项目摘要

近年,高圧送電線・各種の高出力電気機器など強力な電磁源が日常空間に現れ,我々は人類史上未経験の人工電磁環境にさらされている.各国でそれぞれ個別の安全基準が暫定的に設けられてはいるが,国によりその値が大きく異なっているのが現状である.その原因としては,生物学的および工学的根拠に基づく客観的評価法の欠如によるところが大きい.我々はこれまでの研究をとおし,人体のような複雑な構造に対する電磁界ならびに空間イオン流の曝露量の解析・評価法を確立してきた.またこれまでの動物実験の結果をもとに,電界感知閾値を指標としてヒトにおける影響を定量評価することを考えた.今年度はこれをさらに進め,交直両電界の生体影響の違いについて詳しい解析を行うとともに,電界感知に伴う生理的変化について調べた.まず,人工電磁環境の生体影響の定量解析をめざし,独自に開発した体表刺激反応計測法を用いてヒトに対する電界曝露実験を行った.その結果電界の生体作用の変化を,感知閾値の変化として定量化することができた.またこの定量解析をとおし,電界感知の主因である体表刺激作用が主として体毛の動きによって生ずること,その刺激作用が交流と直流で異なること,またその違いは相対湿度による閾値変化に比べると小さいことなどが明らかとなった.さらに曝露実験をとおし,感知閾値レベルの電界による体表刺激でも,人体に生理的変化をもたらす可能性を示唆する結果を得た.

In recent years, all kinds of high-output electric machines in high-speed transmission lines have been forced to operate magnetic sources for daily space operation, and we have not done anything in the history of artificial electro-magnetic environment. Each country has its own safety standard, and each country has set its own safety standards, while the country does not need to pay attention to the safety requirements. The cause of the disease, the root of biology, the root of engineering, the law of customers, is as bad as that of the general public. We use the method to analyze the exposure of space gas flow in the field of electricity and magnetism in the field of electricity and magnetics. make sure that the system is established. The results show that the electrical industry is aware of the impact of the environmental impact on the quality of the animal. There has been a rapid development in the field of medical science this year, and the industry is aware of the changes in physiology. In the artificial electro-magnetic environment, the quantitative analysis of the electrical and magnetic environment has been carried out, and the anti-statistical method of body surface stimulation has been independently used to expose the electrical industry. The results show that the effects of living organisms in the electrical industry are affected, and the effects of perception are quantified and quantified. In terms of quantitative analysis, the electrical industry perceives that the effect of body surface stimulation is mainly due to the effect of body surface stimulation, which is mainly due to the effect of body surface stimulation, which is mainly due to the effect of body surface stimulation, which is mainly due to body surface stimulation. The body surface irritation is sensed in the electrical field, and the possibility of physiological changes in the human body indicates that the results are successful.
