摘 要：Fifty three samples were collected from two governorates in Yemen (Taiz and Hodeida) which covered the most citizens use of these *** have been measured for gamma radiation using HpGe *** experimentally results for the activity concentrations have been used in the developed model of a Yemeni room to calculate the indoor exposure dose *** annual effective dose rate were ranged between [294.250-329.452],[1029.829] and[929.497] μSvy-1 for a habitant in a room built of concrete,granite and cement brick respectively.
