Abstract: In this work, radon concentrations (²²²Rn) for smokers in the Najaf Governorate /Iraq in some biological samples (serum of blood and urine) were measured using a RAD-7 detector (Durridge Company Inc, made in the USA). Fifty samples of serum blood (twenty-five (25)) and urine (twenty-five (25)) were collected for smokers and people aged (21-70) years for all samples. Samples were classified into five age groups (21-30), (31-40), (41-50), (51-60) and (61-70) to compare the results and determine their effects on the radon concentrations. The average value of radon concentrations in (Bq/m³) unit was (11.82±3.81) in serum samples, while in urine samples was (11.96±6.01). The results and comparisons indicate that radon concentrations depend on the variables on which this study was based. By comparing the radon concentrations for serum and urine with the age groups, the p-value was increased significantly statistically. Also, it was found that there is a positive and good correlation for radon concentrations between serum and urine. Therefore, it can be concluded radon concentrations were within the limits allowed globally, and thus, serum and urine were free from environmental pollution.
