*** 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. ***

* 9760934哈维 这个小企业创新研究第一阶段项目提出了一种新型的放射化学传感器，它将萃取色谱法与水性流动池辐射传感器相结合。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定量，其α和/或β发射放射性核素的水平要低得多。 这种比传统的在线传感器更高的灵敏度将大大增强科学家和工程师用于环境监测的工具 放射性监测在环境科学应用中很重要。 传统的放射化学技术既费时又昂贵。该传感器提供了以比目前可用技术更低的成本和更高的灵敏度对放射性污染进行近实时量化的可能性。监测医院、研究机构和/或生产设施的放射性流出物只是一个潜在的应用。 ***
