摘要
利用红外热图技术,在三种辐射条件下观察了30只Wistar成年大白鼠吸收超短波辐射能量后,各部位体表温度变化。结果表明:大白鼠各部位体表温度,受超短波辐射后,呈现明显的频率效应。300MHz辐射频率比40.68MHz辐射频率有更显著的能量吸收。睾丸部位与其它部位相比,明显地表现出对超短波能量吸收的敏感性,辐射前后的温度变化有极显著意义。实验结果还表明:肛温和体表温度有很好的一致性。在40.68MHz和300MHz复合频率作用下,大白鼠对射频能量的吸收比单一频率辐射作用时更为显著,表现出明显的致热效应。
Body surface temperature changes of 30 white adult wistar rats exposed to ultra-
shortelectromagnetic wave under three experimental conditions were observed with infrared hot
map.The main purpose of the present study is to reveal the hazard of ultra- short wave to the
organisms in order to provide necessary data for working out a related safety standard. The
results showed that the tem-perature changes on rat’s body surface are obviously related to
frequencies of the electromagnetic radia-tion. The energy at 300 MHz is more readity absorbed
by the rats than at 40.68 MHz. The tempera- ture changes of the rat’S testes are most
sensitive as compared with other parts of the rat’s body. The results also showed temperature
changes at the rat’S anus are similar to those at body surface.The en-ergy absorbed by the
adult white rats exposed to radiant energies at 40.68 MHz and 300 MHz at the same time has
more evident calorific effect than that at single frequency.
