医疗上使用了短波透热仪,工作频率为27.12MHz,它是通过把电磁能转换成热的方法来加热人体局部组织,达到治疗效果。然而,这种仪器具有电磁辐射。为减少操作人员在治疗过程中受到的辐射。本文作者对气适应器、双极适应器、单极适应器和环形适应器短波透热仪的电磁场强度进行了测量.对其场图的分析结果表明,气电极引起的有害辐射最强,而环形电极则为最弱。因此,正常情况
Medical use of shortwave diathermy, the working frequency of 27.12MHz, it is through the electromagnetic energy into heat method to heat the human body tissues to achieve the therapeutic effect. However, such instruments have electromagnetic radiation. To reduce the radiation received by the operator during treatment. The authors measured the electromagnetic field strength of gas adapters, bipolar adapters, monopole adapters and toroidal adapters shortwave diathermy devices.The analysis of their field plots showed that the most harmful emissions were caused by gas electrodes, The ring electrode is the weakest. Therefore, the normal situation
