The current research aims to compare some of the indicators of radioactive contamination, contained, absorbed dose (D), radium equivalent, (Raeq), index of external and internal radiation hazard, (Hex , Hin ), and gamma activity concentration index, (Iγ), in five soil samples unfertilized and other five fertilized with Iraqi origin fertilizers, to find the effect of fertilization on how much increases the radioactive contamination, the concentration of radioactive elements 226Ra,232Th and 40K in these samples estimated by using gamma ray system NaI (Tl). It has been reached that the values of indicators of the fertilized and unfertilized soil that the rate of absorbed dose 0.0819 μSv / h and 0.133 μSv/h, radium equivalent 138.56 Bq / kg and 319.31 Bq / kg, gamma activity concentration index, (Iγ) 0.987 and 2.23, the internal radiation hazard index 0.488 and 1.326, the external radiation hazard index 0.374 and 0.862 ,respectively. The surface exaltation rate of 222Rn was estimated after finding the radon concentration by using nuclear track detector CR-39, the emission from the soil surface in general was less than the recommended value by UNSCEAR
