What are the different types of radiation and how do they differ in terms of risk ?
This text discusses two main types of radiation: ionizing and non-ionizing, detailing their characteristics, examples, and potential risks. Ionizing radiation, which includes alpha particles, beta particles, gamma rays, X-rays, and neutrons, can damage living tissue and DNA, leading to cancer and other health issues. Non-ionizing radiation, such as ultraviolet light, visible light, microwaves, radio waves, and extremely low-frequency radiation (ELF), generally poses lower risks but can still cause harm with high levels of exposure. The text emphasizes the importance of managing exposure to both types of radiation to mitigate potential risks.
