High purity metal foils may be used for activation analysis in the determination of the energy spectrum of a neutron energy flux. The objective of this research is to determine the neutron environment around a linear accelerator (LINAC) beam head used in oncology treatments at Massachusetts General Hospital (MGH). This investigation will use an NaI scintillation analyzer to observe beta and gamma decays emitted from the irradiated metal foils. It is expected from previous simulation and comparison of equipment that the neutron flux will be on the order of and a mean energy between 100 keV and 500 keV [1]. For successful completion of this experiment, a range of energy resonances for neutron absorption must be observed. A kit of high purity foils must be purchased to accomplish this. This research will benefit students as it increases understanding of nuclide reaction chains, and develops experience in the entire investigatory process including design, rehearsal, setup, all the way through statistical analysis of results.
