Spallation Produced Radioisotopes for Nuclear Medical Application

Spallation Nuclear Data

Brief reviews are made of the theoretical models, the nuclear and nucleon data used in the simulation calculations of the nuclear spallation process. The spallation, as seen from the spallation neutron spectrum, can be described quite well as the successive three (1) intra-nuclear cascades, (2) particle emissions from the pre-equilibrium step process: state, (3) competing decay of the residual ...

Fission-residues Produced in the Spallation Reaction

Fission fragments from 1 A GeV U projectiles irradiating a hydrogen target were investigated by using the fragment separator FRS for magnetic selection of reaction products including ray-tracing and E-ToF techniques. The momentum spectra of identi ed fragments were analysed to provide isotopic production cross sections, ssion-fragment velocities and recoil momenta of the ssioning parent nuclei....

Radioisotopes produced by neutron irradiation of food.

The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only dominant under certain conditions. The com...

Dose Coefficients for Radionuclides Produced in a Spallation Neutron Source

Processing of generator-produced 68Ga for medical application.

UNLABELLED The (68)Ge/(68)Ga generator provides an excellent source of positron-emitting (68)Ga. However, newly available "ionic" (68)Ge/(68)Ga radionuclide generators are not necessarily optimized for the synthesis of (68)Ga-labeled radiopharmaceuticals. The eluates have rather large volumes, a high concentration of H(+) (pH of 1), a breakthrough of (68)Ge, increasing with time or frequency of...
