Abstract

The widespread, if not general phenomenon of “ultraweak” photon emission from living cells and organisms, which is different from bioluminescence1), has been extensively 2–4) reviewed The measurements are carried out with a photomultiplier of high sensitivity in the range between 200 and 800 nm. The living material is kept within cuvettes in a dark chamber in front of the photomultiplier (for a more detailed description see refs.3–5)). With our equipment a photon current density of 1 photon/s/cm2 can be detected at a significance level of 99.9% within 10 hours. The uptake of count numbers within given time intervals and calculations are carried out with an interfaced computer.
