Scattered radiation refers to the radiation that has been deflected or scattered from its original path. Some synonyms for this term include diffuse radiation, backscattered radiation, and secondary radiation. Each of these terms describes radiation that has been scattered in a different way. Diffuse radiation is often used to refer to radiation that has been scattered by the atmosphere, while backscattered radiation describes radiation that has been scattered back towards the source. Secondary radiation, however, is a more general term that can be used to refer to any radiation that is produced as a result of the interaction between primary radiation and matter. Regardless of the term used, scattered radiation can pose significant risks to our health and safety.
