| Abstract: | According to the rule that when gamma rays pass through the matter,its strength decays complying with the exponential decay law,we choose the different materials to measure gamma rays' absorption coefficient.The results are exact and reliable.It is shown that the experiment is feasible for measuring the absorption coefficient of gamma rays through the different materials in laboratory. |
