A study on natural radioactivity in virgin and agricultural soil samples collected from Sungai Petani was conducted using high-purity germanium. The mean activity concentrations of 226Ra, 232Th, and 40K in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 Bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 Bq kg−1, respectively. The co...

The change of natural ionizing radiation and the radon exhalation rates from typical building materials in underground parking lots are presented article. activity concentration radionuclides 232Th, 226Ra, 40K six important types construction materials, which mostly used Lithuania, were analyzed using high-resolution gamma spectroscopy. highest values found concrete ferroconcrete samples: 226Ra...

Human activities such as waste disposal tend to impact negatively on the environment. Some products are associated with elevated levels of natural radioactivity. It was therefore, aim study investigate health risk radioactivity from Okakarara municipal dumpsite. In this study, gamma spectrometric analysis used determine activity concentrations 226Ra, 232Th and 40K in 18 soil samples. From these...
