Wet depositional fluxes of 210Pb- and 7Be-bearing aerosols at two different altitude cities of North Pakistan

► 210Pb and 7Be fluxes in open rain were higher than that of throughfall samples. ► Seasonal dependence of radionuclides has been observed. ► 210Pb and 7Be can not be used as independent atmospheric tracers. ► 210Pb fluxes at Islamabad are higher than at Murree.
