Abstract
In this research different samples of Iron Ore in Shams Abad Iron mine have been investigated. The samples included different compositions of iron ore that the most of them are hematite, limonite, siderite and goethite. The samples were taken from depth parts of the mine and after Preparation and expiration equilibrium time, the specific activity of natural radionuclides were determined using gamma ray spectrometry method with employing high purity germanium detector (HPGe) with 30% relative efficiency. The activity concentration of 226Ra, 232Th and 40K in these samples varied from 9.39±0.53 to 271.70±1.84,
