THE MEASUREMENT OF ULTRAWEAK LUMINESCENCE EMSSION FROM HUMAN BODY SURFACE
|
Abstract:
A single photon counter, which can measure ultrawesk luminescence under room temperature with very low dark counts, has ha developed and used in the study ofultruaweak luminescence emission from the sauface of human body. It was found that theluminescence intensities of surface at different pads of human body are quite different anddecreasing in following order: fingers the strongest, palms the second, then forehed, cheeks,fore arms, upper arms and chest and abdomen survively. It is also noticed that illuminationgreatly influence the luminescence of the htman body surface. Different parts of bodyhave different magnification of luminescence and different decay rate afters exposeal to sunlight. The luminescence intensity of surface increases along with the increase of surfacetmpereature. When body surface is coatad with some juice its luminescence inthesitychanges obviously.
