目前,~(60)Co放射治疗机是我国治疗恶性肿瘤的一种常用医疗设备。放射源是具有强幅辐性的~(60)CO,常见的机械故障是钴源不能从放射位置(全开位)退回到贮藏位置(关闭位),这种现象俗称卡源。处理这种卡源的传统方法是用人工推撞回去,而给工作人员带来一定的辐射剂量。为了做好推钴源时的防护工作,我们自行设计安装了一种简易钻源复位装置。现介绍如下: At present, ~(60)Co radiation therapy machine is a commonly used medical equipment for the treatment of malignant tumors in China. The radioactive source is a strong radiation of 60 CO. A common mechanical failure is that the source of cobalt cannot be returned to the storage position (closed position) from the radiation position (fully open position). This phenomenon is commonly called the card source. The traditional method of handling this kind of card source is to manually push back and bring a dose of radiation to the staff. In order to do a good job of protecting cobalt sources, we have designed and installed a simple drill source reset device. The introduction is as follows:
