Nuclear Matters

In this episode, Dr Ashleigh Hull and Dr Stephen Tronchin join host Liz Williams to explore theranostics — a cutting-edge approach to cancer treatment that uses radiopharmaceuticals to both detect and treat cancers from within the body. They cover the science behind how these treatments are designed to target cancer cells, which cancers theranostics is already being used for, and the real-world supply chain challenges that determine how many patients can access these therapies. The episode closes with a look at what's on the horizon for the field in Australia and globally.
Dr Ashleigh Hull is a nuclear medicine technologist and lecturer in medical physics, and Dr Stephen Tronchin is a post-doctoral research fellow. Both work at Adelaide University and are part of Radinnovate, an Australian Research Council Industrial Transformation Training Center focused on developing the next generation of nuclear and radiation science researchers for Australia.

We thought we'd share a sneak peek of the new season of Nuclear Matters. The first full episode is coming at the end of April. If you haven't already subscribed to the feed, what are you waiting for? The Apple Podcasts link is here if that's where you prefer to find us (and while you're at it, please leave us a review or some feedback - it helps us keep this going!).
While you wait, you can keep up with Australian National University's work on all things nuclear by following the ANU Nuclear Stewardship Network on LinkedIn.
Thanks to Martin Franklin from East Coast Studio for the audio production of this teaser.

What roles can citizen science play in the governance of nuclear technologies? In this episode, I explore this topic with Michiel Van Oudheusden, Associate Professor of Public Participation in Science and Democracy at VU Amsterdam. Michiel previously worked at the Nuclear Research Centre in Belgium, and had the opportunity to study citizen science initiatives focused on managing nuclear technologies in both Japan and the European Union. We explore what he found in this work, and discuss how these lessons might apply to the Australian context – particularly given the growth in our involvement with nuclear technology due to AUKUS.
This is our final episode for this season. Stay tuned for Season 2 in March 2026.

In this episode, we’re joined by Professor Trevor Findlay, honorary professorial fellow at the University of Melbourne and author of Transforming Nuclear Safeguards Culture: The IAEA, Iraq, and the Future of Non-proliferation.
With the world’s growing interest in nuclear technologies—especially in the context of AUKUS and the global push for clean energy—understanding how nuclear safeguards work to support non-proliferation is crucial. But beyond the technicalities lies a deeper, often overlooked dimension: culture. What assumptions shape the way nuclear inspectors operate? How do values, habits, and institutional norms influence the effectiveness of global non-proliferation efforts? We'll explore these questions (and more) in the episode, so listen in.

This episode of Nuclear Matters takes us to Montebello Island, a former UK nuclear weapons test site off the coast of Western Australia. Our guest is Madison Williams-Hoffman – or Maddy, for short. Maddy is a postdoctoral fellow at the Radinnovate ARC Training Centre for Radiation Innovation at ANU. She uses chemistry to explore how plutonium from the weapons tests carried out in that region have moved through the marine environment.
She has kindly joined us to talk us through what she’s found, and help us understand why it matters for our explorations of future uses of nuclear technologies.

Errata
Maddy flagged that the Plutonium ratio they usually look at is 240Pu/239Pu, rather than 239Pu/240Pu.
