RESUMO
A 70 mm. radiographic survey in 914 workmen exposed to china-clay dust was made in 1959 in an industrial plant in which kaolin deposits are processed for the earthenware industry in Ayyat, United Arab Republic. All were ex-agricultural workers and thus not exposed to any industrial dust hazards.
