Determination of Linear Attenuation Coefficients of Materials by Using Timing Method
Instrumentation Science & Technology, 2009 Abstract 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.
