摘要

光中子是高能医用x射线直线机与靶材、准直器以及治疗用x射线材料发生光核反应而产生的。这种光中子有时会产生有害的影响，在辐射防护和辐射控制方面是不可忽视的。本文简要说明了这种光中子产生的基本原理。总结了光中子引起的副作用。此外，还介绍了光中子的探测和测量技术。

[Basic Knowledge of Neutron: Generation of Neutrons Accompanied with the High-Energy Photon Therapy].

Photo neutrons are generated from high-energy medical X-ray linacs via photo-nuclear reactions with the materials of target and collimator as well as therapeutic X-rays. Such photo neutrons sometimes make unwanted influences and are not negligible for the aspects of radiation protection and radiation control. In this article, fundamental principle of such photo-neutron generation is briefly explained. The side effects induced by the photo neutrons are summarized. In addition, some techniques of the detection and measurement of photo neutrons are introduced.
