Figure 6: Results of ultra-weak photon emission measurements after mixing 0.5 ml of 10 mM tert-Butyl hydroperoxide with 1 ml of deionized water. The duration of measurement is 3 min. The vertical axis represents the number of photons per second and the horizontal axis represents seconds elapsed. (a) Deionized water. The number of photon emissions increased compared to day 1 (d1, d2, d3, and d4 indicate the day of measurement, resp.). (b) Deionized water treated in the noncontact manner. The number of photon emissions decreased drastically at day 4 (q1, q2, q3, and q4 indicate the day of measurement, resp.).
