| Abstract | ||
| This study has been done by solid state nuclear track detectors used for measuring Radon concentration levels and the annual effective dose carried out in (18) houses in some regions in ( Sahel- Nenawa ) during winter season 2011 . Long term measurement of indoor radon concentration have been taken , using a previously calibrated passive diffusion dosimeters . The measurement of indoor radon concentration obtained in winter for living rooms ranged between 40 Bq. & 59.6 Bq. with an average value of 46.9 Bq. while in the bedrooms ranged between 50 Bq. to 72.3Bq. with an average value of 61.1Bq. . The average value for all regions is 53.5 Bq. .Also the annual effective dose ranged between 1.14mSv to 1.66mSv with an average of 1.35 mSv . The data shows that the average value of Radon concentration in bedrooms higher than of living rooms | ||
