Sažetak
Traditionally, people like bathing in spas. Water in spas has been used as a basic therapeutic agent for different balneological treatments in the form of a bath or inhalation. Water as an essential nutritient, consists of numerous elements which are desirable for human survival. Thermal water applied at spas comes from underground sources of mineral waters that are rather high in radium concentration. Radon for therapy comes from underground sources of mineral radioactive water, or is used for treatments in the form of collective inhalations inside the caves. In the air of the treatment rooms radon occurs together with its radioactive decay products. In our studies the concentration of radon progeny (working levels) have been determined at some thermal health resources in Republic of Croatia (Bizovačke, Istarske, Krapinske, Stubičke, Tuheljske and Varaždinske spa). The potential alpha energy concentration of radon-decay products was estimated on the basis of the alpha activity measurements of radioactive aerosols collected on filters during the process of air sampling. Results of the determination of potential energy concentrations and those of exposure value were expressed in working level (WL) and working level month (WLM) units, respectively. The legislation presently valid in the Republic of Croatia is based on the IAEA recommendation. It is concluded that the doses resulting from the short-term and temporary exposures to radon progeny from waters used in spas are not subject to the dose limits.
