We have studied ultra-weak photon emission (UPE) from living organisms. We report here some features of the UPE from human hand by means of photon counting techniques. The intensity of the UPE depended on the position of human hand; nail>finger>palm. As the temperature declined, the intensity of the UPE from the palm decreased. Further, as oxygen concentration around the palm was lowered, the intensity of the UPE from the palm decreased. These results show the UPE from the palm partly contains emissions based on oxidation reaction on skin surface as a potential. When we used mineral oil between the photomultiplier tube and the palm, the intensity of the UPE increased twice as much, which indicates the UPE from the inside of the skin certainly exists. The fact may be explained by refractive index matching. As mentioned above, we considered the generation mechanism of photons emitted from the human hand.
我们研究了生物体的超微弱光子发射（UPE）。在此，我们通过光子计数技术报告了来自人手的超微弱光子发射的一些特征。超微弱光子发射的强度取决于人手的位置；指甲＞手指＞手掌。随着温度下降，手掌的超微弱光子发射强度降低。此外，随着手掌周围氧气浓度降低，手掌的超微弱光子发射强度也降低。这些结果表明，来自手掌的超微弱光子发射部分包含基于皮肤表面氧化反应作为一种电位的发射。当我们在光电倍增管和手掌之间使用矿物油时，超微弱光子发射的强度增加了两倍，这表明来自皮肤内部的超微弱光子发射确实存在。这一事实可以通过折射率匹配来解释。如上所述，我们考虑了从人手中发射的光子的产生机制。
