There are different types of radiation detectors (gas-filled, semiconductor, scintillator etc.) and various working principles (ionization, electron-hole pair production, excitation) used in radiation detection. It is important that any detector is selected according to its intended use and that the detector is operated under appropriate conditions. NaI(Tl) scintillation detectors are widely used in nuclear spectroscopic studies due ... necessary to know the response function of the detector against radiation under the expected operating conditions and ...
