Reactor Operation, Kjeller
The utilization of the reactor includes research activities as neutron physics, activation analysis, neutronradiography etc. Neutron irradiation in the JEEP II reactor is used to create radioactive materials for use in the production of radiopharmaceuticals and radiochemicals. Radioactive tracers are also produced, along with radiation sources for use in industry and research.
Neutrons are also used for neutron transmutation doping of silicon crystals for production of semiconductor materials. Neutron irradiation of superpure silicon crystals generates in the crystals an evenly distributed content of phosphorous atoms, thereby producing the desired semiconductor properties. IFE's activity in this area covers about 10% of the world marked for such products.
The Institute's gamma irradiation plant is based on ionizing radiation from a radioactive cobalt (60Co) source. The radiation is mainly used to reduce the bacterial content of various products, and to sterilize disposable medical equipment and other materials. The most important product group at present comprises spices and other flavourings for the foodstuffs industry.
