旅客运输机与直升机座舱微波辐射调查及其卫生学标准的探讨

Investigation of Microwave Radiation Intensity in Cabin of Passenger Aircrafts and Helicopters and Discussion on its Hygienic Standard.

为了解中国旅客运输机与直升机座舱微波辐射的现状并为制定民航行业卫生标准学提供科学依据，对国内５种旅客运输机型（Ｂ７５７、Ｂ７６７、ＭＤ８２、Ａ３００和Ｙ７）和三种直升机型（米８、Ｓ７６和贝尔２１２）座舱微波辐射的情况进行了调查。结果发现微波辐射强度旅客运输机为０．０５～６．０３μＷ／ｃｍ２，直升机为０．０４～８．６１μＷ／ｃｍ２，驾驶舱内高于客舱内。建议以＜１０μＷ／ｃｍ２作为中国旅客运输机与直升机座舱微波辐射的卫生学标准。

To evaluate intensity of microwave radiation in aircraft cabins and to provide data for drafting hygienic standard of microwave radiation,an investigation of microwave radiation intensity in the cabin of five types of passenger aircraft (B757,B767,MD82,A300 and Y7) and three types of helicopters (MI8,S76 and Bele212) were carried out from June to December,1994.The results showed that microwave radiation intensity in the cabins of passenger aircraft and helicopters were 0.05～6.03μW/cm 2 and 0.04～8.61μW/cm 2,respectively.The intensity of microwave radiation was higher in the cockpits than in the passenger cabins.There was difference among various types of airplanes and helicopters.After reviewing hygienic standards of microwave radiation domestic and abroad and hygienic situation of investigation,10μW/cm 2 was proposed as the upper limit of microwave radiation in the cabins of passenger aircraft and helicopter.
