Hand-held radiation sensors are of high value to a wide range of industry and areas such as homeland security. Key requirements for such sensors are high energy resolution and good bulk efficiency. Conventionally, it is difficult to achieve both with the same device. Semiconductor detectors like CZT have high resolution but small volume, hence, low efficiency, while scintillator detectors have high efficiency but much poorer energy resolution. We have developed a scintillator-based hand-held radiation sensor product with Kromek, a UK-based company, as part of a short KTP project. This project aims to substantially improve the performance of this product by exploring next-generation scintillator materials and novel photosensors. This will allow Kromek to stay ahead of the market and develop new products.

手持式辐射传感器对广泛的行业和领域（如国土安全）具有很高的价值。这种传感器的关键要求是高能量分辨率和良好的体积效率。传统上，很难用相同的设备实现这两个。像CZT这样的半导体探测器具有高分辨率但体积小，因此效率低，而闪烁体探测器具有高效率但能量分辨率差得多。作为KTP短期项目的一部分，我们与英国公司Kromek合作开发了一款基于微波炉的手持式辐射传感器产品。该项目旨在通过探索下一代闪烁体材料和新型光电传感器来大幅提高该产品的性能。这将使Kromek保持市场领先地位并开发新产品。
