Study of the variations of ⁷Be, ³²P, ⁹⁰Sr, ²¹⁰Pb and ²¹⁰Po in the troposphere

Abstract

Marenco and Fontan (1974) have reported on the extensive measurements carried out by them at Toulouse, France, on the radionuclides mentioned above. Using these data as well as their theoretical calculations on the variations in activity levels and activity ratios by vertical exchange, precipitation scavenging, etc., they draw conclusions regarding the sources of the different isotopes and the causes for their seasonal variations.
