Radiation Hazards Question & Answers May 13, 2023 By Wat Electrical This article lists 50 Radiation Hazards MCQs for engineering students. All the Radiation Hazards Questions & Answers below include a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Radiation Hazards. Radiation hazards refer to the potential dangers posed by exposure to ionizing or non-ionizing radiation. Radiation can be found in various forms in the environment, including from natural sources like the sun and radioactive minerals, as well as from man-made sources like X-ray machines, nuclear power plants, and weapons. Radiation can be harmful to living organisms, and exposure to certain types and levels of radiation can have hazardous effects. The hazards of radiation can be broadly classified into two categories: ionizing radiation and non-ionizing radiation. Ionizing radiation is a type of radiation that has enough energy to remove electrons or electron flow from atoms and molecules, and it can damage DNA and other cellular structures. Examples of sources of ionizing radiation include nuclear power plants, X-ray machines, and radioactive materials. Non-ionizing radiation is a type of radiation that does not have enough energy to remove electrons from atoms and molecules, but it can still have hazardous effects. Examples of sources of non-ionizing radiation include ultraviolet light, radio waves, and microwaves. 1). What is ionizing radiation?
