text: Ionizing radiations are present in many aspects of life today, including both radiations occurring naturally in the environment  such as from radionuclides found in air (radon decay products), soils, food, water and the human body, as well as cosmogenesis and cosmic rays  and artificially produced radiations such as found in: medical uses of X-rays (kV tubes and MV accelerators), gamma rays from external beam/brachytherapy sources and from short-lived radionuclides used in nuclear medicine ( 99m Tc, other SPECT, PET radionuclides), as well as other emerging techniques (e.g. hadron and neutron therapies),
