几种家用电器电磁辐射的测量及其安全距离

Measurement and Safe Distance of Electromagnetic Radiation of Household Electrical Appliances

目的通过测量微波炉、电磁炉、电饭锅、节能灯、洗衣机、液晶电视、电冰箱、电扇、电脑等几种家用电器的电磁辐射,提出其使用的安全距离。方法使用LZT-1000型电磁辐射测试仪测量家用电器不同距离的电磁辐射。结果使用中的微波炉在1.6 m以上、电磁炉在1 m以上,没有金属外罩的微风吊扇在0.8 m以上才具备符合国家标准的电磁辐射,笔记本电脑和台式电脑也存在不同程度的电磁辐射。结论几乎所有家用电器都有或多或少的电磁辐射,应注意保持安全距离,并对辐射较大的电器减少使用时间。

Objective By measuring the electromagnetic radiation result from household electrical appliances like microwave oven, induction cooker,electric rice cooker, energy-saving lamps,refrigerators,washing machines,liquid crystal TV,electric fan,and computer,the method for the safe use is present to reduce and avoid the impact of their electromagnetic radiation.Method The electromagnetic radiation from the household electrical appliance at different distances was measured by LZT-1000 electromagnetic tester.Results The safe use distance for the microwave oven was more than 1.6 meters,for induction cooker was more than 1 meter,for ceiling fans without metal casing breeze was more than 0.8 meters according to national standards of electromagnetic radiation.The electromagnetic radiation from computer was also noticed.Conclusion There is electromagnetic radiation in almost all home electrical appliances,which suggested pay attention to keep it a safe distance.
