本研究评估了使用钝化离子注入平面硅（PIPS）二极管探测器直接测量液体中α发射放射性核素的可行性。PIPS二极管探测器的性能特点和耐用性使其能够通过将二极管探测器放置在靠近液体样品的位置来直接检测液体样品中的α粒子。研究了影响溶液中α -发射体直接检测灵敏度和准确性的因素以及α / γ发射体的干扰。使用PIPS二极管检测器对液体样品进行直接分析，可以实现适用于过程控制应用的快速和直接的检测方法。(C) 2004 Elsevier B.V.版权所有
The present study evaluated the feasibility of direct measurement of alpha emitting radionuclides in liquids using passivated ion implanted planar silicon (PIPS) diode detectors. The performance characteristics and durability of PIPS diode detectors enabled direct detection of alpha particles from liquid samples by placing the diode detector in close proximity to the liquid sample. Factors affecting the sensitivity and accuracy of direct detection of alpha-emitters in solution and interferences of beta/gamma emitters have been examined. Direct assay of liquid samples using PIPS diode detectors can enable rapid and straightforward detection methodologies suitable for process control applications. (C) 2004 Elsevier B.V.
