Materials and Methods: Samples of soil were collected from locations around the Kufa cement factory in Najaf city of Iraq that are about 10 km²&nbsp;away from the center of Najaf city. They were analyzed to set the concentrations of natural radioactivity samples of ⁴⁰K,²³⁸U and ²³²Th. Results: The specific activity values of ⁴⁰k, ²³⁸U and ²³²Th varied from (378.54&plusmn;11.39 to 2404.27&plusmn;26.13)Bq/kg, (15.51&plusmn;5.88 to 106.08&plusmn;7.35) Bq/kg and (1.80&plusmn;3.41 to78.19&plusmn;3.05) Bq/kg continually. Conclusions: Results demonstrate that the convergences of radiation and doses due to radionuclides in the overviewed area are higher than the safety field of the worldwide average (UNSCAR 2000). Almost all of the radiological parameters are inconsequential to cause any dangerous health problems to people living in the area.</div> Radioactivity in soil samples around Kufa 1035 1040 http://ijrr.com/browse.php?a_code=A-10-1-897&slc_lang=en&sid=1 L.A.
