    How seismology helps the world detect nuclear weapons tests (amongst other things), with Professor Hrvoje Tkalčić

    Imagine a global network of sensor stations, ready to detect even the smallest nuclear weapons test. This network is in fact a reality. As we learned in our last episode, the Comprehensive Nuclear Test Ban Treaty Organisation’s monitoring network is up, running, and ready for the Treaty to enter into force. One of the most important of those stations is located in Australia's remote Northern Territory – the Warramunga Seismic and Infrasound Facility – and it's directed by Professor Hrvoje Tkalčić, Head of Geophysics at the Australian National University. In this episode, Professor Tkalčić joins our host, A/Prof Liz Williams, to talk about what seismology actually is – how waves generated by earthquakes, storms, and even whale calls can be used to see inside the earth – and how the extraordinary silence of the Australian outback makes it one of the best places on the planet to listen for nuclear tests. Professor Tkalčić is also the author of a brand-new popular science book called, When Worlds Quake: The Quest to Understand the Interior of Earth and Beyond, which has just been released in the English language by Princeton University Press [link to publisher page here].

    Nuclear Testing in a No-Test World: Verification, Politics, and Risk – with Prof Trevor Findlay

    When President Trump announced last year that the US might resume nuclear weapons testing, it raised a question the world hasn't had to seriously consider in decades: what happens if they do? In this episode, Liz Williams sits down with Professor Trevor Findlay, a nuclear governance expert who was involved in the early diplomatic work that became the Comprehensive Nuclear Test Ban Treaty (CTBT). The CTBT exists, the monitoring network is nearly complete, and the organisation behind it is operating, but the treaty never entered into force. What would states would actually do if testing resumes? In this conversation, Trevor shares insights into how the treaty and accompanying verification system was built, why it was designed the way it was, and what it all means now that nuclear testing is once again in the news. CREDITS Guest: Professor Trevor Findlay is an honorary professor at the University of Melbourne with expertise in nuclear governance. He has spent many years working on the issue of nuclear testing and the Comprehensive Nuclear Test Ban Treaty and its verification system. Host: A/Prof Liz Williams is the Interim Director of the ANU Nuclear Stewardship Network and Nuclear Systems Discipline Lead for the ANU School of Engineering. Audio producer: Martin Franklin (East Coast Studio) A note of correction: When posting this episode, Liz - who typically struggles with remembering names on a good day - realized she dropped 'Nuclear' from Comprehensive Nuclear Test Ban Treaty consistently. This is incorrect. When stating the full treaty or organisation name, one should include the 'nuclear', just as Trevor does consistently throughout the episode. We'll work on correcting the audio, but for now, just remember the treaty / organisation acronym drops the N, but the full name does not.

    What are theranostics, and how are they used to treat cancer? With Dr Ashleigh Hull and Dr Stephen Tronchin

    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. Credits Guests: Ashleigh Hull, Stephen Tronchin Host: Elizabeth Williams Audio Producer: Martin Franklin (East Coast Studio) Show notes Stephen wanted to clarify that beta particles have a range of 1-10 mm in tissue.

    Citizen science and nuclear technologies, with A/Prof Michiel Van Oudheusden

    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. CREDITS Guest: Michiel Van Oudheusden Host: Liz Williams Audio Producer: Martin Franklin (East Coast Studio) Acknowledgements Thank you to A/Prof Fabien Medvecky for recommending Michiel's work to me.

    Exploring nuclear safeguards cultures, with Prof Trevor Findlay

    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.

    How does plutonium behave in marine environments? - with Madison Williams-Hoffman

    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. Credits Guest: Madison Williams-Hoffman Host: Liz Williams Audio producer: Martin Franklin (East Coast Studio) Contacts If you are interested in projects and wish to contact Maddy about collaborating or joining the group as a student, you can reach her via the email on this webpage.

    Trust, technology, and radioactive waste, with Nate Smith

    What do you think about radioactive waste? This is a question that most nuclear professionals need to consider at some point in their careers. In today’s episode, Tellus CEO and Managing Director Nate Smith joins us to talk about what it’s like to establish a radioactive waste facility in Australia. We learn about what radioactive waste is, the many industrial processes –including clean energy technologies –that produce it, and some of the ways this waste is managed. Nate also shares insights into consent-based siting, community engagement with Traditional Owners, and the importance of building trust.
