In radiation protection, what does the term 'absorption' refer to?

The term 'absorption' in radiation protection specifically refers to the transfer of energy from radiation to tissue. When ionizing radiation passes through matter, such as human tissue, it can deposit energy into those tissues. This process can result in various biological effects, which is why understanding absorption is crucial in radiation protection. The amount of energy absorbed is related to several factors, including the type of radiation, the energy of the radiation, and the properties of the tissue it encounters.

In radiological contexts, absorption is typically quantified by the dose received by the tissue, which informs safety standards and guidelines to minimize harmful effects on health. Monitoring and managing this transfer of energy is critical for ensuring the safety of individuals who may be exposed to radiation in medical, industrial, or research settings.
