Säteilylähteille

Säteilylähteille refers to sources of radiation. These can be broadly categorized into natural and artificial sources. Natural radiation sources are present in the environment and include cosmic rays from outer space, terrestrial radiation from naturally occurring radioactive isotopes in the Earth's crust, and internal radiation from radioactive elements within the human body. Artificial radiation sources are man-made and are used in various applications, including medical imaging and treatment (X-rays, CT scans, radiotherapy), industrial processes (gauging, sterilization), and nuclear power generation. The type and intensity of radiation emitted by a source determine its potential impact on living organisms and the environment. Understanding radiation sources is crucial for radiation protection measures, ensuring that exposure levels are kept as low as reasonably achievable. Various regulations and guidelines are in place to manage the risks associated with both natural and artificial radiation sources.
