Forget needles in haystacks: if you’re looking for a million billionth of a gram of a radioactive isotope, hidden, say in sea water, coral, or the antler of a deer – then accelerator mass spectrometry is the tool for you! In this episode of Megavolts Dr Michaela Froehlich tells us all the weird...

In the latest episode of MegaVolts we talk about fusion and when it fails. It’s a grey area – sometimes colliding nuclei miss, sometimes they bounce and sometimes they stick for a little while, dance around each other and then go their separate ways, both somehow changed forever… Getting...

What do asteroid strikes, ancient glaciers and landslides have in common? They can all be studied at the Heavy ion Accelerator Facility (HIAF) using Accelerator Mass Spectrometry (AMS). In this episode of MegaVolts, UNSW Professor Tim Barrows – an earth scientist – shares his work using...

The challenge with detecting dark matter is that the signal will probably be incredibly small – perhaps only a couple of particles per day. So it would be really easy to be fooled by some other signal, such as lead-210, which is radioactive. Dr Anton Wallner is testing the crystals that will be used...
