1182. A life of a physicist in the radiochemical laboratory

Jerzy-Wojciech Mietelski (The Henryk Niewodniczanski Institute of Nuclear Physics, Polish Academy of Sciences (IFJ PAN))

5/10/26, 6:45 PM

Radionuclides in the Environment, Radioecology

Plenary

As it happens that way, that I am a this year Hevesy Medal awarded I would like to tell some words on my experience. I am a physicist, who was graduated in neutrino physics in 1984, but the life paths throwed me into environmental radioactivity and radiochemistry. I deserve my scientific career to Chernobyl accident. I started work for the Institute of Nuclear Physics from gamma spectrometry...

1138. Positioning Sg, Bh. Hs and Cn into the Periodic Table – a historic review

Prof. Heinz Gäggeler (Paul Scherrer Institut)

5/11/26, 8:30 AM

Chemistry of Actinide and Trans-actinide Elements

Plenary

The development of fast on-line chemistry techniques – coupled to on-line detection systems - allowed to push the limit of chemical knowledge into the range of the Perioidc Table where isotopes of elements have half-lives in the second range only. With the On-Line Gas chemistry Apparatus OLGA (using isothermal gas chromatography) the chemical identification of Seaborgium, Sg [1] and Bohrium, ...

1157. Applications of cutting-edge mass spectrometry in multidisciplinary environmental studies

Prof. Jixin Qiao (Technical University of Denmark)

5/11/26, 9:00 AM

Radioanalytical Methods

Plenary

Efficient and accurate analysis of radionuclides is critically important across a wide range of fields, including environmental and food radioactivity monitoring, decommissioning of nuclear facilities and waste management, nuclear forensics, geochronology, earth science and environmental tracer studies. While most γ-emitting radionuclides can be measured directly after simple sample...

1235. Radiochemical Separation for the Recovery of 244Pu from Legacy Mark 18A Targets

Kenneth Czerwinski (University of Nevada, Las Vegas)

5/11/26, 9:30 AM

Production and Application of Radionuclides

Plenary

The recovery of long lived transneptunium isotopes from legacy reactor irradiated materials represents a critical intersection of radiochemistry, national resource stewardship, and nuclear talent development. The Mark 18A targets, produced and irradiated at the Savannah River Site during the 1960s through the 1980s, contained kilogram quantities of ${}^{242}\mathrm{Pu}$ that were exposed to...

1385. The role of actinide separation chemistry in sustainable nuclear fuel cycles

Robin Taylor (The University of Manchester)

5/11/26, 10:30 AM

Separation Methods, Speciation

Plenary

Nuclear energy is a secure, low carbon source of energy. After irradiation in the reactor, most countries store the used (or spent) nuclear fuels ready for geological disposal (the 'open' or 'once through' fuel cycle). However, the overall sustainability of nuclear energy can be enhanced by moving towards 'closed' fuel cycles based on the recycling of various components of used fuels. A key...

1266. A Single-Center Heidelberg Experience: Molecular Biomarkers Beyond PSA for Risk Stratification in Combined Targeted Radioligand Therapy

Martina Benešová-Schäfer

5/11/26, 11:00 AM

Radiopharmaceutical Chemistry, Labelled Compounds

Plenary

Targeted radioligand therapy (TRT) directed against prostate-specific membrane antigen (PSMA) represents a promising strategy for metastatic castration-resistant prostate cancer (mCRPC). However, reliable treatment prediction and therapeutic resistance limits durable clinical benefit.
We describe a prospective single-center experience from Heidelberg encompassing ~100 mCRPC patients treated...

1133. Corrosion of nuclear waste glasses in long term tests

Dr Michael Ojovan (Wuhan University of Technology)

5/11/26, 11:30 AM

Chemistry of Nuclear Fuel Cycle, Radiochemical Aspects of Nuclear Waste Management

Plenary

Alkali borosilicate glasses were internationally selected as basic immobilizing matrices for high level nuclear waste aiming to retain toxic components for timeframes exceeding millennia. Corrosion of glasses is a complex process evolving with time which is mainly dependent on glass composition and environmental conditions. Laboratory tests of nuclear waste forms are mandatory as a part of...
