Development of new sensitive instrumentation for radon detection

越来越需要了解和控制放射性氡气和相关核素，这不仅是因为它可能造成环境健康问题，而且还因为氡追踪可以在多个领域提供诊断工具，例如岩石裂隙地质学、核安全工业和生物物理学。在新的罕见事件物理实验中，相关的核反冲也可以模拟感兴趣的真实粒子信号。该博士学位是与世界领先的氡仪器工业生产商Durridge合作进行的，由于我们之前的合作，Durridge现在在谢菲尔德设有欧洲中心，旨在推动这些地区低水平氡检测的前沿。特别是发展研究氡进入不同气体环境（包括气井和矿井）时的技术。这不仅是地质学家的兴趣所在，也是一种改进辐射探测仪器的手段，这种仪器使用不同的气体作为探测介质，受到氡背景的影响。在Spooner and Durridge首席执行官Sadler的指导下，该学生将设计、建造并现场测试一种新型仪器，包括首次绘制气态矿井环境中的氡辐射图。

There is increasing need to understand and control radioactive radon gas and related nuclides both because it can pose an environmental health issue but also because radon tracking can provide a diagnostic tool in multiple fields, for instance in the geology of rock fissures, the nuclear safety industry and in biophysics. In new rare event physics experiments the associated nuclear recoils can also mimic the true particle signals of interest. This PhD, undertaken in collaboration with the world's leading industrial producer of radon instrumentation, Durridge, which now has its European centre in Sheffield thanks to our previous collaborations, aims to push the frontiers of low level radon detection in these areas. In particular, to develop techniques for study of radon when it is emanated into different gaseous environments, including gas wells and in mines. There is interest here from geologists but also as a means of improving radiation detector instruments that use different gases as the detector medium and suffer from radon backgrounds. The student, supervised by Spooner and Durridge CEO Sadler will design, build and field-test a novel new instrument, including mapping for the first time the radon emanation in a gaseous mine environment.
