Biophoton emission from fingernails and fingerprints of living human subjects.
Biophotons emitted from the center of fingernails and fingerprints from living humans are measured for twenty healthy subjects. We devised a dark box with a photo multiplier tube (H6180-01, Hamamatsu, Japan) whose spectral range is 300 nm to approximately 650 nm and a mount with a light-receiving hole of diameter 8 mm such that biophotons from the small circular area of nail or print of each finger are detected. Significantly more biophotons are emitted from fingernail than fingerprint for each finger of every subject. For thumb the average biophoton emission rate is 23.0 +/- 4.5 counts per second, and 17.2 +/- 2.0 counts per second from the nail, and print, respectively. There is a slight tendency that the little finger emits less than the other fingers. But some fingers emit far stronger than others, and it depends upon each individual subject which finger emits strongest.
