Here D β is the beta dose in rad, C is the concentration of the nuclide in the tissue in microcuries per gram, E β is the mean energy emitted…

(1) (2)where:Ã is the integral activity of each source; S are Snyder factors from each source to target; A0 is the injected activity; τ (MIRD) is the residence time; ND…

where (1−νx e 1−(νx/c)) = 0 for x > c/ν, D(x) is the dose rate at distance x from the source, ν is the absorption coefficient, k is a normalisation constant, c is a…
