| Abstract: | Eleven elements, I, Br, Mg, Mn, Cu, Na, V, Cl, Al, Ca and S, have been determined in human hairs by reactor NAA with short irradiations. Multielement characteristics of Chinese human hairs have been studied in cumulative frequency distribution, correlation and in relation to sex and age. The results have been used for forensic studies by introducing double criteria-"difference rate" and "probability of accidental coincidence".Experimental results are summarized in 7 tables, and briefly discussed. |

| Keywords: | cumulative frequency distribution correlation coefficient difference rate accidental coincidence probability identity discrimination confidence level |
