Description

Over the last two years, a number of datasets have been made available to the UK academic community from ~100 SIGMA detectors deployed in London during 2017-2018.  These datasets contain real threats and background, however, lack ground truth makes detailed analysis of detection probability and ID challenging.  A new dataset with injected threats (known isotope, activity, speed) into regions of real background data  is described for the NaI SIGMA detectors at a top level.
