What exactly is radiation? Are each of us a source of radiation?

Radiation is actually a concept in physics, and it is actually a form of energy, and energy is transmitted to the human body in the form of waves or subatomic particles. And people can actually emit radiation because their body temperature is very high, so they can produce radiation. Everyone can be a source of radiation, and objects in nature are capable of producing radiation.

The general type of radiation is divided into two kinds of radiation, the first kind of radiation is ionizing radiation, this kind of radiation is relatively high, and the harm to the human body is very great, is likely to cause genetic mutation, if human beings receive too much ionizing radiation, it is easy to induce cancer. The second type of radiation is non-ionizing radiation, the energy of this radiation is a little weaker, the harm to the body is a little less.

In fact, some of the electrical appliances used in life are electromagnetic radiation, such as television sets, computers, microwave ovens, cell phones, power stations, subways, high-speed railways, power transmission and transformation equipment, as well as communication stations and so on. Although some electrical appliances have very low radiation, but if you suffer from this radiation for a long time, the impact on the body is also very large, especially in contact with large-scale transmitting stations and processing equipment.

In addition to nuclear radiation in nature, marble, animal bones, soil, etc. will produce natural radiation, and medical radiation will also have a great impact, such as chest X-ray, X-ray and filming and other checks in the hospital, are produced by radiation. So people actually suffer from sources of radiation all the time in their lives, and humans themselves are sources of radiation. But there are good and bad sources of radiation, and the strength of the radiation has a lot to do with it.

The most serious radiation is nuclear radiation, once suffered nuclear devastation of the region, basically can not be someone to live, because the human body will have a great deal of damage, is likely to lead to genetic mutations, the incidence of cancer will be higher, so as long as there is a nuclear radiation is to evacuate the place.
