This SBIR Phase II grant supports research and development of nuclear radiation detectors fabricated from the semi- conductor material thallium iodide. Thallium iodide has an extremely high photoelectric absorption efficiency for gamma radiation and a large semiconductor bandgap. These properties render the material an exciting candidate for specialized applications where small size, high efficiency and relaxed environmental criteria rule out use of the available materials. The research will develop techniques for producing ultra high purity thallium iodide, building on promising steps in this director that were taken in the Phase I project. Radiation detectors fabricated from thallium iodide would have important advantages over existing detectors, for applications in nuclear and particle physics research and in measurements important in industrial processing control, and in nuclear medicine.//

SBIR第二期拨款支持研究和开发由半导体材料碘化铊制造的核辐射探测器。碘化铊对伽马辐射具有极高的光电吸收效率和较大的半导体带隙。这些特性使该材料成为小尺寸、高效率和宽松的环境标准排除使用现有材料的特殊应用的令人兴奋的候选者。该研究将开发生产超高纯度碘化铊的技术，以该项目第一期所采取的有希望的步骤为基础。//用碘化铊制造的辐射探测器在核物理和粒子物理研究以及在工业加工控制和核医学中重要的测量方面的应用将比现有的探测器具有重要的优势
