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.

Montebello Islands - A former nuclear test site

This project investigates anthropogenic radionuclides from the 1950s–60s nuclear tests in various marine sample types near the Montebello Islands. By analysing isotopic signatures, it aims to distinguish contributions from Montebello and Pacific Proving Ground tests, supporting environmental tracing, dose assessment, and collaboration with institutions like ANSTO and ARPANSA.

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.

Radioactivity in our environment

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.

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.
