In June 2020, observations of anthropogenic radionuclides in Estonia, Finland, and Sweden that were not related to any acknowledged environmental release led a comprehensive investigation on the source cause unusual emissions. Several observed list Comprehensive Nuclear-Test-Ban Treaty (CTBT) relevant as an indicator potential nuclear test, warranted detailed investigation. While analysis aerosol samples coupled with Atmospheric Transport Dispersion Modelling (ATDM) is standard approach for particulate releases, several new techniques employed better characterize allowed useful inferences be made. These crucial forming ultimate hypothesis determining facility type location release.
