DETERMINATION OF RADON ACTIVITY CONCENTRATION IN HOT SPRING AND SURFACE WATER USING GAMMA SPECTROMETRY TECHNIQUE

Naturally occurring radionuclides in water such as, 222Rn which emit gamma radiation through its decaying process could reach to human. Water samples were chosen to present ground and surface water. The groundwater samples were collected from, Perak, Selangor, Kelantan and Sembilan. The surface water samples were collected from Perak, Kelantan, and Pahang. In this study, the surface doses rate measurements were done in-situ using LUDLUM rate meter, and the radioactivity concentration levels were done by counting the water samples using gamma spectrometer with HPGe detector. The activities are ranged from (0.29-1.41 Bq/l)
