Abstract:
Long-term variation of outdoor 222Rn concentration was investigated for 17 years (1992 - 2009). The results presented in this paper were obtained within the framework of the monitoring program performed in Bacau - Romania, as a component part of the National Environmental Radioactivity Survey Network (NERSN), under the Ministry of Environment and Forests.The method used was based on indirect determination of outdoor radon, from total beta measurements of atmospheric aerosols filters, using a low background total beta counter and 90(Sr/Y) reference standard.Analysis of the time series of 222Rn concentrations in the low atmosphere make evident different patterns of variation of outdoor radon concentrations: diurnal, seasonal and annual variations.
