Accelerator mass spectrometry group
Radionuclides such as 236U and 239Pu were introduced into the environment by the atmospheric nuclear weapon tests and an be readily measured by accelerator mass spectrometry.

This project investigates contamination effects in negative ion sources used for accelerator mass spectrometry particularly relevant for the measurement of ultra-trace amounts of the long-lived radionuclides Chlorine-36 and Iodine-129 in environmental samples.

Radionuclides can serve as tracers and chronometers for environmental processes. The time scale for these clocks is set by the half-life of the respective radioisotope. Using accelerator mass spectrometry and decay counting this project aims investigate the chronology of the Early Solar System.
