The equivalent dose (EQD) received by an organ is expressed by multiplying the organ dose by a radiation weighting factor. This weighting factor accounts for the varying biological effects of different types of radiation, thereby allowing for a more accurate assessment of the potential harm to the organ receiving the dose.

When calculating EQD, it is essential to consider the specific type of radiation involved, as different types have different impacts on biological tissues. For instance, alpha particles have a higher biological effectiveness compared to beta particles or gamma rays, which is why the radiation weighting factor is used to adjust the organ dose appropriately.

This method provides a standardized way to represent the dose in terms of its biological effect, allowing for more informed decisions regarding treatment planning and risk assessment in medical dosimetry contexts.
