Therefore, these two radionuclides with their different sources are useful to understand the mechanisms of aerosol removal from the atmosphere. 40K is also a natural radionuclide and has been associated with the arrival of coarse re-suspended material from the Africa continent. The bulk atmospheric deposition of 7Be , 210Pb and 40K has been measured at Málaga, south-eastern Spain from January 2005 to December 2014, on monthly basis. http://hdl.handle.net/10630/9913 Isótopos radiactivos Long - term atmospheric depositional fluxes of radionuclides at Málaga (Coastal Mediterranean Station)
