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.

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.
