of detection of strong electromagnetic fields by more evident. You go to large shop of radio electronics and ask the indicator screw-driver there. There are two types of such screw-drivers, take that which the light-emitting diode and three small batteries is built in. Usually they burn with red. At home bring such screw-driver to any switched-on device, carry out along wires (even if they are built in in a wall) – the more intensively light from the screw-driver, the electromagnetic radiation is stronger.

3. As it is impossible to measure electromagnetic radiation in figures by make-shifts, special devices are used. If your acquaintances work in the organizations for labor protection, certification or in service of Gossanepidnadzor, it is possible to try to ask for them the special device which will show you tension of the electromagnetic field. It is called the manual analyzer of tension of the electromagnetic field. The device is capable to measure the level of electromagnetic radiations of the most widespread frequencies. Turn on the device and transfer to the mode of tracking frequencies necessary to you. As it is at the same time impossible to monitor all indications, activate the mode of record of results of measurements, then look at them on the computer. Also adjust radiation units of measure independently – from habitual "volts on meter" to "microwatts on centimeter square".
