Beryllium-7 specific activity in surface air and its correlation with meteorological variables, solar zenith angle, and number of sunspots
(RAD Association, 2016)
This analysis presents linear correlations of beryllium-7 specific activity in surface air with several variables measured in Helsinki, Finland, over 1987-2011. Measurements of beryllium-7 are linearly correlated with the ...
Winter extremes of beryllium-7 surface concentrations in northern Europe
(Proceedings of the Second International Conference on Radioecological Concentrations Processes (50 years later), November 6–9, 2016, Seville, Spain, 2016)
Specific activity of cosmogenic 7
Be in surface air generally shows a spring-summer maximum. However,
extremely high 7
Be concentrations in surface air also occur during winter. The aim of our analysis is to
characterise ...
Analysis of extreme beryllium-7 specific activities in surface air
(Niš : University, Faculty of Electronic Engineering, 2016)
The maxima in a large dataset of the beryllium-7 specific activities measured in surface air in
Helsinki, Finland, over 25 years (1987-2011), are analysed. The measurements at this station were
performed with a varying ...
