The activity concentrations of 40 K, 226 Ra, and 232 Th in the soil samples collected from Owo Local Government of Ondo state, Nigeria, were assessed by gamma spectrometric techniques using a Na(TI) scintillation detector, encapsulated in a 5 × 5-cm-thick lead shield to reduce environmental background radiation. Results show that the ranges (and the corresponding average) of the measured activity concentrations of 40

“…However, they concluded that the usage and mining of sedimentary rocks in Turkey posed no radioactive harm to people as the ADR of the NORMs in the rocks is less than the acceptable global limit. Measurement of the exhalation rate of radon was done by Kaliprasad et al (2017). It was discovered that the ADR for radon in the study area was less than the global recommended limit.…”

Identifying the natural radionuclides in frequently consumed foodstuffs has attracted research interests from many researchers. In this study, we reported the quantities of natural radionuclides in frequently consumed foods in the community of Ode-Irele in Ondo State, Nigeria. Data obtained for this study were analysed using the gamma-ray spectrometer. Careful examination of six (6) different foodstuffs obtained at random for four (4) different times from the community’s local market was done: all of them were discovered to be rich in Th-232, U-238 and K-40. The activity concentrations of the foodstuffs ranged from 58.21±5.93 Bqkg-1 to 1.91±0.41 Bqkg-1 with a mean value of 11.74±1.22 Bqkg-1 for Th-232, 41.82±9.48 Bqkg-1 to 3.12±0.39 Bqkg-1 with a mean value of 12.38±2.27 Bqkg-1 for U-238 and 1854.12±126.83 Bqkg-1 to 134.72±12.62 Bqkg-1 with mean value of 280.22±30.08 Bqkg-1 for K-40. The minimum and maximum dose rates discovered from the foodstuffs are respectively 8.03nGyh-1 and 132.35nGyh-1. The mean value of all absorbed dose rates (28.99nGyh-1) was found to be less than the world average limit of 55.0nGyh-1. Comparison of the annual committed effective doses determined from the mean of the natural radionuclides (0.155mSvy-1) in the foodstuffs to the global recommended limit (1mSvy-1), showed that the frequently consumed foods by the people in the community posed no important radiation-related risk to them.

The study aims to investigate the effects of Burdur (Turkey) marble on human health by interpreting their radioactivity concentration (226Ra, 232Th, and 40K), radiological hazard parameters, chemical concentration, physical properties, and all data related to these features by using multivariate statistical methods. Chemical and radionuclide analyses were performed on marble samples. The data were interpreted by statistical analysis. According to the regression model, an increase in the concentration of vanadium carried to the environment by hydrothermal waters causes a 4.452-fold higher concentration of 226Ra. The R2 value of the model was 0.64 and it was statistically significant. The maximum concentration of 226Ra in Isparta Davraz Beige sample (M7) exceeded the values of some countries’ standards. Except for M7, the analyzed sorts of marble can be used safely in dwellings and public buildings.
