Ultra-fast, selective and pseudo-quantitative analysis of 99Tc in nuclear waste for screening purposes
Controlling radioactivity is essential in various fields, such as the decommissioning of nuclear power plants and nuclear medicine. In some cases, a full characterization of samples is not required; instead, a screening analysis that provides an overall indication of the activity present can be suff...
