Assessment of radiation hazard indices for sand samples from Ma'rib in Yemen

Background: This study aimed to investigate the radiation hazard indices from sand samples of Ma’rib Governorate in Yemen, where majority oil and gas facilities are installed. Methods Materials: Thirty five desert Yemen were collected tested their by using High Purity Germanium (HPGe) detector. Results: Based on measurement concentrations 226Ra, 232Th, 40K, radium equivalent activity (Raeq), concentration index (Iγ), external (Hex) internal (Hin) all calculated. Also, absorbed dose rate Air (ADR) annual effective (AED) Conclusions: Comparing practically attained results with internationally permissible values, it was found that most radiological parameters, including studied samples, fall within world's limits don't expose risks human beings environments.
