Nuclear Matters

<p>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.</p><p>Dr Ashleigh Hull is a nuclear medicine technologist and lecturer in medical physics, and Dr Stephen Tronchin is a post-doctoral research fellow.

<p>What roles can citizen science play in the governance of nuclear technologies? In this episode, I explore this topic with <a target="_blank" rel="noopener noreferrer nofollow" href="https://research.vu.nl/en/persons/michiel-van-oudheusden/">Michiel Van Oudheusden</a>, 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.</p><p>This is our final episode for this season. Stay tuned for Season 2 in March 2026. </p><p><strong>CREDITS</strong></p><p>Guest: Michiel Van Oudheusden</p><p>Host: Liz Williams</p><p>Audio Producer: Martin Franklin (<a target="_blank" rel="noopener noreferrer nofollow" href="https://eastcoaststudio.com.au">East Coast Studio</a>)</p><p><strong>Acknowledgements</strong></p><p>Thank you to <a target="_blank" rel="noopener noreferrer nofollow" href="https://cpas.anu.edu.au/people/associate-professor-fabien-medvecky">A/Prof Fabien Medvecky</a> for recommending Michiel's work to me.</p><p><strong>The usual end matter</strong></p><p>Nuclear Matters is a production of the Australian National University College of Systems and Society.

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. </p><p><strong>Credits</strong></p><p>Guest: Trevor Findlay</p><p>Host: Liz Williams</p><p>Audio producer: Martin Franklin (<a target="_blank" rel="noopener noreferrer nofollow" href="https://eastcoaststudio.com.au">East Coast Studio</a>)</p><p><strong>Acknowledgements</strong></p><p>Thank you to Dr Russell Leslie for recommending Trevor's book to me. </p><p><strong>The usual end matter</strong></p><p>Nuclear Matters is a production of the Australian National University College of Systems and Society.
