最近,我们对某职工医院的一台WBJ～1型微波理疗机的安全防护措施(屏蔽围帐和屏蔽罩单),进行了测试.其微波辐射的功率密度低于卫生部和四机部的暂订卫生标准,屏蔽效率为9.4～24.6dB,对周围的医护人员、患者本身的非治疗部位达到了安全防护的目的,防止了对环境的污染.现介绍如下: 一、防护措施的概况 WBJ—1型理疗机,为临床上常用的理疗机之一,频率为2450兆周,辐射器的输入功率为120
Recently, we conducted a test on the safety precautions of a WBJ-1 microwave physiotherapy machine in a worker’s hospital (shielding bays and shielding bins), and its microwave power density is lower than that of the Ministry of Health and the four-machine Tentative health standards, the shielding efficiency of 9.4 ~ 24.6dB, to the surrounding medical staff, the patient’s own non-treated parts to achieve the purpose of safety and prevent the pollution of the environment are as follows: First, an overview of protective measures WBJ -1-type physiotherapy machine, clinically used as one of the physical therapy machine, the frequency of 2450 trillion weeks, the radiator input power of 120
