The Radioactive Orchestra 2.0 uses energy from the decay of low energy isotopes to make music. The energy that is released, according to Fox News, is read by a gamma spectrometer. If the sample – which could be a radioactive material such as uranium — is moved closer and farther away from the device, a pulsating rhythm is created.
The story has links to videos that explain what is going on and provide samples of the music. Swedish musician Kristofer Hagbard is quoted on the rationale for the project: “’The goal is not to create the ultimate sonification of radiation, but to experiment with science as a starting point for making art.”
