What is secondary radiation?

Secondary radiation refers to the type of radiation that is emitted after the initial radiation interacts with matter. In the context of radiation safety and protection, primary radiation is the radiation that is emitted directly from a source, such as an X-ray machine. When this primary radiation strikes an object, such as tissue or other materials, it can be absorbed, transmitted, or scattered. The radiation that results from this interaction, particularly the scattered radiation, is categorized as secondary radiation.

Understanding secondary radiation is crucial in radiation safety, as it can pose health risks in diagnostic imaging and radiation therapy settings. Measures are often implemented to limit exposure to secondary radiation, such as the use of shielding and protective barriers to ensure that both patients and healthcare workers are adequately protected from potential hazards. In summary, secondary radiation provides insight into how radiation behaves when it interacts with matter and highlights the importance of managing exposure effectively.
