Abstract

The Kβ/Kα X-ray intensity ratios of99mTc produced in molybdenum compounds by the /n,γ/β processes were found different from those of chemically separated99mTc. Chemical states of molybdenum seem to have an effect on the X-ray ratio K β2 /Kα. The X-ray intensity ratios were investigated with other technetium nuclides95mTc and97mTc. The Mo X-rays and Tc X-rays emitted from these nuclides in molybdenum matrix showed smaller values of K β1 /Kα and K β2 /Kα than those for chemically separated ones. Influence of electronic structure on the ratios by surrounding matrix was discussed.
