Abstract

Dust fallout fluxes of ²¹⁰Pb and ⁷Be were measured in Kuwait during October 2009–August 2011. The annual average depositional fluxes of ²¹⁰Pb and ⁷Be 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 ⁷Be and ²¹⁰Pb 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 ²¹⁰Pb deposition has a strong correlation with dust deposition because of its terrestrial abundance. Whereas the ⁷Be a radionuclide shows a weaker correlation with dust deposition.
