Dust fallout fluxes of 210 Pb and 7 Be were measured in Kuwait during October 2009-August 2011. The annual average depositional fluxes of 210 Pb and 7 Be were 134 and 422 Bq m -2 , respectively. The temporal variations of both radionuclides showed a maximum deposition during April of 2010 and 2011.A strong linear relationship between 7 Be and 210 Pb was found. The average dust depositional rate was about 50 mg m -2 h -1 with a maximum of 460 mg m -2 h -1 , while the extreme value of 664 mg m -2 h -1 was recorded in March 2011 when a massive dust storm hit Kuwait. The 210 Pb deposition has a strong correlation with dust deposition because of its terrestrial abundance. Whereas the 7 Be a radionuclide shows a weaker correlation with dust deposition.
