RADON IN WATER – A WATER QUALITY PROBLEM?
Unhealthy indoor climate in residential buildings has been the subject of intensive research in recent years, the purpose being to find the cause and to minimize health risks. One factor that has come under attentions radon and its decay products which when inhaled may give rise to lungcancer. Radon in drinking water can be a contributory factor to enhanced radon concentrations in indoor air. In this invesrigarion groundwater wells with enhanced radon concentrations have been localized partly with the help of already available geological information. Enhanced radon concentrations in deep groundwater wells have been discovered even outside the high radon risk areas marked on Uppsala municipality’s own radon risk map. It might be appropriate to set up a limit value for radon in drinking water and also to introduce a compulsory controll of water from deep drilled wells. “Complete abstract not presented.”
