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

Abstract

Abstract 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 22 Na positron source was utilized for the annihilation radiations. Obtained results were compared with those of XCOM program and literature values.
