Abstract:

 Radioactive materials, containing high-count rate, are found in some areas in the world which have worldwide use as construction and facing material. The radiation doses, in the Garmik area, are about 268.6 nGy h-1, which are density population by residents of ten of villages and two towns.
     The outdoor terrestrial gamma-ray background in some region of Garmik area was studied in order to determine the absorbed gamma dose rates of the soils and rocks. Gamma ray spectra have been recorded using the advance nuclear measurement system (digital spectroscopy analyzer DSA with NaI (TI) detector). This method is very suitable for measuring outdoor gamma radiation dose because the gamma count and human -radiation exposure will not be lost by the method by which the whole radiation exposure has been determined.  A new equation has been formulated for this method. The total dose rates inside Sulaimani city was (42.873) nGy h-1 considered as a normal local outdoor dose rate (background).
     The average values of outdoor dose rates of the studied samples, in Tatan, Hangazhal and  Garmik areas  have been found to be (226.1005, 257.477,322.541) nGy h-1 respectively. These values are nearly 6 times grater than the normal local outdoor dose rate of the background of Northeastern Iraq. The dose rate of each radioactive elements or isotopes have been determined for each spectrum of each mentioned area which are equal to 8.4554, 67.0995, 66.9057, 50.6143 nGy h-1 for Sulaimani city, Tatan, Hangazhal and Garmik respectively. The total rate of radionuclide is about 22.76% of total outdoor dose rate.
