The multitracer technique was applied to the simultaneous evaluation of the behavior of a large number of radioactive nuclides.
The binding affinity of various trace elements with blood components and the pH-dependence of binding affinity of the elements
with serum proteins were examined using the multitracer technique. Each element showed characteristic binding to each blood
component and serum protein. The results are discussed in terms of chelating ability of metal ions and the nature of the serum
