Description

Anthropogenic radionuclides of fission and activation products are frequently detected by most IMS stations located on the African continent with varying concentrations in the years 2011 to 2020. This study assesses the spatial and temporal variation of Cs-134 and Cs-137 in ground-level air at IMS stations located on the African continent from 2011 to 2020. Spatial and temporal base analysis will be performed to discern various patterns of these radionuclides. The study provides insight into the connection of anthropogenic radionuclide concentration levels in ground-level air with meteorological phenomena over the areas under investigations. It also discusses the results in view of the very few possible sources of anthropogenic radioactivity located in Africa, because for effective nuclear explosion monitoring it is important to understand the observed background. The African continent is rarely studied for this purpose and this presentation intends to fills that gap.

Promotional text

For effective nuclear explosion monitoring it is important to understand the observed background of CTBT-relevant radionuclides. This presentation fills a gap by investigating the observations of Cs-137 and Cs-134 on the African continent.
