Neutrons are produced in high-energy linear accelerator (linac) operating above 7 MV voltages. These secondary particles have high RBE and stored undesired dose in patients' body during the radiotherapy. In this study, it ...

Background: High-energy linear accelerator (linac) is a valuable tool and the most commonly device for external beam radiation treatments in cancer patients. In the linac head, high-energy photons with energies above the ...
