Comparative Analysis of G.M Tube Characteristics Using (Ba-133) Gamma Source and (Sr-90) Beta Test Source

The study is a recap of experimental physics which compares the G.M tube characteristics of (Ba-133) and (Sr-90) source respectively. SPECTECH ST360 Counter was used for this experiment. The test sources where placed 2cm and 4cm respectively in the counter window and voltage applied through starting at a potential of 780v. The counter was allowed to read for 60sec as the voltages was increased in step of 20v. Results obtained using Microsoft mathematics and further evaluations showed an effective performance of 22.16 % and 3.91% respectively for both the gamma and beta source.
