Investigation of the effect of hydrothermal waters on radionuclide activity concentrations in natural marble with multivariate statistical analysis

Abstract

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.
