96gTc As an Alternative Gamma-Ray Emitter for Medical Diagnostics

Resumo

The possibility of employing the isotope ^96gTc as a gamma-ray emitter in medical diagnostics is examined. Corresponding calculations by the TALYS-1.9 revealed that an irradiation of a ⁹⁶Mo target with protons of energy E =12 → 6 MeV at a current of 100 μA for six (eight) hours makes it possible to produce 20 (26) GBq of the isotope ^96gTc. In detecting gamma rays of energy in the range between 770 and 850 keV, the intensity of gamma rays from ^96gTc is close to their intensity for ^99mTc obtained in the reaction ¹⁰⁰Mo(p, n), so that one can use^96gTc as an alternative gamma-ray emitter.
