Abstract: [eng] [cze]
Spontaneous ultra-weak photon emission in the visible range was measured on palm and dorsal side of left and right hand by means of a low noise photomultiplier system. To study the dynamics of this photon emission in a 24h period photon emission was recorded in 2h intervals in 5 experiments. Mean photon emission over the 24h period differed both between subjects and hand locations. The fluctuations in photon emission in the course of 24h were more at dorsal sides than palm sides. Spontánní ultra-slabá emise fotonu ve viditelné oblasti byla změřena na dlani a dorzální straně levé a pravé ruky pomocí nízko šumového fotonásobiče. K studiu dynamiky této emise fotonu v průběhu 24 hodin, emise fotonu byla měřena v intervalech 2 hodin v 5 experimentech. Průměrná intenzita emise fotonu v rozsahu 24 hodin se lišila jak mezi subjekty, tak i mezi měřenými lokacemi. Fluktuace inetzity emise fotonu v průběhu 24 byly vyšší na dorzálních stranách rukou než na dlaních.
