Study on Human Stress Reaction Caused by ELF Electric Field Exposure

通过本研究，为达到这一目的，本研究从以下几个方面进行了探讨。研制了测量人体在不同环境条件下非接触时的电场感知阈值和生理变化的设备。(1)研制了可在人体内放置和测量的恒温恒湿装置。(2)设计并制造了可对部分人体进行电场照射的交流电场曝光器。(3)设计并制造了测量电场暴露部位附近血流变化的装置。测量暴露交流电场时的感觉阈值，以及在下列情况下的血流变化。(1)当电场暴露在对皮肤感觉刺激敏感的部位时，例如人的手和手臂。(2)对身体表面条件不同的受试者进行电场暴露。…更多地(3)对心理状况不同的受试者进行电场暴露。研制了测量人体非接触电场暴露时的感知阈值和应激反应的设备。(一)以确认对人体安全的潜在医疗机器为中心的设计设备。它制造的。(2)设计实现人体头顶、面部、手臂、腿部等体表侧面及电场照射附近血流变化的遥测装置。它是制造的。测量在下列条件下进行全身电场暴露时的知觉阈值和应激反应。(1)在不同的暴露和环境条件下对不同数量的受试者进行测量，如性别、年龄和人体毛发的数量，它们是多个受试者。通过反复收集和统计分析，得出以下研究结果。人体调查显示，暴露在电场中会改变血液流量。此外，还验证了这些变化受相对湿度、直流交换电场和测量部位的差异、不同的身体表面状况和精神状况的影响。我认为，这些结果大多达到了对电场生理功能的分析，这一假说被挂起作为本研究的目的。较少

By this research, in order to attain the purpose, it inquired in the following ways.1. Development of equipment which measures human perception threshold of electric field and physiological change in un-contacting on different environmental conditions. (1) the constant temperature and humidity equipment which puts in bodily and makes measurement possible was manufactured (2)AC electric field exposure equipment that enables electric field exposure of some human bodies was designed and manufactured. (3) The equipment which measures the blood-flow change near the electric field exposure part was designed and manufactured.2. Measure the perception threshold at the time of exposing AC electric field, and blood-flow change under the following conditions. (1) When electric field exposure is carried out to a portion sensitive to cutaneous sensation stimuli, such as a man's hand and an arm. (2) When electric field exposure is carried out to the subject from whom body surface conditions differ. … More (3) When electric field exposure is carried out to the subject from whom mental conditions differ.3. Development of equipment which measures perception threshold and stress reaction at the time of carrying out electric field exposure in un-contacting on whole human body. (1) Design equipment centering on the potential medical treatment machine with which the safety to a human body is confirmed. It manufactured. (2) Design the equipment which carries out telemetering of blood-flow change of the body surface side of human bodies, such as the top of the head, a face, an arm, and a leg, and near the electric field exposure. It manufactured.4. Measure the perception threshold and stress reaction at the time of carrying out whole body exposure of the electric field under the following conditions. (1) Measure under different exposure and environmental conditions to the subject of different a large number, such as a sex, age, and quantity of human body hair, and they are many subjects. It received and analyzed statistically repeatedly.The following research result was obtained by the above experimental research. Survey by the human body showed that a blood flow changed by electric field exposure. Moreover, it checked that these change influenced according to the difference between relative humidity, and direct-current exchange electric field and a measurement part, various body surface conditions, and mental conditions. I think that these results have attained mostly the analysis of the physiological function of electric field about the hypothesis hung up as a purpose of this research. Less
