96 g Tc As an Alternative Gamma-Ray Emitter for Medical Diagnostics

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