Hello everyone. Is there a type of radiation detector that can tell the energy level? I have a basic understanding about Geiger counter and Scintillation counter, they seem only tell the incident particle number. The testing environment may contain Thorium series, Uranium series and Actinium series decay chain. The purpose is trying to find out what particles are there, or at least what decay (energy level) is in there mainly. Please let me know what kind of radiation detectors suits most. Thank you!
