Radiatiivsed

Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. It is a process by which unstable atomic nuclei lose energy by emitting radiation, such as alpha particles, beta particles, or gamma rays. Radiation can be classified as either ionizing or non-ionizing, depending on its energy level. Ionizing radiation has sufficient energy to ionize atoms or molecules, which can lead to chemical changes and potential health risks. Non-ionizing radiation, on the other hand, does not have enough energy to ionize atoms or molecules and is generally considered less harmful. Radiation is used in various applications, including medical imaging, cancer treatment, and industrial processes, but it also poses risks to human health and the environment. The measurement of radiation is typically expressed in units such as the gray (Gy) for absorbed dose and the sievert (Sv) for equivalent dose, which takes into account the type and energy of the radiation. Proper safety measures and regulations are essential to minimize the risks associated with radiation exposure.
