Short-term variations in Be-7 wet deposition in the eastern part of the Czech Republic

Abstract

Weighted multiple regression analysis was used to study the relationship between 7Be wet deposition and selected characteristics of rainfall events and concentrations of pollutants and 7Be in air for the first time. We sampled 24 individual rain events (September 2013–March 2014) and simultaneously collected relevant meteorological data. 7Be content in the collected water was determined by gamma spectrometry. A dominant negative correlation was observed between 7Be volume activity and rainfall amount. The influence of PM10 and PM2.5 concentrations and weekly values of 7Be volume activity in aerosols on 7Be volume activity in rainwater was found to be statistically insignificant.
