isotopproduktion

Isotopproduktion refers to the production of isotopes, including radioisotopes, for scientific, medical, and industrial use. Isotopes are variants of elements with different numbers of neutrons. Production is achieved by nuclear reactions that introduce neutrons or alter nuclear charge in a target material, followed by chemical separation to isolate the desired isotope.

In practice, isotopes are produced in nuclear reactors or particle accelerators. In reactors, targets are irradiated with neutrons, enabling neutron capture or fission to create new isotopes. Examples include molybdenum-99, produced in reactors and decaying to technetium-99m for medical imaging. In accelerators, charged particles such as protons or deuterons strike targets, yielding radionuclides such as fluorine-18, used for PET, or gallium-68. Spallation and fragmentation are also used for producing exotic isotopes in large accelerator facilities. After irradiation, chemical separation and purification retrieve the desired isotope and, for medical use, meet purity and dose specifications.

Common radioisotopes include Tc-99m, I-131, Co-60, Ga-68, F-18, C-11, N-13, and O-15, used in diagnostics, therapy, or tracing studies. Stable isotopes are employed in geology, archaeology, environmental studies, and materials science.

Safety and regulation govern isotop production due to radiation exposure and radioactive waste. Facilities are licensed, and production quality is ensured by standards and supplier accreditation. The field has evolved toward accelerator-based production to supplement aging reactor inventories and improve supply reliability.
