On-site analytical laboratory during decommissioning: Mobile lab

The scaling factor could be applied for determining the activity of hard-to-measure (HTM) radionuclides. However, this methodology can lead to overestimate the activity of HTM radionuclides in some cases. Therefore, the direct analysis of HTM radionuclides using chemical separation should be performed. It creates issues related to the shipment of radioactive samples from the site to the external analytical laboratory. It is complex, expensive and time-consuming, and can sometimes cause a delay in the dismantlement planning. Radiological measurements of decommissioning sample out of site is not good way to manage high throughput of samples in a timely manner. In this study, we conceptually designed the mobile lab for the on-site radiological characterization during decommissioning and described the analytical method and instruments which are optimized for the mobile lab
