congruent value compared to the study results . In comparison , the total effective dose rates from Pakistan , India , Turkey , and the Qassim area of Saudi Arabia showed lower values concerning our results , on the other hand , higher values were reported for the Iwaraja-Ifewara faults in southwestern Nigeria and Venezuela .
Table 1 and Figures 8 and 9 show the estimated values of the effective dose rates for the aimed age groups , namely , infants , children , and adults , have ranged from 16.28 ± 1.37 to 192.99 ± 32.03 mSv . y �1 ; 10.85 ± 0.91 to 128.66 ± 21.35 mSv . y �1 and 7.75 ± 0.65 to 91.90 ± 15.25 mSv . y �1 , with mean values of 80.60 ± 11.27 mSv . y �1 ; 53.73 ± 7.51mSv . y �1
