Neutron and high energy photon fluence estimation in CLINAC using gold activation foils

Abstract: The thermal neutron, epithermal neutron and high-energy photon fluence were measured in this work around the Varian 21EX 23 MV CLINAC, which is operated in Albairouni hospital in Damascus, Syria. Background: Photoneutron measurements around medical CLINAC aim to protect both patients and staff from unwanted radiation. Materials and methods: Neutron and photon activation techniques were applied using gold foils. Results: It was found that high-energy photons fluence has practically a constant value in the field… Show more

“…where C is the distance in z-coordinate from source to WF surface, L is half-length of WF for y coordinate, and Φ U = Φ 0 / (1 + z/F) 2 according to [30,31]. The source fluence is modified primarily for the dose-delivery depth z and secondly by the WF parameters [1-11, 20,21].…”
