Abstract

A high-resolution HPGe (High Purity Germanium) detector, integrated with a low background γ-ray counting system, was used to perform a radioactive analysis of marl clay, Nile silt and pottery samples from handcrafted pottery production sites in Hijaza, Qena, Upper Egypt. The analysis focused on the activity concentrations of natural radionuclides namely 238U, 232Th and 40K which are key contributors to environmental radioactivity. The average activity concentrations measured for 238U, 232Th and 40K were found to be 13.72 ± 0.77 Bq/kg, 8.97 ± 0.39 Bq/kg and 94.91 ± 4.73 Bq/kg, respectively.
Based on these activity concentrations, several radiation hazard indices were calculated, including radium equivalent activities, absorbed dose rates (Dout), the Gamma radiation representative level index (Iᵧ), Furthermore, the study estimated annual effective dose equivalent (Deff), external and internal hazard indices (Hext & Hint), excess lifetime cancer risk (ELCR) and the annual gonadal equivalent dose (AGED). These values were compared with globally recommended standards to assess the potential radiation hazard posed by the samples.
