Decommissioning of radiactively contaminated structures is expensive , time consuming and hazardous. Conventional methods used to assess the best disposal route for radioactively contaminated concrete, brick, rubble etc require the operator to take a sample from the surface generating contaminated dust and for that sample to be taken off-site to a laboratory. This project will assess and evaluate the design, fabrication and implementation of an interface for a new device, ViridiScan. This new tool will permit the simultaneous analysis of radioactively contaminated surfaces for elemental & isotopic composition, and total alpha radiation. It will provide a new, novel & robust approach for in-situ on-site characterisation which is rapid and sensitive. This has never previously been attempted.

放射性污染结构的退役是昂贵、耗时和危险的。用于评估受放射性污染的混凝土、砖块、瓦砾等的最佳处置途径的传统方法要求操作人员从产生污染灰尘的表面取样，并将该样品带到场外的实验室。该项目将评估和评价新设备ViridiScan接口的设计、制造和实施。这种新工具将允许同时分析放射性污染表面的元素和同位素组成以及总α辐射。它将为现场表征提供一种新的，新颖的和稳健的方法，该方法快速，灵敏。这是以前从未尝试过的。
