Abstract

As human space exploration expands towards the Moon, Mars and beyond, protecting astronauts from the health risks associated with space radiation remains a critical challenge.

This presentation will provide an overview of the space radiation environment, sources of human radiation exposure, applicable dose limits and the associated short- and long-term health risks. It will explore the challenges of assessing and managing radiation exposure in space, highlighting the importance of radiation protection strategies to support safe and sustainable human exploration.

The presentation will also showcase how ANSTO contributes to research on the biological effects of radiation and supports the development of radiation protection approaches and countermeasures to mitigate risks to astronauts on future space missions.
