For that, you need something like this gamma-ray spectroscope ... [mihai.cuciuc] took inspiration for the Pomelo from this DIY spectrometer as well as the CosmicPi.
The tour ends with gamma rays, the potentially deadly radiation ... To find out more about the spectrum, see the links in Resources. To convert metric measurements discussed in this feature ...
Then the principal factors of a Mössbauer spectrum are illustrated with spectra taken from research work. Finally a bibliography of books and web sites is given for further and more detailed ...
We don’t know why [stoppi71] needs to do gamma spectroscopy. We only know that he has made one, including a high-voltage power supply, a photomultiplier tube, and–what else–an Arduino.
