LRC and BluAct explore innovative filter material

Fission products from the PSI-SINQ gas-jet facility, as operated by LRC, were used to reveal the separation of relevant radionuclides from radioactively contaminated water. The tests were conducted using a novel innovative filter material made of a blend of milk whey and active charcoal on cellulose. This material has been developed by the ETHZ spin-off BluAct Technologies GmbH.

The importance of this project was recently highlithed in ETSON/news

Weissbuch Radiochemie Schweiz

In December 2020, the Swiss Academy of Sciences (SCNAT) published its white book on radiochemical education in Switzerland. The report was authored under the lead of Prof. Dr. Roger Alberto (University of Zurich), Dr. Mario Burgener (Spiez Laboratory), and Prof. em. Dr. Heinz W. Gäggeler (University of Bern/Paul Scherrer Institute) and comprises contributions from many experts on the topic from various institutions throughout Switzerland. The white book highlights the imminent loss of experts in the field of radiochemistry and provides solutions to counteract this development.

Radiochemistry at ETH Zurich

As of December 10, 2020, the ETH Zurich appointed PSI’s Prof. Dr. Patrick Steinegger as assistant professor of radiochemistry  (tenure track). Thus, the ETH domain took first counter  measures against the imminent loss of radiochemical expertise  in Switzerland, emphasized in the “Weissbuch Radiochemie  Schweiz” by the Swiss Academy of Sciences (SCNAT).  Furthermore, the December issue of CHIMIA (Swiss Chemical  Society) invited to present the diverse radiochemical activities  throughout the country.

Young Scientist Prize 2020 of the Swiss Neutron Science Society

The Swiss Neutron Science Society as one of the representatives of the neutron scatterers in Switzerland honors each year young scientist in recognition of a notable scientific achievement in the form of a PhD thesis or to a nominee with an exceptional track record in neutron science.

In 2020 one of the prizes sponsored by SwissNeutronics was awarded to Jiri Ulrich (LRC/PSI) for his doctoral thesis on “High precision nuclear data of Mn-53 for astrophysics and geosciences”.

Communiqués de presse Physique des particules Fondements de la nature SINQ

Le Big Bang a été immédiatement suivi de l'apparition d'atomes de type béryllium 7. Dans tout l'univers, la plupart de ces atomes se sont désintégrés depuis belle lurette. Un échantillon de béryllium 7, produit artificiellement au PSI, vient d'aider les chercheurs à mieux comprendre les premières minutes de l'univers.

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.
