In West- Central Sinai kaolin occurs interbedded with sandstones in east and northeast Abu Zenima area. The present work focuses on the composition and origin of kaolin resources of different stratigraphic settings in Sinai, as well as the natural radioactivity of these kaolin deposits .Naturally occurring radionuclides are measured radiometrically as well as chemically on the representative kaolin samples of the Carboniferous and Cretaceous kaolin resources in the studied areas of Wadi El Khaboba, Wadi El- Iseila, and Wadi-Abansakar UR - http://172.23.153.220/th.pdf ER -
