Abstract: A radioactive multitracer solution of the 24 elements, e.g. Be, Na, K, Rb, Mg, Ca, Sr, Ga, As, Sc, V, Cr, Mn, Co, Fe, Zn, Y, Zr, Mo, Nb, Tc, Ru, Ag and In, was obtained from the nuclear reaction of 25 MeV/u 40Ar+Se with a series of chemical process. The multitracer solution was orally administered to normal and muscular tumourbearing mice of male Balb/c mice. Urine and faeces samples of mice were collected. The two group mice were sacrificed after 96 h. The uptake of 17 elements, Na, Rb, Ga, As, Sc, V, Cr, Mn, Co, Fe, Zn, Y, Zr, Tc, Ru, Ag and In, were simultaneously detected in normal mice while 15 elements, Na, Rb, Ga, Sc, V, Cr, Mn, Co, Fe, Y, Zr, Tc, Ru, Ag and In, were simultaneously detected in tumourbearing mice. Our results indicate that the majority of the detected elements were distributed in liver, kidney, pelt, tumour while a small fraction of the biotrace elements were distributed in heart and spleen (tumourbearing mice) in the two groups of mice. The higher concentrations of Fe, Na, Mn were detected in heart or kidney of normal mice. Na, Mn, Fe and Co showed better absorption in most tissues in the normal mice, except for Na and Mn in heart.
