Current problems of nonionizing radiation.
本文讨论了射频电磁辐射在电信和电力传输等领域的广泛应用及其对生物体的影响，强调需要利用生物模型评估辐射机制和效应，为职业卫生标准提供依据。
Electromagnetic radiation in the radiofrequency range is the most common type of nonionizing radiation. The accelerated development in telecommunications and the introduction of power transmission lines, as well as glue drying and plastic heating in the wood and plastic industries, cause both occupational and nonoccupational systematic exposure to electromagnetic radiation in the radiofrequency range. For the hygienic rating of radiowave exposure it is necessary to use biological models to evaluate, in depth, the mechanisms and effects of electromagnetic radiation. The ultra- and superhigh frequency range is the most active in causing biological responses. The high frequency range is less active. Physical characteristics (continuous and impulse) and the combined effect of the electromagnetic field with other factors, eg, elevated air temperature, etc, have an effect on biological responses.
