Abstract:The indoor radon concentration level and radon effective dose rate were carried out in the health centers of Khartoum, Behri(Khartoum North), Medani and Kassala towns -Sudan, in 222 measurements, using passive integrated solid-state nuclear track devices containing allyl diglycol carbonate plastic detectors. The radon concentration in the corresponding health centers was found to vary from 60 ± 12 Bq.m -3 , in Kassala town health centers, and 34 ± 9 Bq.m -3 in Wad Medani town health centers, while Khartoum and Behri (Khartoum North) health centers are recording an average values of 49 ± 12 Bq.m -3 to 46 ± 11 Bq.m -3 , respectively. The overall average of radon concentration for health centers in our study was found to be 47 ± 11 Bq.m -3 . These values are noticed to be far below than the radon action level 200-600 Bq.m -3 as recommended by ICRP. Assuming an indoor occupancy factor of 0.8 and 0.4 for the equilibrium factor of radon indoors, we found that the annual effective dose rate from radon was estimated to be 1.19 ± 0.28 mSv.y -1 , and the relative lung cancer risk for radon exposure was found to be 1.042%. From our study, it is clear that the annual effective dose rate is lower than both the "normal" back ground level as quoted by UNSCEAR and the recommended action level of ICRP, and less than the maximum permissible dose defined by the International Atomic Energy Agency.

“…In Latin America, a study was performed with the participation of six countries, among them Mexico; of the 15 Mexican cities that were monitored, 8 exceeded in their highest levels the maximal permissible level (148 Bq/m 3 ) accepted internationally [32]. Recently an ample study was published, performed in France, which calculated the risk associated to indoors radon exposure.…”

“…Many indoor national radon surveys have been carried out in countries with cold climate such as Austria (Friedmann, 2002), Luxembourg (Roth et al, 2000), Russia (Iakovleva and Karataev, 2001) to determine the level of radon and its progeny in dwellings. Even in hot countries such as Mexico (Espinosa et al, 1999), Latin American countries (Canoba et al, 2001), Bangladesh (Srivastava et al, 2001), India (Virk and Sharma, 2000) and Hong Kong (Yu et al, 1997), indoor radon surveys have been conducted.…”
