Data set for manuscript "Standoff alpha radiation measurement of surface contamination based on radioluminescence"

This is the dataset for manuscript "Standoff alpha radiation measurement of surface contamination based on radioluminescence". The widespread use of nuclear energy and technology has placed increasing demands on nuclear radiation monitoring techniques, and an effective standoff alpha radiation measurement of surface contamination method is of great importance in scenarios such as radioactive waste disposal and decommissioning of nuclear facilities, nuclear accident emergency response and nuclear security. Here, we present the results of the detection efficiency calibrating of standoff alpha radioactive point sources by means of simulation and experiment, respectively. At the same time, a numerical integration-based surface contamination measurement method is designed, and is computed and validated by means of experiments and simulations, respectively. Finally, the minimum detectable surface activity of the method is given for different measurement conditions. This dataset documents the original experimental records and data processing results for this manuscript.
