WebRBE is the ratio of the dose of a reference radiation (usually high energy γ or x rays) and the dose of a test radiation type, to give the same level of biological effect. The value is generally higher at lower doses, and higher for mutational endpoints than for cell killing. WebThe absorbed dose is a measure of the actual energy deposited in the irradiated tissue and can be used to compare against deterministic effects, but it is not satisfactory for comparing the stochastic radiological risk. To estimate the stochastic risk, the type of radiation and the sensitivity of the irradiated tissues must be considered. cannot edit sss loan prn
