Radiation therapy makes use of ionizing radiation to destroy malignant cancerous tissues. The success of a radiation treatment depends in part on the degree of accuracy to which the prescribed radiation dose (energy deposited per unit mass) can be delivered to the tumour. The first step involved in determining the dose to the tumour, is the measurement of the output of the irradiating device, which is, for many types of treatments a linear accelerator but is sometimes also a radioactive source.

放射治疗利用电离辐射破坏恶性癌组织。放射治疗的成功部分取决于处方放射剂量（每单位质量沉积的能量）可以递送到肿瘤的准确度。确定肿瘤剂量的第一步是测量辐射装置的输出，对于许多类型的治疗，辐射装置是线性加速器，但有时也是放射源。
