Estimation the dose on radiosensitive tissue for women in dwelling and health risks caused to reduce the fertility women and cancer in gonads in Iraqi Kurdistan regions.

Abstract

Present work, described the risk of indoor radon  concentration on the women ?s body tissue, such as  bladder, gonads, and uterus.  Minimum and  maximum annual effective dose A. E. D. to  uterus and many tissues were found  2.39 m Svy^-1 and 32.28 mSvy^-1,  respectively. The lowest radon concentration detected was found in the living room   94.883 Bq m^-3, and the highest radon concentration detected was found in the kitchen  364.412  Bq m^-3. The distribution of indoor radon concentration was high in many houses and many pose health risk affected on women fertility causative the infertility and cancer in gonads. The large variation of the indoor radon activity between different dwellings can be explained depending on the age of the house, ventilation conditions and the type of building materials, nature of the soil underneath, and geological considerations.  Majority of the houses had poor ventilation attributed to the absence of ventilators.  Dose is higher in old houses than in new ones because the ventilation rates in new houses are higher than those in old houses. The results showed significant difference ( p value  <  0.001) found between kitchen and living results, where concentration of radon in kitchen had higher results medians than results of living. Significant difference ( p value  <  0.001)  found among organs in living room, where the gonads are the organ with highest concentration while bladders were the lowest,  also significant difference ( p value  <  0.001)  found among participants organs in kitchen room

Key words: Infertility, gonads cancer, indoor radon, human risk, CR-39NTDs, annual effective dose.
