Overview

Jáchymov is known as a spa using in balneological procedures among others the radon content ofthe subsoil. The therapeutic effects of Jáchymov radon waters are used since 1906.In the locality a high natural ionization of the atmosphere can be anticipated which hastens thesedimentation of flying dust aerosol and thus purifies the atmosphere. A stay in a permanentlypurified and ionized atmosphere has a favourable impact on the health of exposed subjects. Theauthors made assessment of the electroionic microclimate at selected places of three major spafacilities. The measurements were made at the sites of the most frequent stay of patients and staff.Part of the measurements was evaluation of the environmental concentration of light ions of bothpolarities. A high ionization of the atmosphere was found indoors as well as outdoors. The valuesinside the premises reach concentrations of n.10 3 for light ions of both polarities. Although they arerecommended as the long-term optimum for humans, they are only exceptional in the Czech Republicdue to the contamination of the atmosphere.Evaluation of the patients health status confirmed the favourable effect of the highly ionizedatmosphere.
