A Different Method to Determine the Gamma-ray Linear Attenuation Coefficient

Instruments and Experimental Techniques, 2021
Gamma-ray linear attenuation coefficient values of Pb, Fe, and Al absorber materials were investigated. A fast coincidence timing measurement spectrometer was used for this purpose differently from other traditional spectrometers. A solid point 22Na positron source was utilized for the annihilation radiations.
