近年来,放射治疗已成为一种较为常用的治疗方法。钻治疗机和直线加速器等放射性医疗设备在医院已被使用。为了达到完备、可靠的防护条件,设备的关键部位和病人不需要照射的器官都必须采用具有性能可靠、体积小、易于加工、价格便宜的各种形状屏蔽件,如放射源的贮藏罐、防护板等。高比重钨合金是一种较为理想的材料,现介绍如下。一、高比重钨合金主要性能 1.化学成分
In recent years, radiation therapy has become a more common treatment. Radiological medical equipment such as drilling machines and linear accelerators have been used in hospitals. In order to achieve complete and reliable protection conditions, critical parts of the equipment and organs that the patient does not need to irradiate must be shields of various shapes, such as radioactive sources, which are reliable, small in size, easy to process and inexpensive, Board and so on. High proportion of tungsten alloy is a more ideal material, are presented below. First, the main features of high proportion of tungsten alloy 1. Chemical composition
