In this article, the concentrations of radon gas (222Rn) in some houses were measured at 10 sites in Al-Najaf city, using RAD-7 radon monitoring system. The effective doses for all samples were estimated using Monte Carlo method. The Visual Monte Carlo code was used to simulate the transport of the radiation as emitted from the 222Rn through the human voxel model. Room geometry of 3×3×4 m3 was designed to estimate the people radiation dose due to the exposure to the indoor radon. The latter doses were estimated for each of male and female people individually. It is found that the radon concentrations varied from (8.75 ± 1.1 Bq/m3) to (32.32 ± 4.0 Bq/m3) with an average (20.57 ± 2.90 Bq/m3). The resulted data of the Monte Carlo calculations for male reveal that the effective dose was ranged from 2.91E-05 to 1.07E-04 μSv/h while the female effective dose was noticed to range from 2.87875E-05 to 1.06333 E-04 μSv/h.
