Study of Be-7 and Pb-210 as radiotracers of African intrusions in Malaga (Spain)

摘要

The relationship between the particulate matter in the atmosphere of Malaga and the origin of air masses with special attention to African intrusions was analyzed. The concentrations of PM10 and the activities of some radionuclides (Be-7 and Pb-210) as tracers of these intrusions are discussed. The origin of these radiotracers is completely different. Pb-210 is a good tracer of air masses traveling close to the ground and come from inland areas. On the other hand, the production of Be-7 is very low in the vicinity of the Earth's surface, and increases with altitude, making it a great tracer of stratospheric air masses in the troposphere.
