Slovenian approach in managing exposure to radon at workplaces

Radon was surveyed in all the kindergartens and schools, major hospitals, water plants, wineries, spas, in a number of other public buildings, and karst caves with emphasis on the Postojna Cave (Slovenia). In addition to radon, also the concentration of radon short-lived decay products, equilibrium factor between radon and decay products, and unattached fraction of decay products have been monitored. Effective doses were calculated and used as a criterion to require remediation.
