The contents of natural radionuclides ( 226 Ra, 232 Th and 40 K) were measured in sedimentary phosphate rock samples (Abu-Tartur phosphate, Western Desert Egypt) by using gamma spectrometry (NaI (Tl) 3"3 3"). Phosphate and environmental samples were collected from Abu-Tartur phosphate mine and the surrounding region.

impact of abu tartur rock. MASTERARBEIT . The Abu Tartur mine is located in the Western Desert of Egypt, 50 km west of El Kharga City. Geologically, the Abu Tartur plateau is built by a sequence of Upper Cretaceous (Campanian – Maastrichtian) phosphorites, black shales and glauconitic sandstones. The phosphate deposits are of great economic ...
