射频治癌是应用无线电频率的电磁波局部加热治癌的一种新疗法。它所用的机器功率较大,一般1～2kW,对现场的电磁辐射很严重;我室测试结果,漏能高出国内试用标准(或参考标准)数十倍以上(表)。而长期受高频辐射影响,可产生头昏、乏力、睡眠障碍、心悸、心前区疼痛等植物神经系统为主的症状,及心电图等改变;其中以微波的影响更甚,长期接触200μw/cm~2时上述症状明显,眼区受较大强度微波辐射可产生视力损害,以至发生白内障。因此对射频热疗机的电磁波辐射必须采取有效的防护措施。
Radio frequency cancer is the application of radio frequency electromagnetic wave local heating of a new treatment of cancer. It uses a large power machine, usually 1 ~ 2kW, on the scene of electromagnetic radiation is very serious; my room test results, leakage can be higher than the domestic trial standard (or reference standards) more than a few times (table). Long-term high-frequency radiation can cause dizziness, fatigue, sleep disorders, heart palpitations, anterior paresis and other autonomic nervous system-based symptoms and ECG changes; which even more affected by the microwave, long-term exposure to 200μw / cm ~ 2 when the above symptoms are obvious, the eye area by the greater intensity of microwave radiation can produce visual impairment, as well as the occurrence of cataracts. Therefore, radiofrequency thermotherapy machine electromagnetic radiation must take effective protective measures.
