Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements ....Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements, his project aims to determine the number of Auger electrons per nuclear decay accurately for medical isotopes. The outcome will be accurate dose data for radioisotopes, plus essential knowledge to develop new cancer treatments based on Auger electrons, which target a fraction of a cell.Read moreRead less
Nanoparticle radiosensitisation. This project aims to develop new knowledge through a better understanding of physics interactions of particles in compounds with sub-micron size. Research on radiosensitisation by sub-micrometre sized nanoparticles (NPs) is hot worldwide because it could treat cancer, but the physical/physico-chemical/biological mechanism of radiosensitisation is unclear because no physical models describe particle interactions at nanometre scale in solid state nanometre sized ob ....Nanoparticle radiosensitisation. This project aims to develop new knowledge through a better understanding of physics interactions of particles in compounds with sub-micron size. Research on radiosensitisation by sub-micrometre sized nanoparticles (NPs) is hot worldwide because it could treat cancer, but the physical/physico-chemical/biological mechanism of radiosensitisation is unclear because no physical models describe particle interactions at nanometre scale in solid state nanometre sized objects. This project will develop and evaluate specialised physics models to describe particle interactions in NPs and help optimise nanoparticle technology. It will develop expertise in Australia in physics modelling for nanomedicine and other applications of nanotechnology exposed to radiation (e.g. telecommunications, aviation and space).Read moreRead less
Radiation detectors to better understand ion interactions. This project aims to build a Heavy Ion Therapy Research and Treatment Centre in Australia. Understanding how ions interact with matter and their radiobiological effectiveness (RBE) is important. The project will introduce an Australian detector technology platform to research ion interaction physics and their RBE. It will develop radiation detectors for ion measurement with a wide energy range, including a practical RBE quality assurance ....Radiation detectors to better understand ion interactions. This project aims to build a Heavy Ion Therapy Research and Treatment Centre in Australia. Understanding how ions interact with matter and their radiobiological effectiveness (RBE) is important. The project will introduce an Australian detector technology platform to research ion interaction physics and their RBE. It will develop radiation detectors for ion measurement with a wide energy range, including a practical RBE quality assurance tool with submillimetre spatial resolution. The proposed Australian radiation detection technology is expected to improve understanding of the scientific mechanisms underpinning the radiobiological effectiveness of heavy ion radiation.Read moreRead less
Positrons in biosystems. This project aims to improve our understanding of the damage processes in Positron Emission Tomography (PET). PET is a widely used medical imaging technique, but there are gaps in our understanding of the underlying interactions, in particular in the case of the radiation damage induced during the process. By using new models incorporating accurate descriptions of interactions processes, verified by experimental measurement, this project will develop a new model of posit ....Positrons in biosystems. This project aims to improve our understanding of the damage processes in Positron Emission Tomography (PET). PET is a widely used medical imaging technique, but there are gaps in our understanding of the underlying interactions, in particular in the case of the radiation damage induced during the process. By using new models incorporating accurate descriptions of interactions processes, verified by experimental measurement, this project will develop a new model of positron transport in PET. The project will allow validation of predictions from the model by undertaking experiments in liquid water.Read moreRead less
