Taustauuringuid

Taustauuringuid, also known as "background radiation," refers to the low-level radiation that is present in the environment at all times. This radiation is a result of natural and artificial sources. Natural sources include cosmic rays from space, radioactive elements in the Earth's crust, and radon gas. Artificial sources include medical and industrial uses of radioactive materials, as well as fallout from nuclear weapons testing. Background radiation is measured in units of radiation dose, such as millirems or microsieverts, and varies depending on location and altitude. It is a constant part of the human environment and is generally considered safe at low levels. However, high levels of background radiation can pose health risks, including an increased risk of cancer. Monitoring and managing background radiation levels is an important aspect of environmental and public health.
