Energy loss caused by shielding effect of steel cage outside source tube

Energy loss caused by shielding effect of steel cage outside source tube 1 first-author 1 1 1 Shanghai University, Shanghai 200444, China Shanghai University, Shanghai 200444, China The energy loss, produced by shielding effect of steel cage outside the source tube, is quite considerable. With PENELOPE software package, MC results have been obtained based on the simulation of different source conformations. The result illustrates that the naked source tubes can improve the utilization ratio of the cobalt facilities. It demonstrates the applied value of the naked source tube in engineering.
