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.

Effects of air pressure changes on gamma linear attenuation coefficient in the air

Journal of Science & Science Education, 2017
The measurements of gamma linear attenuation coefficient in the air at variance air pressure has been done. The measurements were performed to determine the effects of air pressure changes on gamma linear attenuation coefficient in the air. The measurements were used Co-60 as the gamma radiation source and LND 72 Geiger-Muller as the radiation detector
