What is earthly radiation?

earthly radiation is an electromagnetic energy that comes from the ground or its atmosphere. It creates a background radiation that is always present, even if it can fluctuate on the basis of location. This is not dangerous; Some of them occur at wavelengths that do not pose a threat to human health, while in other cases the amount present is so low that it does not pose a threat to human health. Tools that measure radiation can distinguish between different sources and can return values ​​for earthly radiation separate from other sources in favor of scientists. They are constantly subject to radioactive disintegration and divide into smaller elements. All these processes produce earthly radiation. In addition, thermal radiation is part of the energy of the emitted ground. The sun warms up rocks and soil that releases the heat trapped during the evening, and various geological and molecular activities also produce heat.

scientists who studyThe radiation must set basic radiation in the background that is always present in order to identify new sources and understand their impact. Earth radiation may depend on location and values, for many places on Earth is available to help scientists calculate the basic levels. With these levels in the hand, scientists can see how activities such as nuclear energy production affect the radiation level to determine their impact on human, plants and animals. This information may be important for determining scientific policy and the development of guarantees to avoid radiation damage.

The level of earth radiation has not always been constant. The levels fluctuated throughout the country's history in response to various factors. When the country was new, more radioactive elements were present, but it disintegrated over time and was not replaced by any external sources. Scientists can determine historical levels of ground radiation with a number of tools, including measurement of existing levels and extrapolation, given the information on radioactive behaviorelements.

some confusion can surround the concept of radiation in the background. The public combines radiation with harmful elements, although there are many different forms of radiation and not all of them represent a threat to human health. For example, when someone turns the thermostat that warms the room, this person rely on thermal radiation to increase the temperature. This radiation is not harmful if it does not reach very high temperatures that the thermostat is usually designed to prevent it.
