Peter Steier

Peter Steier is an Associate Professor at the Faculty of Physics, University of Vienna, specializing in Isotope Physics. With over 260 publications and 70 academic activities since 1997, his research focuses on Accelerator Mass Spectrometry (AMS) applications in environmental science, nuclear forensics, and geochemistry.

• Key Affiliation: Vienna Environmental Research Accelerator (VERA)
• Projects: Lead coordinator of the 2019–2022 EU-funded RADIATE project for ion beam technology development.

His work encompasses:

• Environmental tracing of uranium isotopes (236U, 233U) to identify nuclear reprocessing impacts in marine systems like the Baltic Sea and Arctic Ocean.
• Advancements in Ion-Laser Interaction Mass Spectrometry (ILIAMS) for isobar suppression and ultra-trace detection of radionuclides such as 90Sr and 135Cs.
• Chronological studies in archaeology (e.g., radiocarbon dating of Hala Sultan Tekke) and geology (e.g., dating small impact craters in Sweden).

Recent publications highlight his expertise in:

• AMS methodology for actinide analysis and quality control.
• Diffusion studies of uranium and americium in clay systems for radioactive waste management.
• Using cosmogenic nuclides (e.g., 10Be, 26Al) in geological dating and erosion studies.
