DISTRIBUTION OF RADON AND URANIUM LEVELS IN GROUNDWATER OF DISTRICT PALWAL, SOUTHERN HARYANA, INDIA.

Scintillation-detector-based SMART RnDuo (AQTEK System, India) and LED fluorimeter (Quantalase Instrument, India) were used for measurements of radon and uranium concentration in 54 groundwater samples collected from different locations in the Palwal district of Haryana (India). Radon in 26% and uranium in 54% of samples were found to be at higher levels than the maximum contamination limit (11 Bq l-1) for drinking water recommended by US Environmental Protection Agency and provisional guideline level (30 μg l-1) stated by World Health Organization.
