Why Portable Neutron Spectrometrie Matters

Neutron radiation is present in many kritial environments: nuclear reactors, particlee akcelerators, medical raditerary facilities, and even cosmic radiation at high altitudes. Traditional stationary spektrometers require samples to be brough to tho the instrument, delaying results and missing transient events.
