Matrix effects on Kβ/Kα X-ray intensity ratios of technetium-molybdenum systems

The K/K X-ray intensity ratios of^99mTc produced in molybdenum compounds by the /n,/^– processes were found different from those of chemically separated^99mTc. Chemical states of molybdenum seem to have an effect on the X-ray ratio K ₂ /K. The X-ray intensity ratios were investigated with other technetium nuclides^95mTc and^97mTc. The Mo X-rays and Tc X-rays emitted from these nuclides in molybdenum matrix showed smaller values of K ₁ /K and K ₂ /K than those for chemically separated ones. Influence of electronic structure on the ratios by surrounding matrix was discussed.
