Measures the radiation emitted by a material, such as lead, identifying which and how many radioactive elements are present inside.
The alpha spectrometer, as implied by its name, is able to detect alfa particle radiation emitted by radioisotopes that ‘’decay’’, meaning that they pass from an unstable condition to a more stable one, thereby emitting an alpha particle consisting of two neutrons and two protons. The spectrometer allows to find which radioactive element has produced emissions and to determine its abundance. Lead emits alpha radiations in variable intensity, based on its age.
