The health hazards of the radioactive gas radon on general public are well known. In order to understand the level and distribution of radon concentrations in soil-gas of Rajasthan, a radon survey was carried out at different locations using RAD7, an electronic radon detector. The measurement of radon concentration in soil-gas was carried out at four different depths (10, 40, 70, and 100 cm). The minimum value of radon concentration is observed at 10 cm depth and maximum at 100 cm depth. As expected, our data show an increase of soil-gas radon concentration levels with depth. The present results are compared with the available radon data from other studies.
