LRC - Laboratory of Radiochemistry

The Laboratory of Radiochemistry (LRC) focuses on fundamental research and on education in the field of radiochemistry. The topics studied within LRC cover a wide and diverse range of radiochemical research, including studies on the chemistry of heavy elements, harvesting exotic radionuclides from irradiated accelerator components for use in fundamental research, development of innovative radiopharmaceuticals and studying the chemical behaviour of radionuclides in liquid metals proposed as target material or coolant in future nuclear facilities.

Cancer medicine using PSI’s neutron source

Human Health Research Using Neutrons

At the neutron source SINQ, PSI researchers are producing special radionuclides that aid in the development of new and more effectively targeted cancer therapies. In this they collaborate closely with the clinics in the surrounding area.

Material from PSI helps to check inconsistencies in the Big Bang theory

Media Releases Research Using Neutrons Matter and Material Particle physics

Shortly after the Big Bang, radioactive Beryllium-7 atoms were formed, which today, throughout the universe, they have long since decayed. A sample of beryllium-7 artificially produced at PSI has now helped researchers to better understand the first minutes of the universe.

Nuclear data for nuclear installations: Radiochemistry improves the precision of the cross-section data of long-lived radionuclides

Knowledge about the cross sections data of the target materials used for spallation neutron facilities (SNF) and accelerator driven systems (ADS) is essential for the licensing, safe operation and decommissioning of these facilities. In addition, these data are important to evaluate and improve the existing computer simulation codes. Especially the α-emitter 148Gd has a large contribution to radio-toxicity of spallation target facilities with its 74.6 years of half-life.

Radioactive targets produced at PSI enable improving the Big Bang Theory

One of the long-lasting unsolved problems in Nuclear Astrophysics is the so-called "Cosmological Li Problem", i.e. the large discrepancy between the primordial 7Li abundance predicted by models of Big Bang Nucleosynthesis and the one inferred from astronomical observation. The study of the production/destruction rates of the radioactive precursor 7Be is one of the clues for solving this problem.

Post Irradiation Examination of MEGAPIE – How radiochemical analytics helps looking inside a high-power liquid metal spallation target

PSI radiochemists now finished the radiochemical analysis of the residue nuclei production in the Lead-Bismuth Eutectic (LBE) of the MEGAPIE target. Twenty – mostly safety-relevant – radionuclides could be identified and quantified. Comparisons with theoretical predictions show acceptable agreement in most cases, but also considerable discrepancies for some selected radionuclides. Moreover, the scientists learned that noble elements like Gold, Silver, Mercury or Rhodium are homogeneously distributed in the bulk LBE, while others, sensitive to reduction/oxidation (Lanthanides, Iodine, Chlorine), tend to accumulate at exposed positions like vessel walls and free surfaces. These results will help to improve models and codes for predictions and, thus, will improve the safety of existing and future facilities.

Designer nuclide for medical applications

Medical Science Human Health Radiopharmacy

Researchers at the PSI have for the first time used a cyclotron to produce the radionuclide scandium-44 in a quantity and concentration as needed for medical treatment. With that, they have achieved the first precondition for scandium-44 to be used one day for medical tests in hospitals.

One atom at a time

Matter and Material

At the PSI, the Heavy Elements Research Group explores the exotic, unstable atoms at the end of the periodic table of elements. The dream: to discover one day the island of stability that could exist beyond the elements charted so far on the chemists' map.
