Summary
A preliminary survey of airborne and waterborne radon concentrations was given for an area where groundwater is used as a source of public water supply. The average of the waterborne radon concentrations was 77 Bq/l for 36 samples and that of airborne radon concentrations was 18 Bq/m3for ten houses. It is concluded that the exposure dose due to radon-in-water is likely to be much smaller than the total dose from natural radiation.
