本文介绍的QD50—1型移动式X线机加装防护装置,从立位测试平面的数据看,如排除测量仪器校准误差及测量的偏差,基本能达到卫生部颁布的立位测试平面5mr/h的要求,且有防护效果好,制作简单,成本低的优点。但应注意,QD50X线机有不少工厂生产,对机头采用防护方法不尽相同,有的漏散射线较多,有的较少。使用者可请当地防疫站等单位协助测量,以根据实际情况,采取相应措施为宜。另外,在机器增加防护装置后,必然增加立柱横臂的承重量,随之带来的扭、压、拉力的增加,可使机器发生机械变形及磨损等情况,也应加以考虑。
This article describes the installation of QD50-1-type mobile X-ray protective device, from the vertical test plane data, such as excluding the calibration error of measuring instruments and measurement of deviation, the basic can reach the Ministry of Health issued a vertical test plane 5mr / h requirements, and protective effect is good, simple production, low cost advantages. However, it should be noted that there are many factory production QD50X line machine, the use of protective methods for the nose are not the same, some leakage scattering more, and some less. Users may ask the local epidemic prevention station and other units to assist in the measurement, according to the actual situation, appropriate measures to be taken. In addition, increased protection devices in the machine, will inevitably increase the column transverse arm bearing capacity, along with the resulting twist, pressure, tensile increase, the machine can cause mechanical deformation and wear, etc., should also be taken into account.
