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.

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，还因为氡跟踪可以在多个领域提供诊断工具，例如岩石裂缝地质学，核安全工业和生物物理学。在新的稀有事件物理实验中，相关的核反冲也可以模拟真正的粒子信号。这个博士学位，在与世界领先的氡仪器，Durridge，现在有其欧洲中心在谢菲尔德由于我们以前的合作，工业生产商合作进行，旨在推动低水平氡检测在这些领域的前沿。特别是发展研究氡散发到不同气体环境中的技术，包括威尔斯和矿井。地质学家对此很感兴趣，但也作为改进辐射探测器仪器的一种手段，这些仪器使用不同的气体作为探测器介质，并受到氡背景的影响。在斯普纳和杜里奇首席执行官萨德勒的监督下，这名学生将设计、建造和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散发图。
