Small amounts of Ga, Yb, and Tl were injected into rats implanted with several kinds of tumor. Samples of liver, serum, brain and tumor, taken out from these rats, were bombarded by 3.5 MeV protons and the induced X-rays were analysed using a Si(Li) detector. Absolute concentrations of these elements taken up by these tissues were determined referring to a known concentration of doped uranium. Some concentration of elements and species of tumor are found.
