What does "radiation dose" measure?

The term "radiation dose" specifically refers to the amount of energy absorbed per unit mass of tissue, which is a crucial concept in radiation protection and health physics. This measurement helps to assess the potential biological effects of radiation on human tissues.

When radiation interacts with matter, it transfers energy, which can cause ionization and other effects in biological tissues. The dose is quantified in units such as grays (Gy), where one gray represents the absorption of one joule of radiation energy by one kilogram of tissue. Understanding radiation dose is essential for evaluating risks, establishing safety standards, and determining appropriate exposure limits in medical, occupational, and environmental contexts. Thus, this concept is central to ensuring the wellbeing of individuals exposed to radiation, whether it be in medical settings, industrial applications, or nuclear installations.
