Co-60 gamma emitter was used as gamma radioisotope source. Regarding the gamma-ray transmission method, initial radiation intensity （I0） and radiation intensity （I） determined experimentally and [I/I0] rates were calculated and then density of materials could be determined by using Beer-Lambert Equation. Experimental application performed on widespread industrial metals or metal alloys e.g. lead, copper and steel, brass. With this study, it is shown that gamma transmission technique can be used for density measurements.展开更多

By gamma-ray spectrometry method, the average Radium （Uranium）, Thallium （Thorium）, Potassium and Cesium activity concentrations of totally 55 soil samples were measured as 23.35 ±1.40 Bqkg1, 14.55 ± 0.97 Bqkg-1, 242.36 ± 20.12 Bqkg-1 and 8.20 ± 0.68 Bqkg-1 respectively. There are a few values for the Uranium little bit up to the limit value of 33 Bqkgl. All values for the Thorium were lower than the limit value of 45 Bqkg-1. Only a few values for the Potassium were little bit up to the limit value of 420 Bqkg-1. Nearby the average for Hatay province is still under the limit value which were recommended by United Nations Scientific Committee on the Effects of Atomic Radiation （UNSCEAR）. By using these activities, ADRA and AEDE values were calculated to get the outdoor Terrestrial Gamma Dose.展开更多
