Ionizing radiations transformed into music.These radiations are emitted by naturally occurring isotopes such as C-14 in Human Body. Whey these isotopes decay to attain stable nuclear configurations they emit Xrays, Alpa/Beta particles or even gama rays. The frequency of this type of ionizing radiation when scaled down to audible range can be transformed into music. The periodicity can be transformed into tones and you have an song being performed by a bunch of them.
Checkout the Radioactive Orchestra online by selecting your favorite isotopes you can make your own song.
