The goal of radiation therapy is to use radiation to damage tumor cells to an extent that they are either dead (necrotic), or not viable to reproduce (sterile). To control the amount of radiation delivered to the patient, several physical or biological quantities have been suggested and are routinely in use. Although perhaps the most relevant quantity in radiotherapy would be a measure of cell death, the current accepted quantity is physical absorbed dose to water (energy deposited per unit mass of water).

放射治疗的目标是利用辐射来破坏肿瘤细胞，使其要么死亡(坏死)，要么不能繁殖(无菌)。为了控制对患者的辐射量，已经提出了几个物理量或生物量的建议，并常规使用。虽然放射治疗中最相关的量可能是细胞死亡的衡量标准，但目前被接受的量是物理吸收剂量到水(每单位质量水中沉积的能量)。
