剂量当量是以组织或器官中一个点的吸收剂量乘以该点处辐射的品质因数Q,而当量剂量是以器官或组织的平均吸收剂量乘以辐射计权因子W_R。取代Q的W_R则是以入射 The dose equivalent is the absorbed dose at one point in a tissue or organ multiplied by the quality factor Q of radiation at that point and the equivalent dose is multiplied by the radiometric weight factor W_R at the average absorbed dose of the organ or tissue. The W_R instead of Q is incident
