A Different Method to Determine the Gamma-Ray Linear Attenuation Coefficient
Assist. Prof. Elif Ebru Ermiş
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. Obtained results were compared with those of XCOM program and literature values.
