[en] Environmental gamma radiation levels in Lahore city were measured using the radiation monitor which employs G. M tube. Average absorbed dose rate in air varied from 140 nGy h/sup -1/ to 282 nGy h/sup -1/ with the mean value of 197 nGy h/sup -1/. The effective dose rate levels in Lahore city were found in the range of 860 plus minus 147 micro Sv y/sup -1/ to 1732 plus minus 187 micro Sv y/sup -1/ with the mean value of 1208 plus minus 244 micro Sv y/sup -1/, whereas annual average effective dose equivalent due to terrestrial component only is 275 micro Sv. The collective effective dose equivalent to the population in the city is 1432 man.Sv. y/sup -1/. These radiological doses are not posing any significant health hazards. (author)
