Abstract

A survey of industrial radiofrequency (RF) dielectric heaters within Australia was carried out during 1982 and 1983. The heaters operated within the frequency range 11-50 MHz and had available RF powers between 0.5 and 70 kW. The electric and magnetic field strengths in the vicinity of the operators of 101 heaters were surveyed. It was found that 39% of the heaters surveyed exposed the operators to levels greater than one but less than 10 times the recommended Australian limits. A further 23% of all heaters surveyed exposed the operators to levels equal to or greater than 10 times the recommended Australian limits.

摘要

1982年至1983年期间，对澳大利亚境内的工业射频（RF）介质加热器进行了一项调查。这些加热器工作在11 - 50兆赫的频率范围内，可用射频功率在0.5至70千瓦之间。对101台加热器操作人员附近的电场和磁场强度进行了测量。结果发现，在所调查的加热器中，39%使操作人员接触到的水平高于澳大利亚推荐限值的1倍但低于10倍。在所有被调查的加热器中，另有23%使操作人员接触到的水平等于或高于澳大利亚推荐限值的10倍。
