Measurement of Radon -222 Concentration Levels in Spring Water in Iraq

This work describes the results of measurements on the concentrations of radon (222Rn) found in seven mineral water samples collected from some natural mineral springs at seven sites in Nenevah governorate of north region in Iraq. Heat drying method was used to concentrate the radioactive nuclides in measured samples. Test tubes technique employed to measure (222Rn) using (CR – 39) plastic nuclear track detectors. The activity density of (222Rn) ranges from (3.82 PCi /L) to (9.999 PCi / L); while the average value was (5.8054 PCi / L). All results were below the maximum contaminant level (MCL) for (222Rn) in drinking water as reported by Environmental Protection Agency (EPA).
