摘要
-审查了在医疗诊断中使用同位素96 g Tc作为伽马射线发射器的可能性。TALYS-1.9的计算结果表明，用能量为E = 12→6 MeV的质子以100 μ a的电流照射96 Мо靶体6(8)小时，可以产生20 (26)GBq的96 g Tc同位素。在探测770和850 keV之间能量范围内的伽马射线时，96 g Tc的伽马射线强度接近它们在反应100 Мо(p, n)中获得的99 m Tc的强度，因此可以使用96 g Tc作为替代的伽马射线发射器。
— 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 Мо 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 Tс obtained in the reaction 100 Мо( p, n ), so that one can use 96 g Tc as an alternative gamma-ray emitter.
