DESCRIPTION
The radon content of air can increase at workplaces or dwellings. The Turkish Bath with radon spa merit particular attention Hungarian legislation for workplaces Radon action level 1000 Bq/m 3 yearly average radon concentration It means 6.3 mSv/year by 2000 h/year working time and 0.4 equilibrium factor Recommended standard for drinking water According to EC Recommendation (2001/928/Euratom) 1000 Bq/l as an action levelTRANSCRIPT
