Determination of 238U and 40K Radionuclide Concentrations in Some Granite Rocks by Gamma Spectroscopy and Energy Dispersive X-ray Analysis

Autor: Hanan Al-Ghamdi, M. A. El-Nahal, I. H. Saleh, Mohamed Elsafi, M. I. Sayyed, Aljawhara H. Almuqrin

Publikováno v: Materials, Vol 15, Iss 15, p 5130 (2022)

Uranium-238 (238U) and potassium-40 (40K) are important naturally occurring radionuclides. Gamma spectroscopy is a direct, non-destructive method used to determine radionuclide concentrations, but it suffers from the interference of gamma lines. 40K
