SBIR Phase I: Development of a Radiochemical Sensor for Environmental Applications

这个小型企业创新研究一期项目提出了一种新型的放射化学传感器，该传感器结合了萃取色谱和水流式细胞辐射传感器。该传感器将允许对地表水、地下水和饮用水中的一种或一组放射性同位素进行量化，其α -和（或）β -发射放射性核素的水平要低得多。与传统的在线传感器相比，这种灵敏度的提高将大大增强科学家和工程师用于环境监测的工具。传统的放射化学技术既耗时又昂贵。与现有技术相比，该传感器以更低的成本和更高的灵敏度提供了接近实时的放射性污染定量的可能性。监测来自医院、研究机构和/或生产设施的放射性废水只是一个潜在的应用。＊＊＊

*** 9760934 Harvey This Small Business Innovation Research Phase I project proposes a novel radiochemical sensor that combines extraction chromatography with an aqueous flow-cell radiation sensor. The sensor will allow for quantification of a radioactive isotope or group of radioactive isotopes in surface water, groundwater and drinking water at much lower levels for alpha- and/or beta-emitting radionuclides. This increased sensitivity over conventional on-line sensors will greatly enhance the tools used by scientists and engineers for environmental monitoring Monitoring of radioactivity is important in environmental science applications. Traditional radiochemical techniques are time consuming and expensive. The sensor offers the possibility of near real-time quantification of radioactive contamination at a lower cost and higher sensitivity than currently available techniques. Monitoring of radioactive effluent from hospitals, research institutes and/or production facilities is just one potential application. ***
