The operation principle of spectrometers is based on the registration of gamma-quanta, beta or alpha particles emitted by radionuclides contained in the samples by an appropriate type of detector, which outputs an electrical impulse with amplitude, which is proportional to the energy of the detected gamma-quantum, beta or alpha particles.
