Equivalent dose (HT) is calculated by multiplying the absorbed dose to the organ or tissue (DT) with the radiation weighting factor, wR. This factor is selected for the type and energy of the radiation incident on the body, or in the case of sources within the body, emitted by the source. The value of wR is 1 for x-rays, gamma rays and beta particles, but higher for protons, neutrons, alpha particles etc.
Where HT,R = equivalent dose to tissue T from radiation R
DT,R = absorbed dose D (in grays) to tissue T from radiation R
