Effective dose
Effective dose
The Effective dose (pronounced: /ɪˈfɛktɪv doʊs/) is a measure of the overall risk of exposure to ionizing radiation. It is used in radiation protection to estimate the potential risk of stochastic health effects that can occur due to radiation exposure.
Etymology
The term "Effective dose" is derived from the Latin word "effectus" meaning "accomplishment, performance" and the Old French "dose" meaning "a portion prescribed", literally "a giving or gift".
Definition
The Effective dose is a calculated quantity that considers the type of radiation, the sensitivity of each organ or tissue to that radiation, and the equivalent dose to each organ or tissue. It is measured in sieverts (Sv) in the International System of Units (SI).
Calculation
The Effective dose is calculated by summing the equivalent doses to all organs and tissues, each multiplied by a tissue weighting factor that represents the proportion of the stochastic risk attributable to that organ or tissue (Tissue weighting factor).
Related terms
- Equivalent dose: A dose quantity that takes into account the type of radiation and the energy it deposits in a kilogram of human tissue.
- Absorbed dose: The amount of energy deposited by ionizing radiation in a substance.
- Tissue weighting factor: A factor that represents the proportion of the stochastic risk resulting from irradiation of the organ or tissue.
- Stochastic effects: Health effects that occur randomly and for which the probability of the effect occurring, rather than its severity, is assumed to be a linear function of dose without threshold.
