Method RAD7 an electronic radon detector manufactured by Durridge Co. USA calibrated in-house was used to measure the indoor radon concentration levels in offices of the Administration block. Results Mean radon concentration from offices studied ranged from 134.72 Bqm-3 − 536.98 Bqm-3in all the offices. The mean of the annual effective dose due to 222Rn progeny (AEDR) in mSv/yr. is highest in GFL this value is 2.344 x 10 − 3 mSv/yr. and it’s lowest at the LFL with the value of 1.010 x 10 − 3 mSv/yr. The lung cancer cases mean, maximum and the 95th percentile per million people values obtained from offices and the obtained values are 85.81, 11.44, and 11.21. Conclusion The obtained values were lower than the public limit of 1mSvy-1 as recommended by ICRP, and this findings show a significant correlation between indoor radon effective doses obtained by other studies elsewhere.
