Abstract
The investigation of β- particle interaction with matter has many applications in nuclear industrial and medical science. In this work, we have impose different loads on Al-Mg-Zn alloy and Al metal sheets with different thickness to investigate the effect of elastic stress on the absorption coefficient of β- particles of 90Sr. Also, we have modulated and analyzed the loads on specimens, using ANSYS9 program to determine the distribution of stress within the specimens. The results show a valuable increase of µ -value due to loading the specimens by certain amounts of stress, where the µ- value decreases as the stress on the samples increases.
