A35 Effective dose E Sv

Consequences of radiation on the human body depend on the particular organ or tissue hit by radiation, as different organs have different responses to radiation exposure. This is the reason why another weighting factor (wT) must be introduced (see Figure A.3 [ICRP, 1990].

The sum of the equivalent dose, D, with the tissue weighting factor gives the effective dose, E [ICRP, 1990]. The dimensions of the effective dose are the same as absorbed dose and equivalent dose, joules per kilogram. Its SI unit is the same as that of the equivalent dose: sievert.
