Abstract

Radon and its progeny are the major contributors in the radiation dose received by general population of the world. Keeping this in mind the environmental radon, thoron and their progeny level measurements have been carried out in some Textile Industrial Units Of Panipat, Haryana. The radon-thoron twin cup dosimeters designed by environmental assessment division of Bhabha Atomic Research Centre (BARC) Mumbai, India have been used for the study. Three pieces of LR- 115 Solid-State Nuclear Track Detectors are fixed in the dosimeters and are suspended for three months during a season. One gives radon, thoron and progeny concentration, second gives radon and thoron concentration while the third gives only the radon concentration. The different industrial units covered during present study are Bharti Udyog Panipat, P. P. International Panipat, Gupta Carpets Panipat, Shivam Textiles Panipat, Shingla Textile Panipat. To observe the effect of environmental conditions, the measurements have been carried out during different seasons of the year. The radon-thoron progeny levels and annual dose received by the inhabitants in the Industrial units under study have also been calculated. The levels are found to be higher during winter season as compared to other seasons of the year.
