ABSTRACT

 

The present work reports the results of a study performed, by gamma spectral analysis, on different soil samples collected from Ramnicu Valcea, an important Romanian city. The purpose of this research is to estimate the gamma dose rate in the out-door air (at a height of 1 m above the ground), in order to compare the result thus obtained to the annual effective dose value which is recommended not to be exceeded for the population. By calculating the mean activity concentrations for the primordial decay chains (those of Radium-226 and Thorium-232), as well as the mean activity concentration for the Potassium-40 radioisotope, one may evaluate the gamma dose rate received by the public in Ramnicu Valcea, which is proved to be lower than the maximum admitted value, so the study leads to the conclusion that the inhabitants are not dangerously exposed to this kind of radiation.

 

KEYWORDS: gamma dose rate, naturally occuring soil radiation, Ramnicu Valcea
