摘要
研制了一种能在室温下正常工作的高灵敏度并具有极低暗计数的光子计数器。用它来研究人体体表超弱光的发射。测量结果表明：人体不同部位体表发光强度是很不一致的：手指发光最强、掌心次之、然后是面颊、前额、小臂、上臂、胸腹部等依次减弱。先照对体表的发光有很大影响。体表不同部位因光照引起发光强度的增加值差异很大；避光后先强的衰减速度也不同。体表的发光强度随体表温度的升高而增强。某些物质接触体表可以使体表发光强度发生很大变化。
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.
