Method of producing radionuclides

The invention relates to a method of producing radionuclides. According to the method, a target medium comprising at least a target nuclide material is irradiated in an irradiation zone with neutron irradiation. Radionuclides form in the target nuclide material as a result of the irradiation, and at least some of the formed radionuclides are ejected from the target nuclide material. The ejected radionuclides are then captured and collected in a carbon-based recoil capture material which does not have an empty cage structure at crystallographic level.Delft University of Technolog

Preparation of 31Si-labelled silicate: A radiotracer for silicon studies in biosystems

No-carrier added 31Si was produced by 31P(n,p)31Si in the nuclear reactor of the Delft University of Technology. Several methods were investigated to remove the side product 32P, and the chemical form of 31Si was investigated. All methods except one gave good results. Anion exchange with Dowex resin gave the best results in activity concentration (3.8 ? 106 Bq/ml, with only 3.2 ? 103 Bq/ml 32P as by product) and specific activity (As > 17 TBq/g). The product is suitable for biological systems.Radiation, Radionuclides & Reactors / Radiation and Isotopes in HealthApplied Science
