Abstract: The aim of this study is to evaluate the level of natural and industrial radiation activity for soil samples of Al-Hawija Technical Institute which by using the High Purity Germanium detector (HPGe). It has been taken nine soil samples from Al-Hawija Technical Institute which located in Al-Hawija District-Kirkuk governate. The result showed that the specific activity concentration values (Bq.kg–1 unite) for radium 226Ra, lead 214Pb, lead 212Pb, Actinium 228Ac, Cesium 137Cs and potassium 40K and the calculation of the risk rates for radium equivalent 67.487 Bq.kg–1, effect concentration factor 0.496, internal risk factor 0.256, external risk factor 0.182, absorbing values dose in air 32.215 nGy. kg–1, internal annual effective dose values 0.158 mSv.y–1 annual effective external dose 0.040 mSv.y–1, increased risk of cancer 0.139×10-3, annual effective external dose 0.301 mSv.y–1 in all soil samples are lower than the average international value, so, the soils in these locals have no negative effect in human health or the environment.
