The development of novel detectors for dosimetry in advanced radiotherapy modalities requires materials that have a water equivalent response to ionizing radiation such that characterization of radiation beams can be performed without the need for complex calibration procedures and correction factors. Organic semiconductors are potentially an ideal technology in fabricating devices for dosimetry due to tissue equivalence, mechanical flexibility, and relatively cheap manufacturing cost. The response of a commercial organic photodetector (OPD), coupled to a plastic scintillator, to ionizing radiation from a linear accelerator and orthovoltage x‐ray tube has been characterized to assess its potential as a dosimeter for radiotherapy. The radiation hardness of the OPD has also been investigated to demonstrate its longevity for such applications.

用于放射治疗剂量学的有机半导体二极管的表征。

在先进的放射治疗方式中，用于剂量测定的新型检测器的开发需要对电离辐射具有与水等效的水响应的材料，从而无需复杂的校准程序和校正因子即可对辐射束进行表征。由于组织等效性，机械柔韧性和相对便宜的制造成本，有机半导体可能是制造用于剂量学的装置的理想技术。商业有机光电探测器（OPD）与塑料闪烁体耦合，对线性加速器和正电压X射线管的电离辐射的响应已被表征，以评估其作为放射治疗剂量计的潜力。还对OPD的辐射硬度进行了研究，以证明其使用寿命长。
