In this work, measurements of indoor radon concentrations were completed for selected dwellings in Baghdad governorate using DURRIDGE RAD7 detector. The spectra measured by this detector demonstrated that, the radon concentrations were changed from 89 Bq/m 3 (Hay Ur district) to 191 Bq/m 3 (Al-Mansour district) with an average value of 123.3±24.3 Bq/m 3 which is below the recommended range (200-300 Bq/m 3 ) given by (ICRP, 2009). All other studied parameters such as EP, PAEC, AED and CPPP their values were less than or corresponding to the allowed worldwide average values.

Lung cancer is considered a disease that is completely happened by smoking; therefore, it is preventable perfectly. Yet, a small percentage of cases is there, possibly as many as 5 to 15%, in which there are other reasons. The risk factors acknowledged for the other groups comprise passive smoking, family history of cancer, occupational expo sure to certain chemicals and ionizing radiation, and diet. Moreover, a fifty samples from the dwelling of lung cancer patients were compared with twenty healthy volunteers. The study aims at identifying the dangers of radon gas in the dwelling of infected patients and the control group, clarifying how it contributes to increasing the risk of lung cancer. To achieve the aim of the study, the researcher used nuclear track detectors CR-39 , baguettes and TASLIMAGE System . Keywords: Lung cancer, CR-39 Detector, Radon gas for dwellings, Iraq.

“…The average concentration of soil gas radon in the city of Karbala is lower than that of 6.71 kBq/m 3 in Saudi Arabia 11 Considering the great importance of radon as a result of the health effects on human life, many researchers in various countries around the world conduct research and studies to measure the concentrations effective dose of it in the air of houses of those countries in order to reduce the risks resulting from it and develop the necessary solutions to it through special programs. By comparing the findings of the current research with the findings of local and international studies, we noticed that the concentrations of radon in the air of dwellings of the city of Karbala were lower than the concentration of radon in the air of both Iraq's houses 18…”

Introduction: The radon isotopes are not as significant as (222Rn) due to the decay of the natural radionuclides (235U), (232Th) and (238U) due to their short half-life, at most. (222Rn) can be classified as among the most harmful radioactive elements in the world. Material and method: In this analysis, the closed-can technique was used with solid-state nuclear track detectors (CR-39). After forty days of closed dosimeter buried in the soil of the garden, and ninety days from the closed position in the air of some dwellings were collected dosimeter and stripped of nuclear detectors impact of closed groups. For 8 hours, CR-39 detectors were chemically etched by (6.25 N) NaOH solution at 70°C and then registered within an optical microscope. Result: The levels of soil radon concentrations ranged from 28.44±0.58 to 479.76±2.43 Bq/m3 with a mean value of 220.33±1.64 Bq/m3, while the concentration of radon in the air of certain dwellings varied from (1.95±0.27 to 46.82±0.75) Bq/m3 with an average value of 21.51±0.54 Bq/m3. In comparison, the annual effective dose attributed to radon in soil ranged from 0.71±0.09 mSv/y to 12.10±0.38 mSv/y with an average value of 5.55±0.261 mSv/y, while the annual effective dose in air differed from (0.04±0.02 mSv/y) to (1.18±0.12 mSv/y) with an average value of (0.60±0.09 mSv/y). Conclusion: Neglecting the effects of other radon sources, the percentage share of the annual effective dose due to radon in soil measured in the air home, ranged from 0.005±0.001 to 0.453±0.074 with an average value of 0.130±0.040. Weak correlation between concentrations of radon in households and soil air. But roughly speaking, one can say that in soil air every 1000 Bq/m3 and 1000 mSv/y contributes around 130 Bq/m3 and 130 mSv/y in indoor air.
