目的：阐明低功率密度毫米波辐射孕鼠是否导致胎仔生后精神生理学方面的改变。方法：用频率３６．１１ＧＨｚ、功率密度７．２ｍＷ／ｃｍ２、１０．０ｍＷ／ｃｍ２的毫米波，在ＢＡＬＢ／ｃ小鼠怀孕６～１５天时每天辐射２小时，用生后精神生理学指标进行分析。结果：７．２ｍＷ／ｃｍ２的毫米波辐射导致出生３天内的胎仔体重降低及成年子鼠学习和记忆能力降低；１０．０ｍＷ／ｃｍ２的毫米波辐射导致生后仔鼠３项反射指标形成时间明显延迟，胎仔生后１天～８周时体重明显降低，成年子鼠学习和记忆成绩降低，且明显低于７．２ｍＷ／ｃｍ２毫米波组鼠。结论：毫米波辐射植入后期胚胎可导致仔鼠精神生理学指标的变化，增加毫米波辐射的功率密度可加强对胚胎的毒性效应。
OBJECTIVE: To elucidate whether the low-power density pregnant mice exposed to millimeter waves lead to changes in psychophysiology after birth. Methods: BALB / c mice were irradiated with millimeter waves with frequency of 36.11GHz and power density of 7.2mW / cm2 and 10.0mW / cm2 for 6 hours everyday after 6-15 days of pregnancy, and then analyzed with postnatal psychophysiological parameters. Results: Millimeter wave radiation of 7.2 mW / cm2 resulted in a decrease of fetal weight and development of learning and memory of adult offspring within 3 days of birth. The millimeter wave radiation of 10.0 mW / cm2 resulted in significant formation of 3 reflexes Delayed, fetus 1 day to 8 weeks after birth significantly reduced body weight, adult learning and memory performance decreased, and significantly lower than the 7.2mW / cm2 millimeter wave rats. Conclusion: The implantation of millimeter wave radiation in late embryos can lead to changes in psychophysiological parameters of offspring. Increasing the power density of millimeter wave radiation may enhance the toxic effect on embryos.
