Photon Attenuation Coefficients of Iron Doped Clay at 662~keV

After discovery of the radioactivity by Becquerel, radiation started to be used in large fields and it became part of our life nowadays. Using radiation from industry to medicine brings its hazardous effect and radiation protection developed in physics in parallel with the utilization of radiation. Although time, distance and shielding are the main rules to be protected from radiation, shielding is most effective way. In this case development of shielding materials becomes important. Clay is an interesting material and besides using it for different purposes it can be used as plaster material in building construction. In this study iron doped into clay samples and radiation shielding properties has been measured at 662 keV gamma rays. The measurements have been performed using gamma spectrometer system which contains NaI(Tl) and 16k multichannel analyser.
