Distribution Of Natural Radionuclides For Sedimentry Rock Samples From Southwestern Sinai And Their Environmental Impacts, Egypt

Some sedimentary rock samples were collected from Um-Bogma area, Sinai for investigating by γray spectrometry. The main goal of the current study was estimation the specific activities of natural radionuclides; analyze the data by statistical calculations to get the correlation ratios between radioelements and their ratios, to give information about enrichment and depletion as a result of alteration processes. The exposure risk was determined through dose, equivalent radium and annual effective dose calculations. This study reveals in general that all samples are exceeding the world permissible safe criteria and consider a risk source for human environment. Fractionation is noticed in one sample which showed migration out of uranium
