Abstract

Measure of uranium in some samples of natural deposits in Morocco: environmental implications. In this work, we report the measurement results of uranium content in some natural formation samples in Morocco. The such results are used in several studies concerning the Earth sciences and the Environment such as geochronology, archaeology, geophysical and geophysical studies and prospecting of radioactive pollution. The analyses were carried out on some of natural deposits samples such as the corals, the fossil shells molluscs, the phosphates, the travertines, the lichens and of the impure carbonate deposits. Measurements were realized by spectrometry alpha for fossil shell molluscs, corals, travertines and impure carbonates, by Gamma spectrometry using a well detector with scintillation NaI for phosphates and by neutron activation for lichens. Isotopic 234U/238U ratio was also measured and discussed.
