Natural radioactivity of the greek spas in Ikaria, Kamena Vourla and Loutraki.

摘要

The natural radioactivity of the Greek radioactive spas used for balneological purposes is examined for a two-year period and the results show considerable fluctuations. These spas are located in different regions of different geological composition. A detailed analysis has been achieved by applying methods of gamma ray spectroscopy. All radioisotopes included in the examined spa waters in the form of gases (222Rn), as well as in the form of dissolved inorganic salts (226Ra, 208Tl, 40K), are detected and determined. A classification of the Greek spas according to 222Rn concentration is also presented. From the assessment of the natural radioactivity results in relation to different physical parameters of the gushing up of the springs areas the geological composition is proven to be the main influencing factor of the concetration of each one of the detected natural radioisotopes in the spa waters.
