A radiation detection sensor was developed and characterized by combining three types of CsI(Tl) scintillators and an array-type SiPM to detect the radioactive contamination of discharged water in real time. The characterization results showed that type 3 exhibitedthe most desirable characteristics in response linearity (R-square: 0.97889) according to detection sensitivity and incident radiation dose. Furthermore, in terms of spectral characteristics, type 3 exhibited 16.54% at 0.356 MeV (the emission gamma ray energy of 133Ba), 10.28% at 0.511 MeV (the emission gamma ray energy of 22Na), 9.68% at 0.356 MeV (the emission gamma ray energy of 137Cs), and2.55% and 4.80% at 1.173 MeV and 1.332 MeV (the emission gamma ray energies of 60Co), respectively. These measurements con-firmed the good energy characteristics. The results were used to evaluate the spectral characteristics and energy linearity in a mixedsource using type 3 with the best detection characteristics. It was confirmed that the gamma ray peaks of 133Ba, 22Na, 137Cs, and 60Cowere well resolved. Moreover, it was confirmed that R-square, which is an indicator of energy linearity, was 0.99986. This indicates a good linearity characteristic. Based on this study, further commercialization studies will contribute to measurements in real time andto the management of the contamination caused by radioactive wastewater or radioactive material leakage, which originate from facil-ities that use radioactive isotopes or care facilities.
