Title: Indoor radon levels and natural radioactivity in Turda salt mine

Abstract: The purpose of the study is to evaluate the activity concentrations and distribution of natural radionuclides in Turda salt mine having in view the development on the future of the speleotherapy in this salt mine. The radon, gamma ray and gross alpha and beta radiation measurements have demonstrated the presence of low concentrations of natural radionuclides in rock salt and soil samples collected from different points of the salt mine and sustains the development of speleotherapy in this mine.

Keywords: gamma ray, alpha radiation, beta radiation, salt mine, speleotherapy
