Effects of collector types in sampling of atmospheric depositional fluxes.
The bulk gross alpha, gross beta and (7)Be depositional fluxes were measured in Málaga (36.7 degrees N, 4.5 degrees W), a coastal Mediterranean station in the south of Spain for one whole year. In order to quantify the local variation of deposition rates, we have analysed the monthly results from two deposition collectors: a "pot "collector with a continuous water-covered surface and a "funnel" collector. In general, the alpha and beta depositional fluxes from the funnel collector were approximately two times lower than the pot collector. Whereas for the cosmogenic (7)Be, the depositional flux of (7)Be from funnel collector was also approximately two times lower than the pot collector. A good correlation of the depositional flux of (7)Be has been obtained from both collectors.
