Equivalent & Effective Dose
Convert absorbed dose in grays to equivalent dose in sieverts using radiation weighting, and to effective dose using an organ weighting factor, free online.
About this calculator
Equivalent dose H = absorbed dose D ร radiation weighting factor w_R (photons and electrons 1, protons 2, alpha particles 20, neutrons 2.5โ20 by energy). Effective dose E = ฮฃ w_T ยท H_T, where tissue weighting factors (ICRP 103) include lung 0.12, red marrow 0.12, breast 0.12, thyroid 0.04, skin 0.01. 1 Sv = 100 rem.
