Determination of radon concentration in drinking water of Bam villages and evaluation of the annual effective dose

摘要

Background'. Radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. The presence of radon gas is common, wherever those faults are located there. Radon concentration of various drinking water resources of Bam villages; located near Bam fau was measured. Materials and Methods: This cross-sectional study was conducted in the spring of 2014. Samples were collected from 27 water resources (wells and canals) as well as 5 water storage tanks of Bam villages of Kerman province. The radon concentrations were determined by RAD7 device. The annual absorbed dose was also calculated according to the measured radon levels.
