Radiation refers to the emission or transmission of energy in the form of waves or particles through space or through a material medium. It can be categorized into two main types: ionizing and non-ionizing radiation. Ionizing radiation has sufficient energy to ionize atoms or molecules by removing tightly bound electrons, thereby producing charged particles. Examples include alpha particles, beta particles, and gamma rays. Non-ionizing radiation, on the other hand, does not have enough energy to ionize atoms or molecules. Examples include radio waves, microwaves, and visible light.

Radiation is a natural part of the environment and is present in various forms, such as cosmic radiation from space, terrestrial radiation from the Earth's crust, and radiation from radioactive materials. It is also produced artificially through medical, industrial, and scientific applications. The effects of radiation on living organisms can be both beneficial and harmful. At low doses, radiation can be used for sterilization, medical imaging, and cancer treatment. However, high doses of radiation can cause radiation sickness, genetic mutations, and increased cancer risk.

The measurement of radiation is crucial for understanding its effects and ensuring safety. The most common units of measurement are the gray (Gy) for absorbed dose and the sievert (Sv) for equivalent dose, which takes into account the type and energy of the radiation. Radiation protection involves minimizing exposure to harmful radiation through shielding, distance, and time. Regulations and guidelines are in place to control and monitor radiation levels in various settings, including nuclear power plants, medical facilities, and industrial workplaces.
