A method to determine the gamma-ray linear attenuation coefficient

In this work, gamma-ray linear attenuation coefficients of the materials such as Pb, Fe, Cu and Al were determined by means of traditional energy method and the developed timing detection technique. 1.33 MeV-energy radiation emitted from 60Co radioisotope was used in the experiments. The gamma-ray linear attenuation coefficient values of the materials were calculated by using Xcom code, and the experimental results were compared with the theoretical ones.

► Gamma-ray linear attenuation coefficients of some absorber materials was examined.
► Traditional energy method and timing detection technique were used.
► Timing method was successful in determination of the linear attenuation coefficient.
