Raspberry Pi Pico Detects Gamma Rays in Open Spectroscopy Undertaking

Posted on

There are numerous helpful issues you are able to do with a Raspberry Pi Pico (opens in new tab), as our itemizing of the most effective Raspberry Pi Initiatives (opens in new tab) underlines. Nevertheless, right here’s one we admit we’d by no means considered: detecting radiation. Physicist Matthias Rosezky, AKA Nuclear Phoenix (opens in new tab), whose work has additionally been lined by Hackaday (opens in new tab), has written up an in depth account of constructing a DIY gamma-ray spectrometer in IEEE Spectrum (opens in new tab).

The gadget acts a little bit like a Geiger counter however is extra delicate and may determine the precise mixture of isotopes that makes the detector click on. Rosezky described the Pico because the ‘pure alternative’ for a microcontroller when creating this undertaking. He bought a small sodium iodine crystal from eBay for $40 and mixed it with a silicon photomultiplier. All this was related to a provider board, into which the Pi Pico was inserted. A gamma ray produces an electron with proportional power within the crystal, which excites the atoms because it strikes by the construction. This causes photons – mild – to be emitted, and by counting the photons, you may know the power of the gamma ray.
