AB Atmospheric deposition of radionuclides has been investigated in many studies from the aspects of bothradiation protection and geochemistry. The present study, carried out in the city of Málaga, in the southeastof Spain, focuses on the assessment of the bulk depositional fluxes of three natural radionuclides: 7Be(cosmogenic origin), and 210Pb and 40K (crustal origin). These three radionuclides are useful markers ofparticles arising from their respective sources. To obtain fundamental information of atmospherictransportation, sedimentation and geological process of particulate matter, a long-term monitoring ofatmospheric deposition has been carried out in Málaga from January 2005-December 2016. Samples ofbulk deposition were collected on a monthly basis on a stainless steel tray from January 2005 toDecember 2016. Afterwards, a volume of 6 L of the bulk deposition was reduced via evaporation to 1 Lapproximately and transferred to a Marinelli geometry container for gamma counting. Additionally,aerosols samples were collected weekly in cellulose membrane filters of 0.8μm pore size and 47mmdiameter with an air sampler lodged in an all-weather sampling station, situated on the roof near the bulkrain collector. Gamma counting of the aerosols and bulk deposition samples was performed using anintrinsic germanium coaxial detector, Re-Ge-type (CANBERRA). This study describes the results andthen discusses characteristics of atmospheric deposition of mentioned radionuclides with respect toseasonal variations and dependency on controlling factors. The depositional fluxes of all radionuclidesshowed a clear seasonal trend with summer minimum and high values in wintertime.
