Description
Civilian nuclear facilities intermittently release radioxenon isotopes of monitoring interest, and these isotopes are routinely detected at IMS noble gas stations. The current IDC noble gas categorization scheme identifies anomalous detections by comparing measured concentrations to historical values observed at a given station. Here we explore complementary anomaly detection methods and criteria that are based on evaluating if detections can plausibly be attributed to typical emissions from known civilian nuclear facilities. The method shows promise for screening anomalies that may lie within historically normal concentration values as well as providing additional context to detections that lie above historical thresholds.
