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.

Gamma-ray spectroscopy is a powerful analytical technique used to identify and quantify radioactive isotopes by measuring the energy and intensity of gamma rays emitted from a sample. This ...

A study introduced a numerical simulation method (NSM) that calculates the efficiency of gamma-ray spectrometry setups, particularly for truncated conical radioactive sources. This method allows ...
