Biological doses are measured in

WebToxicity can be measured by its effects on the target (organism, organ, tissue or cell). Because individuals typically have different levels of response to the same dose of a toxic substance, a population-level measure of toxicity is often used which relates the probabilities of an outcome for a given individual in a population. WebThere are a number of different measures of radiation dose, including absorbed dose ( D) measured in: gray (Gy) energy absorbed per unit of mass ( J ·kg −1) Equivalent dose ( H) …
