Quantum dots could provide the basis for a method of radiation dosimetry which could be of use in a range of medical and industrial applications. Recent developments in materials science make the reliable manufacture of nanocrystals possible and allow for the variation in the size and composition of manufactured quantum dots. The purpose of this work is to optimise the design of a self-calibrating radiation dosimeter for proposed use in the security and healthcare sectors, with applications which include the determination of received radiation dose by patients and the verification of sterilisation of items such as mail and medical equipment. This will be achieved by investigating the effects of ionising radiation on quantum dots and determining the optimum concentration and size for the detection of electron and gamma irradiation. If successful, this would open the way for the production of a wide range of self-calibrating dosimeters that can be produced in different matrices, which could be read-out optically in real-time and which are amenable to printing onto packaging and other complex surfaces.

量子点可以为辐射剂量测定方法提供基础，该方法可用于一系列医疗和工业应用。材料科学的最新发展使得纳米晶体的可靠制造成为可能，并允许制造的量子点的尺寸和成分发生变化。这项工作的目的是优化自校准辐射剂量计的设计，以供安全和医疗保健领域使用，其应用包括确定患者接收的辐射剂量以及验证邮件和医疗设备等物品的灭菌情况。这将通过研究电离辐射对量子点的影响并确定检测电子和伽马辐射的最佳浓度和尺寸来实现。如果成功，这将为生产各种自校准剂量计开辟道路，这些剂量计可以以不同的基质生产，可以实时光学读出，并且可以打印到包装和其他复杂表面上。
