摘要：

In the present investigation, analysis of radon concentration in 20 water and soil samples collected from different locations of Bikaner and Jhunjhunu districts of Rajasthan, India has been carried out by using RAD7 an electronic Radon detector. The measured radon concentration in water samples lies in the range from 0.50 to 22 Bq l(-1) with the mean value of 4.42 Bq l(-1), which lies within the safe limit from 4 to 40 Bq l(-1) recommended by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR, 2008). The total annual effective dose estimated due to radon concentration in water ranges from 1.37 to 60.06 mu SV y(-1) with the mean value of 12.08 mu SV y(-1), which is lower than the safe limit 0.1 mSv y(-1) as set by World Health Organization (WHO, 2004) and European Council (EU, 1998). Radon measurement in soil samples varies from 941 to 10,050 Bq m(-3) with the mean value of 4561 Bq m(-3), which lies within the range reported by other investigators. It was observed that the soil and water of Bikaner and Jhunjhunu districts are suitable for drinking and construction purpose without posing any health hazard.
