A study of the use of palm fiber and palm shell as a thermal neutron radiation shielding material
Preliminary studies have been conducted to determine the benefits of using palm fiber and shells as thermal neutron radiation shielding materials. The method in this research using Neutron Activation Analysis (NAA). However, based on the results of SEM-EDX data analysis, it was found that palm fiber...
