The saturation yield of the rhenium radioisotopes 186Re, 188Re, and 189Re on irradiation of a 186W target by the nuclei 4He, 3He, 1H, and 2H with energy 47, 25, 15.3, and 19 MeV, respectively, was measured by the activation method. The chosen energy of the accelerated particles made it possible to minimize the contribution of the activity of long-lived rhenium radioisotopes in the desired radionuclides. The highest yield 3240 ± 330 MBq/μA was obtained for the radioisotope 186Re in the reaction 186W(2H, 2n)186Re. The obtained yield makes it possible to plan on using in radioimmunotherapy the radionuclide 186Re produced by means of this reaction.

4He、3He、1H 和 2H 对 186W 靶辐照的 186Re、188Re、189Re 产量的测量

铼放射性同位素 186Re、188Re 和 189Re 分别用能量为 47、25、15.3 和 19 MeV 的原子核 4He、3He、1H 和 2H 照射 186W 靶时的饱和产率，通过活化法测量. 选定的加速粒子能量可以最大限度地减少所需放射性核素中长寿命铼放射性同位素的活性贡献。在反应 186W(2H, 2n)186Re 中，放射性同位素 186Re 的产率最高，为 3240 ± 330 MBq/μA。获得的产量使得可以计划在放射免疫疗法中使用通过该反应产生的放射性核素 186Re。
