Abstract. In this paper, the radon concentrations in the houses of (10) locations were
measured using real-time continuous radon monitor RAD-7 detector together with
estimating the corresponding female and male organ doses using Monte Carlo (MC)
simulation software at Al- Najaf city-Iraq . 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 for male reveal that the bladder received the highest dose at
9.78E-05 μGy/h in Missan, while the salivary gland was noticed to have the highest
dose in each of Jmhorria, Adalh, Saad and Milad regions with dose rates of 4.65E-05,
3.59E-05, 5.72E-05 and 3.45E-05 μGy/h respectively. In Asskry Najaf regions the
highest dose was seen to be with the Lung with 9.30E-05 μGy/h. In Asskiry Kufa and
Mutnaby the highest organ doses were attributed to the bone surface at 9.73E-05 and
9.62E-05 μGy/h respectively. In Tmoz and Sirai regions, the highest organ doses were
with Extrathor airways and thyroid at 6.64E-05 and 9.65E-05 μGy/h respectively. By
contrast, the female findings reveal the doses for all organs and across all considered
neighborhoods ranged from 1. E-04 μGy/h to 9E-05 μGy/h. Finally, it can be concluded
that all results of radon concentrations in ten locations samples were within the range
allowed according to ICRP. The organ doses seem to be very low which in turn reduce
the concern realted to the effect of radiation.
