Sädeannos
Sädeannos, often translated as radiation dose, is a fundamental concept in radiometry and radiation protection. It quantifies the amount of ionizing radiation absorbed by a material, typically biological tissue. The primary unit for absorbed dose is the Gray (Gy), defined as one joule of energy absorbed per kilogram of mass. Historically, the rad was used, with 1 Gy equaling 100 rad.
While absorbed dose measures the energy deposited, it does not fully account for the biological impact of
Effective dose is a further refinement that accounts for the varying sensitivity of different organs and tissues
