In this paper, phosphogypsum (PG) with the content of 226 Ra of about 500 Bq kg-1 was
used as a clay additive in mass ratios of (0− 40)% and its influence on the radiological and …

The activity concentrations of 226 Ra, 232 Th, and 40 K from 102 building materials samples
were determined using a high-purity germanium (HPGe) detector. The activity …

Natural radioactivity in coastaline area soil of Ado-Odo/Ota has been carried out to ascertain
the presence of radionuclides using gamma-ray spectroscopy (HPGe detector). The result …

The concentrations of the radionuclides in the subsurface formation (soils and rocks) solely
depend on their geological origin, which enables its variation from point to point on the …

The extent of contamination and health risks of radionuclides in media around mining sites
in Nigeria were carried out in this study. A total of 210 soils, sediments, tailings and rocks …

The concentrations of 238U, 226Ra, 232Th and 40K maintained in phosphate rock (PR),
phosphoric acid (PA) and phosphogypsum (PG) samples and its possible radiation hazards …

In this study, copper ferrocyanide (CuFC) powder was first prepared by co-precipitation
method, and the removal rate, sorption capacity and mechanism of sorption cesium on …

The activity concentration of 226 Ra, 232 Th and 40 K was measured in commonly building
materials used in Nigeria from commercial supplier using High Purity Germanium Gamma …

This study measured the natural radioactivity of 226Ra, 232Th and 40K in 20 granite
samples obtained from the Erongo Mountain Belt and Usakos Dome of the Erongo region …

This study reports the exhalation rates of radon and thoron from surface soil collected from
60 rural sites of district Hisar, Haryana, India. The exhalation rates of Rn222 (radon) and …
