Patent number: 10281595Abstract: A method and an apparatus for distinguishing radionuclides are disclosed. The method comprises the steps of: receiving energy generated in one or more radioactive elements; applying energy as a weight for each channel to spectrum of the received energy; and distinguishing the one or more radioactive elements on the basis of the spectrum of the spectrum to which the weight is applied. A radioactive element having an energy value corresponding to a peak value of the spectrum of the energy to which the weight is applied, as an energy value of a Compton edge, is distinguished as the one or more radioactive elements. According to the present invention, it is possible to more accurately monitor radiation even while using a plastic scintillator, and further to improve energy resolution of a plastic scintillator.Type: GrantFiled: May 11, 2015Date of Patent: May 7, 2019Assignee: KOREA INSTITUTE OF NUCLEAR SAFETYInventors: Hong Suk Kim, Chang-Su Park, Chang-il Choi, Chul Hee Min, Wook-Geun Shin, Hyun-Cheol Lee, Jeong Wan Kwon, Hyungjoon Yu, Ah Reum Kim, Hyeon-Jun Choi, Hyunseok Lee
