Due to the ever-increasing complexity of treatment modalities in radiation therapy, there has
been a greater need for detectors to perform quality assurance to ensure patients are treated …

This study aims to reduce the uncertainty about the photoneutron dose produced over a
course of radiotherapy with high-energy photon beams and evaluate photoneutron …

Objectives: Linear accelerators operating at or above 10 MV produce neutrons by
photonuclear reactions and induce activation in machine components, which are a source of …

In this study, the neutron contamination due to the 2300C/D Varian medical linac has been
calculated by using the long counter. In doing so, the energy response of the long counter in …

Conventional linear accelerators (LINACs) for radiotherapy produce fast secondary neutrons
due to photonuclear processes. The neutron presence is considered as an extra undesired …

Objective: Undesired neutron contamination imposed to patients during treatment is among
the main factors increasing the risk of secondary cancer in radiotherapy. This additional …

Passive Solid State Nuclear Track Detectors (SSNTDs) are a versatile tool for neutron
studies as has been shown long ago and several good quality materials are commercially …

Background: One of the main causes of induction of secondary cancer in radiation therapy is
neutron contamination received by patients during treatment. Objective: In the present study …

CR-39 solid-state nuclear track detectors (SSNTDs) were used to study the variations of fast
neutron relative intensities around a high-energy (23 MV) linear accelerator (Varian 21EX) …

Background and purpose: High-energy photon beams above 8-10 MV used in external
radiation therapy produce neutron in dealing with the linear accelerator components and …
