The radiation environment in space is significantly stronger than on Earth, primarily due to galactic cosmic radiation (GCR) and solar radiation. This intense radiation poses serious risks to spacecraft, satellites and communication systems.

It continuously causes low-level damage to electronic circuits in satellites, degrades communication signals and presents a major threat to biological entities, including humans.

During solar events like solar flares and coronal mass ejections, the damage rate increases dramatically, potentially leading to the rapid failure of electronics, complete disruption of communication signals and GPS, and significant health risks to astronauts.

Our research

The program addresses the significant risks posed by space radiation to spacecraft, satellites, communication systems and biological entities. By developing innovative solutions and conducting cutting-edge research, the Space Radiation Effects Program aims to enhance the safety and reliability of space missions.

Led by Associate Professor Jeremy Brown and in collaboration with industry and government, this program is dedicated to advancing space radiation research and technology development, focusing on two primary streams.

Space radiation effects simulation, testing and qualification

This stream leverages Associate Professor Brown’s expertise in developing the Geant4 Monte Carlo radiation modelling toolkit, which is widely used by ESA, JAXA and NASA. The current focus is on assessing and mitigating space radiation risks for Australia’s Lunar Rover program as part of the ELO2 consortium.

Space radiation effects on biological systems

Building on Associate Professor Brown’s work in advanced radiation detection and dosimetry, this stream aims to understand how radiation impacts biological systems, including humans, bacteria and plants. The major focus is the BLANACE Radiobiology Program at the Holland Proton Therapy Centre, which develops advanced irradiation platforms for radiation physics and radiobiology research.

The Holland Proton Therapy Centre's R&D beamline generates large area proton fields for radiation physics and radiobiology studies.
