Abstract

• The pure of drinking water is very important for health of our human beings. The water form stalactite can be used as drinking water. Radon gas involvement is a part of the fact that caused water pollution. Using RAD 7 nuclear radiation detector, we tried to test the stalactite water to know how much the level of radon gas involves in it. The following three caves from Kayin State have been experiment; Mahar Sadan cave, Kaw Ka Thaung cave and Eaik Sa Ta Ya cave. Review the results of the radon concentration are as follow; Mahar Sadan cave has 10.7 11 pCi/L, Kaw Ka Thaung cave has 24.9 13 pCi/L and Eaik Sa Ta Ya cave has 29.3 18 pCi/L.According to measurement, the extent of radon concentration in the cave cannot cause danger to human life that is why the stalactite water can be used.
