| Popis: | The study provides an alternative method of producing the medically interesting 89Zr isotope by using 55 MeV bremsstrahlung irradiation of natural niobium and natural molybdenum samples. The yields of the natNb((γ,4n)+(γ,p3n))89Nb−89Zr, 92Mo((γ,3n)+(γ,p2n))89Nb−89Zr and 94Mo(γ,αn) 89Zr reactions were obtained as a result of the research. It was estimated that after irradiation of 1 g of natural niobium target with a current of 1 μA for the duration of 1 h 300 kBq of 89Zr was formed. |
