INGESTION AND INHALATION DOSES DUE TO INTAKE OF RADON IN DRINKING WATER SAMPLES OF AMRITSAR PROVINCE, PUNJAB, INDIA

Abstract

Abstract In the present investigation, the ingestion and inhalation dosage for the particular body organs in light of the intake of radon through ground water utilised by the occupants have been assessed in the different villages of the Upper Bari Doab region of Amritsar province, India using an electrostatic collection type radon monitor (RAD7) analyzer with RAD-H2O accessory. The mean radon activity level in water was seen to be 8.34 ± 2.99 Bql−1. The newborn children have higher radiation dosage than the other age groups because of their high dosage transformation factors. However, the radiation dosage received by all different age groups significantly less than the UNSCEAR and WHO suggested a level of 100 μSv y−1. The annual effective dosage for the diverse body organs because of the intake of radon was moreover ascertained and found the maximum dosage for lungs than other organs. The radiation dosage received by bronchial epithelium by the means of inhalation was likewise high when contrasted with that by stomach walls through ingestion.
