Neutron production and transport at a medical linear accelerator
The Colorado State University Veterinary Teaching Hospital (VTH) uses a Varian Trilogy™ linear accelerator (linac) for radiation oncology treatment. The high-energy electron beam is used to treat superficial tumors (deep tissues are spared with this modality) or is accelerated against a target to produce high-energy photons that are used to treat deep seated tumors (skin is spared with this modality). Either application might exceed the neutron production threshold for various materials. This study evaluates neutron production and transport in the environment surrounding the VTH trilogy through ...
