The United Kingdom (UK) has a significant legacy of nuclear installations to be decommissioned over the next 100 years and a thorough characterisation is required prior to the development of a detailed decommissioning plan. Alpha radiation detection is notoriously time consuming and difficult to carry out due to the short range of alpha particles in air. Long-range detection of alpha particles is therefore highly desirable and this has been attempted through the detection of secondary effects from alpha radiation, most notably the air-radioluminescence caused by ionisation. This paper evaluates alpha induced air radioluminescence detectors developed to date and looks at their potential to develop a stand-off, alpha radiation detector which can be used in the nuclear decommissioning field in daylight conditions to detect alpha contaminated materials.
英国有大量核设施，未来100年内需要退役，在制定详细的退役计划之前，需要进行全面的特性描述。由于α粒子在空气中的射程较短，α辐射检测耗时且难度大。因此，非常需要对α粒子进行远距离检测，人们已尝试通过检测α辐射的次级效应来实现，最显著的是电离引起的空气辐射发光。本文评估了迄今开发的α诱导空气辐射发光探测器，并探讨了开发一种远距离α辐射探测器的潜力，该探测器可在日光条件下用于核退役领域，以检测受α污染的材料。
