Title: Measurement of radon concentration in some water samples belonging to some adjoining areas of Pathankot, Punjab

Abstract

The study of radon concentration was measured in some areas of Pathankot district, Punjab, India, from the health hazard point of view due to radon. The exposure to radon through drinking water is largely by inhalation and ingestion. RAD 7, an electronic solid state silicon detector (Durridgeco., USA) was used to measure the radon concentration in drinking water samples of the study area. The recorded values of radon concentration in these water samples are below the recommended limit by UNSCEAR and European commission. The recommended limit of radon concentration in water samples is 4 to 40 Bq/l given by UNSCEAR [1] and European commission has recommended the safe limit for radon concentration in water sample is 100 Bq/l [2].

  • Radon and its progeny are major contributors in the radiation dose received by general population of the world. Because radon is a noble gas, a large portion of it is free to migrate away from radium. The primary sources of radon in the houses are soils and rocks source emanations, emanation from building materials, and entry of radon into a structure from outdoor air. Keeping this in mind the study of radon exhalation rate from some soil samples of the Kharar, Punjab has been carried out using Can Technique. The equilibrium radon concentration in various soil samples of Kharar areamore » of district Mohali varied from 12.7 Bqm{sup −3} to 82.9 Bqm{sup −3} with an average of 37.5 ± 27.0 Bqm{sup −3}. The radon mass exhalation rates from the soil samples varied from 0.45 to 2.9 mBq/kg/h with an average of 1.4 ± 0.9 mBq/kg/h and radon surface exhalation rates varied from 10.4 to 67.2 mBq/m{sup 2}/h with an average of 30.6 ± 21.8 mBq/m{sup 2}/h. The radon mass and surface exhalation rates of the soil samples of Kharar, Punjab were lower than that of the world wide average.« less
  • Tests were performed by filtering a known amount of air and measuring the activity of the aerosols retained; being a gas, the radon passes through the filter, but the solid daughters RaA, RaB, and RaC' are held back on the filter, together with the dust particles. The radon concentration is calculated on the basis of the assumption that the system is in radioactive equilibrium, which is correct under free atmospheric conditions. After taking daily samples at 10 a.m. for 13 months it was established that the radon concentration varies widely between the extremes of 1 and 915 x 10/sup -18/more » curies/cm/sup 3/, with an average value of all the daily samples of 110.6 x 10/sup -18/ curies/cm/sup 3/.
