Effective dose (radiation)
A risk-weighted dose quantity for whole-body radiation protection.
Last updated
Effective dose is a calculated value used in the ICRP system to gauge the long-term cancer and genetic risk from low-level radiation across the whole body. It combines the radiation type and the sensitivity of each organ, summing internal and external exposures into a single number. Measured in sieverts (Sv), one Sv corresponds to a 5.5% cancer risk. It is not meant for immediate tissue damage, which is measured by absorbed dose.
