项目摘要

Facilities associated with nuclear activities, such as reactors, radioactive substances, wastes and processing systems can often be characterised by the radiation that they emit as a result of the processes going on with them, or residual contamination. This characterisation is very important because it is often impossible to enter such facilities due to the risk to health and, conversely, without characterising them we often do not know the extent of the risk either. Fortunately, because two of the most common forms of radiation - neutrons and gamma rays - are very penetrating, it is usually possible to carry out the necessary measurements without needing to intrude on the facilities under assessment. Indeed, a great deal can be learnt from non-intrusive, non-destructive assessments of these radiation fields.Until recently, the accepted techniques for assessing gamma-ray and neutron environments were still based on technologies developed at the dawn of the nuclear industry, in the 1950s, 1960s and 1970s. Whilst adequate, these techniques were wholly analogue and as a result only a small proportion of the feasible assessments developed in the laboratory could be transported to industrial environments because extensive setting-up and configuration is needed, and they are not directly compatible with computer systems. Over the last 10 years, work at Lancaster and Liverpool Universities has focussed on digitizing these techniques, which is not easy because the speed with which the radiations interact with detecting systems is extremely fast, and often too fast for current electronic processing systems. The success of this research has enabled environments to be characterized in real-time and without the need for extensive set-up procedures that was the case for analogue apparatus, and in particular has resulted in a number new ways to image nuclear environments in terms of the radiation they emit. Of particular interest to this proposal is that it has become feasible to multiplex a much wider range of detector systems than was previously the case, with many new assay techniques being postulated if these larger, more sophisticated detector systems can be constructed for industrial applications.Because such detector systems are expensive, there are few if any of a suitable type available in the world despite the potential they hold for analysis in power production, decommissioning, cancer therapy and metrology. In this proposal we intend to construct several of these systems - a gamma-ray spectroscopy system, a neutron imaging system and a gamma-ray imaging system - to establish a cutting-edge group of facilities that can be used by researchers in the UK with an interest in these techniques. This will allow the benefits of digital radiation assay to be brought to bear on a wide range of applications without the need for every researcher to try to fund the expensive equipment necessary, and will be an efficient basis on which to continue Britain's lead in this important area.

与核活动相关的设施，例如反应堆，放射性物质，废物和加工系统，通常可以以辐射为特征，这些辐射是由于它们进行的过程而发出的，或者是残留的污染。这种表征非常重要，因为由于健康的风险，通常不可能进入此类设施，而且相反，在不表征它们的情况下，我们通常也不知道风险的程度。幸运的是，由于辐射的两种最常见的形式 - 中子和伽玛射线非常穿透，因此通常可以进行必要的测量，而无需侵入评估的设施。的确，可以从对这些辐射场的非侵袭性，无损的评估中学习很多东西。直到最近，评估伽马射线和中子环境的公认技术仍然基于1950年代，1960年代和1970年代在核工业黎明时期开发的技术。尽管有足够的时间，但这些技术是完全模拟的，因此，在实验室中开发的可行评估中只有一小部分可以将其运送到工业环境，因为需要广泛的设置和配置，并且它们与计算机系统不直接兼容。在过去的十年中，兰开斯特和利物浦大学的工作一直集中在数字化这些技术上，这并不容易，因为辐射与检测系统相互作用的速度非常快，并且对于当前的电子处理系统而言通常太快了。这项研究的成功使环境能够实时表征，而无需进行模拟设备的广泛设置程序，尤其是从它们发出的辐射方面为核环境形象化的一种新方法。该提案特别感兴趣的是，多样化的探测器系统比以前的情况更广泛，如果这些更大的，更复杂的探测器系统可以用于工业应用，则可以假定许多新的测定技术，因为这种探测器系统很昂贵，但如果在世界上有任何适合的类型，即使在世界上可以进行适当的疾病，则在癌症中具有较高的范围，而在癌症中却具有癌症，并且在癌症中进行癌症，并且在癌症中进行了癌症，并且在癌症中进行了癌症。在此提案中，我们打算构建其中几个系统 - 伽马射线光谱系统，中子成像系统和伽马射线成像系统 - 建立一个尖端的设施组，英国可以使用对这些技术感兴趣的研究人员使用。这将使数字辐射测定法的好处在广泛的应用中持续下去，而无需每个研究人员试图为必要的昂贵设备提供资金，并且将是一个有效的基础，以继续在这一重要领域继续英国的领先优势。
