摘要：

Trace elemental analysis was carried out in the biological samples of normal. adenoma and carcinoma thyroids using particle induced X-ray emission technique (PIXE). A 2 MeV proton beam was employed to excite the samples. The elements Cl, K. Ca. Ti. V. Cr. Mn, Fe. Co. Ni. Cu. Zn, As, Sr, I. Hg and Pb were identified and their concentrations were estimated. The concentrations of the elements Ca, Cu. Zn, As, I and Hg are found to be much lower in carcinoma thyroid than those in the normal thyroid while the concentration of the elements K, Ti, V, Cr, Mn. Fe, Co and Sr in carcinoma thyroid are higher than the concentrations in normal thyroid. The lower and higher values of some of the elements in carcinoma thyroid may be attributed to some pathological factors. (C) 2002 Elsevier Science B.V. All rights reserved.
