Clay, consisting fine-grained minerals, is an interesting materials and can be used in a variety of diferent fields especially in dermatology application. Using clay such a field it is important to measure its natural radioacitivty. Thus the purpose of this study is to measure 226Ra, 232Th and 40K concentration in clay samples enriched with boron. Three different types of clay samples were prepared where boron is used in different rate. The measurements have been determined using a gamma-ray spectrometry consists of a 3 ″×3 ″ NaI(Tl) detector. From the measured activity the radium equivalent activities (Ra eq), external hazard index (H ex), absorbed dose rate in air (D) and annual effective dose (AED) have also been obtained. © 2011 American Institute of Physics.
