Activation Analysis of Human Head Hair. III. : Activation Analysis of Hair by Short Time Irradiation

Abstract

Hair samples were analysed by the short time irradiation with neutrons using pneumatic tube for the purpose of increasing detectable elements and establishing a rapid method of analysis in a practical case. Spectra of short-life nuclides of hair samples from different donors were sufficiently characteristic and distinguished from each other. Main detectable elements were Al, Br, Cl, Mn, and Na, and sometimes I, Se, Ti, and Zn were detected. Determination of Al and Cl was possible by a short irradiation. Their complex spectra could be analysed by the stripping method. As polyethylene sheet contains a markedly large quantity of Ar and other elements which disturb the determination of components in samples, its use in the non-destructive activation analysis must be reconsidered.
