The safety case of a deep geological repository (DGR) for long-term nuclear waste storage requires extensive knowledge about the interactions of the radioactive inventory with the (geo-)technical and geological barriers. Due to their long half-life, high radiotoxicity and complex aqueous chemistry, plutonium isotopes are of major interest as high-level radioactive waste (HLW) that needs to be...

The Ural Mountains are a very interesting region for climate research on Earth. This mountain range runs north-south more than 2500 km from the Arctic Ocean to the Eurasian Steppe belt. Being the conventional boundary between Europe and Asia, the Urals are also the endpoint of climatic effects, caused by the Atlantic or Siberian air masses. Since Ancient times the region is world-known for its...

Micron sized fragments of nuclear fuel, so called “hot particles” have been released during the Chornobyl nuclear accident in 1986 into the exclusion zone (CEZ). The combination of flotation with high-density-solutions, electron microscopy and a micromanipulator allow the isolation of single hot particles from soil samples of the CEZ [1]. Non-destructive mass spectrometry is performed on...
