Determination of Linear Attenuation Coefficients of Materials by Using Timing Method

In this work, gamma-ray linear attenuation coefficients of aluminum (Al) and lead (Pb) materials were determined by using timing method. The used setup is different from the conventional ones. The goal of the presented setup is the fact that it is used the timing technique. The detection system is composed of a 3''x3'' NaI(Tl) inorganic scintillation detector and related equipment together with 137Cs and 60Co radioactive sources. Obtained results are in good agreement with each other.
