Radon concentration measurements were performed in all 24 samples of ground water at four locations in Al-Haidariya hand in Najaf, Iraq, using active RAD-7 continual radon measuring instruments. The radon concentrations were measured at different time (0, 24, 48, 72, 96 and 120) hour for determining daily correction factor in groundwater samples using the least-squares fitting method. The experimental results show that the radon concentration at low and high time of measuring for all location in this study were varied from (1130±220 to 443±96.54) mBq/l at (l location), from (1180±184 to 339±66.14) mBq/l at 2 location, from (1049±166 to 542±90.65) mBq/l at 3 location and from (1270±190 to 625±86.32) mBq/l at 4 location, therefore the radon concentration increased with decrease time of measuring samples. The main finding of the least-squares fitting method investigation is that use present study, experimentally observed, the radon concentration can be determined theoretically by depending on the semprical formula which it was determined at different location. This study proved that can be determined radon concentrations in water using RAD-7 detector at any day of measurement depending on the daily correction.
