Strontium-90 in the environment

Strontium is a naturally occurring element that accumulates in bones, with its radioactive isotope Sr-90 posing environmental concerns due its presence in nature.

Paving the way to study the chronology of the early solar system

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.

Radioimpurities in particle detectors for dark matter studies

This experiment will characterise dark matter detector material. Lowest levels of natural radioactivity in high purity samples will be analysed via ultra-senstive single atom counting using acclerator mass spectrometry.

Single atom counting for stellar nuclear synthesis studies

In this project accelerator mass spectrometry at the 14-million volt accelerator at ANU is used to determine nuclear reaction probabilities relevant for astrophysics.
