Radon, thoron and progeny constitute the single largest source of natural radiation exposure for humans. In addition to the dose due to inhalation, these elements also contribute significantly to radiation dose due to ingestion. Keeping this in view a study has been performed to assess the radon concentration in water and associated ingestion dose to local population in Kapurthala district of Punjab, India. The Smart RnDuo portable continuous radon (222Rn) monitor was used to measure the dissolved radon concentration in drinking water samples collected from 37 different locations from Kapurthala district. The aim of the present investigation was to calculate the ingestion dose due to radon for different age group. The Radon concentration in drinking water samples are varied from a minimum value of 0.59 ± 0.22 Bql-1 to a maximum value 5.49 ± 0.67 Bql-1 with a geometric mean value of 1.99 Bql-1. The recorded values are within the prescribed safe limit recommended by WHO, USEPA and UNSCEAR. The physicochemical parameters such as TDS, salinity, EC, pH has been measured and correlated with radon concentration.
