目前,国内对GX—PAN型牙科全景X线机的防护设备尚处空白。 众所周知,任何辐射效应对人类都是有害的。X线辐射亦不例外,GX—PAN型牙科全景X线机是利用X线形成图像进行诊断的,在给人类牙科保健带来利益的同时也给利用其检查牙科疾病的被检者带来了机体的危害。 医学统计证明,眼部受到一次或短期大剂量外照射或长期累积受照剂量达2Gy以上时可引起放射性白内障。 At present, the protective equipment of the GX-PAN dental panoramic X-ray machine is still at a blank in China. As we all know, any radiation effect is harmful to humans. X-ray radiation is no exception. The GX-PAN dental panoramic X-ray machine uses X-rays to form images for diagnosis. It brings benefits to human dental health care and also brings to the people who use it to check dental diseases. The hazards of the body. Medical statistics show that when the eye is exposed to a large dose of external radiation for a short period of time or in a short period of time, or if the dose of long-term cumulative irradiation reaches 2 Gy or more, radioactive cataract may be caused.
