Study on Human Stress Reaction Caused by ELF Electric Field Exposure

通过本研究，为了达到研究目的，主要从以下几个方面进行了探讨。研制测量不同环境条件下人体对电场的感知阈值及非接触时的生理变化的仪器。(1)研制了可置于人体并使测量成为可能的恒温恒湿设备(2)设计制造了可使部分人体暴露于电场的交流电场暴露设备。(3)设计制造了电场暴露部位附近血流量变化测量装置。测量接触交流电场时的感知阈值，以及血流在以下条件下的变化。(1)当电场照射到对皮肤感觉刺激敏感的部位时，如人的手和手臂。(2)对体表条件不同的被试进行电场暴露时。(3)当对精神状况不同的受试者进行电场暴露时。在非接触状态下对人体进行电场暴露时的感知阈值和应激反应测量设备的研制。(1)以确定对人体安全的潜在医疗器械为中心设计设备。它制造的。(2)设计遥测人体体表侧，如头顶、面部、手臂、腿部及靠近电场暴露处的血流量变化的设备。manufactured.4。测量在以下条件下进行全身电场暴露时的感知阈值和应激反应。(1)测量在不同的暴露和环境条件下给受试者不同的大量，如一个性别、年龄和人体毛发的数量，他们是许多受试者。反复接收和统计分析。通过上述实验研究，得到以下研究结果：人体的调查表明，暴露在电场中会改变血液流动。并根据相对湿度、直流交换电场与测量部位的差异、各种体表状况、心理状况等对这些变化的影响进行了检验。我认为，这些结果已获得的分析大多是关于电场的生理功能的假设挂作为本研究的目的。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
