What is the background radiation?

radiation is present, usually at low levels, almost everywhere in the environment; This widespread radiation is known as the background of radiation and is usually not harmful to life. Environmental radiation is largely natural and comes from natural environmental sources rather than people's activities. In the Earth's crust there are radioactive substances, some of which are even mixed in soil in small quantities. Radioactive gases also exist in small quantities in the air; These gases tend to come from the ground. Trace amounts of radioactive substances can even be found in the human body.

The radiation is a process by which the energy is released by one object and absorbed by the other. In many cases it is a harmless process and occurs on a large scale all the time. Ionizing radiation occurs when subatomical particles are released from the object sufficiently energetic to remove electrons from the atoms contained in another object; It can be harmful. Ionizing radiation of PochIt is from things such as nuclear weapons and nuclear power plants.

There are many sources of radiation in the background on Earth and on Earth, most of which are consumed by Earth's organisms, including humans, with a small harmful effect. Background radiation can also come from space in the form of space rays. Many of the cosmic rays that penetrate the atmosphere come from the Sun, although there are many distant sources that also send space rays. Such rays are usually not harmful, but widespread exposure could lead to problems with skin problems.

The majority of radiation in the background found in the atmosphere exists because the radon gas that is radioactive enters the atmosphere from its source in the Earth's crust. It then connects to different air particles that can be harmful in large quantities. For example, Uranus miners were known to gain lung cancer due to radon exposure. Radon with tAké says that it has certain medical and therapeutic uses, although they are controversial due to the risks associated with the exposure to a significant amount of gas.

While most background radiation comes from natural environmental sources, a small percentage of radiation in the environment can be attributed to human activities in science and industry. Small sources, such as radioluminescent colors, contribute to a small -scale radiation to a small extent. However, the use and testing of nuclear weapons has led to an increase in the global background radiation level. Nuclear power plants, as well as nuclear fuel recycling, also contribute to environmental radiation. Even radioactive medical devices, such as X -rays, contribute to a small -scale radiation level to a small extent.
