| Abstract | ||
| The current study was conducted in some parts of Nineveh province, and through the implementation of a radiation survey of 29 locations using the site Geiger-Mueller detector and find a mathematical equations to describe the relationship between the absorbed dose rate (μGy / hr) and the count rate (count / s). We have used three radioactive sources ( Co60, Cs137, Na22 ) with activity of 1µCi for each one to calibrate the Geiger-Mueller detector. The study revealed that the use of a source of Cs137 is the best source for the calibration of detector. the natural background radiation limits for these locations were found that to be about (0.019 mR / hr). we found that the highest dose rate were (0.22 μGy / hr) in Qaraqosh location and the lowest dose rate were (0.151 μGy / hr) in khazir location. | ||
