Abstract: In recent years, low level radioactivity measurements of radionuclides, especially the long-lived radionuclide 137Cs (t1/2=30.1 y) in the environmental samples have an increasing importance due to the global fallout originating from atmospheric contamination caused by nuclear weapon tests and nuclear accidents (after Chernobly accident). In addition, a need has arisen to find and produce materials containing low in radioactive promordial elements thorium, uranium and potassium since these materials, in particular, cement, clays and ash fly from the coal-fired thermic power plants are widely used in several mass-production industrial applications such as for the making concrete, bricks, seramics. In this work, the radioactivity measurements of 238U, 226Ra, 232Th, 40K,134,137Cs and other radionuclides in environmental and industrial samples such as soil, coal, ash fly, cement, etc. were measured routinely by using high resolution gamma-ray spectrometry, after a method validation by IAEA proficiency tests within a QA/QC program by IAEA RER/2/004 project, in Ankara Nuclear Research and Training Center in Turkey. The gamma-spectrometric method employed is described and the analysis results for various samples are given in this paper.
