Primordial Radionuclide Concentrations and Gamma Ray Dose Rates of Black Construction Sand from Longonot Sand Mines in Naivasha, Kenya
The radiological characteristics of black construction sand from the Longonot volcanic region of Kenya were investigated using a calibrated NaI(Tl) gamma spectrometer. Activity concentrations of ²³²Th, ²³⁸U, and ⁴⁰K, together with the associated radiological screening parameters, were evaluated in 56 sand samples. The...
