Electromagnetic radiation are vibrations from electric and magnetic fields. The speed of propagation in a vacuum is equal to the speed of light (about 300,000 km / s). In other environments, the speed of radiation propagation is less.
Electromagnetic radiation is classified by frequency range. The boundaries between ranges are very conditional, there are no sharp transitions in them.
Visible light. This is the narrowest range in the entire spectrum. A person can only perceive it. Visible light combines the colors of the rainbow: red, orange, yellow, green, blue and purple. Behind the red color is infrared radiation, behind the purple – ultraviolet, but they are no longer distinguishable by the human eye.
Visible light waves are very short with high-frequency’s. The length of such waves is one billionth of a meter or one billion nanometers. Visible light from the sun is a kind of cocktail in which three main colors are mixed: red, yellow and blue.
Ultraviolet radiation is part of the spectrum between visible light and x-rays. Ultraviolet radiation is used to create lighting effects on the stage of the theater, discos; banknotes of some countries contain protective elements that are visible only under ultraviolet light.
Infrared radiation is part of the spectrum between visible light and short radio waves. Infrared radiation is more heat than light: every heated solid or liquid body emits a continuous infrared spectrum. The higher the heating temperature, the shorter the wavelength and higher the radiation intensity.
X-ray waves have the property of passing through matter and not being absorbed too much. Visible light does not have this ability. Thanks to x-rays, some crystals can glow.
Gamma radiation is the shortest electromagnetic waves that pass through matter without absorption: they can overcome a one-meter wall of concrete and a lead barrier several centimeters thick.
IMPORTANT! It’s important to avoid x-ray and gamma radiation, as they represent a potential danger to humans.
Processes that occur in space and objects that are located there generate electromagnetic radiation. The wave scale is a method for registering electromagnetic radiation.
Power lines. At a distance of 10 meters, they pose a threat to human health, so they are placed at a high altitude or buried deep in the ground.
Electric transport. This includes electric cars, trains, subways, trams and trolleybuses, as well as elevators. The metro has the most harmful effect. It is better to move on foot or on your own transport.
Satellite system. Fortunately, strong radiation, when it hits the Earth's surface, dissipates, and only a small part of the danger reaches people.
Functional transmitters. radars and locators. They emit an electromagnetic field at a distance of 1 km, so all airports and weather stations are located as far away from cities as possible.

Radiation from household electrical appliances.** Widespread sources of electromagnetic radiation are household appliances that are located in our homes.
Mobile phone. The radiation from our smartphones does not exceed the established norms(according to some; this hasn’t been scientifically proven), but when we call someone, after dialing the number, the base station connects to the phone. At this point, the rate is greatly exceeded, so hold the phone to your ear not immediately, but a few seconds after dialing.
Computer. Radiation also does not exceed the norm, but for long-term work, it’s recommended that you take a break for 5-15 minutes every hour.
Microwave. The microwave enclosure provides radiation protection, but not 100%. Being near a microwave oven is dangerous: radiation penetrates under the skin of a person by 2 cm, triggering pathological processes. When using the microwave oven, keep a distance of 1-1. 5 meters from it.
TV. Modern plasma TV’s do not pose a great danger, but the old ones with kinescopes should be wary and stay at a distance of at least 1.5 m.
Hair Dryer. When a hair dryer is working, it creates an electromagnetic field of great strength. At this time, we dry our hair long enough and keep the hair dryer close to the head. To reduce the risk, use a hair dryer at least once a week. Drying your hair in the evening can cause insomnia.
Shaver. Instead, buy a regular machine, and if you are used to it – an electric shaver on a battery. This will significantly reduce the electromagnetic load on the body.
Chargers. Chargers create a field in all directions at a distance of 1 m. While charging your gadget, do not stay close to it, and after charging, disconnect the device from the outlet so that there is no radiation.
Electrical wiring and sockets. Cables that leave electrical panels are particularly dangerous. The distance from the cable to the bed must be at least 5 meters.
Energy saving lamps. Energy-saving lamps also emit electromagnetic waves. This applies to fluorescent and LED lamps. Install a halogen or incandescent lamp: they do not emit anything and do not pose a danger.
Every organ in our body vibrates. Thanks to vibration, an electromagnetic field is created around us, which contributes to the harmonious work of the entire body. When our bio-field is affected by other magnetic fields, it causes changes in it. Sometimes the body copes with the influence, sometimes-not. This becomes the cause of poor health.
Even a large crowd of people creates an electric charge in the atmosphere. It is impossible to be completely isolated from electromagnetic radiation. There is an acceptable level of EMI, which is better not to exceed.
Here are the safe health standards:
30-300 kHz, occurring at a field strength of 25 Volts per meter (V/m),
0.3-3 MHz, at a voltage of 15 V / m,
3-30 MHz-10 V/m voltage,
30-300 MHz-3 V/m voltage,
300 MHz-300 GHz-the voltage is 10 µw/cm2.
At these frequencies, gadgets, radio and television equipment work.
The nervous system is extremely sensitive to the influence of electromagnetic rays: nerve cells reduce their conductivity. As a result, memory deteriorates, and the sense of coordination is blunted.
When EMP affects a person, the immune system is not only suppressed – it begins to attack the body.
IMPORTANT! For pregnant women, electromagnetic radiation is particularly dangerous: the rate of fetal development decreases, defects in the formation of organs appear, and the probability of premature birth is high.
If you spend a lot of time at the computer, remember one rule: the distance between the face and the monitor should be about a meter.
The level of electromagnetic radiation of household appliances that you buy should not reach the "minimum" level, keep it as low as possible. Contact your sales consultant. They should be able to help you choose the safest products.
Your bed should not be located near the place where the electrical wiring is laid. Place the bed at the opposite end of the room.
Install a security screen on your computer. It is made in the form of a small metal mesh and acts on the Faraday principle: it absorbs all the radiation, protecting the user.
Reduce your time on electrified public transport. Give preference to walking, Cycling.
You can hire specialists to scan your home for radiation, they have special devices that allow them to get accurate radiation readings.
You can also buy your own radiation detection device. They work by detecting different frequencies and the voltage of the electromagnetic field. The device adjusts to the desired frequency mode by selecting units of measurement: volt / meter or microvatt / cm2, tracks the selected frequency and outputs the result to the computer.
A good device is the ATT-2592. It's portable and has a backlit display. The measurement is performed using an isotropic method, and is automatically switched off after 15 minutes.
