dc.description.abstractOdnosom 134Cs/137Cs u nekom uzorku utvrđuje se porijeklo 137Cs, globalni fallout ili reaktorski akcident. Njihova detekcija i razdvajanje NaI(Tl) detektorom otežana je bliskim energijama zraka (605 keV i 662 keV), kao i zracima bliskih energija iz prirodnih radionuklida, zbog čega se nameće potreba razvoja koincidentnog metoda mjerenja. Koristeći 2 detektora spektrometra PRIPJAT (∼180°) izvor 134Cs razmatran je u integralnom, nekoincidentnom i režimu dvostrukih koincidencija.sr
dc.description.abstractThe origin of 137Cs, whether it was generated as a global fallout or reactor (Chernobyl) accident, is determined with assessment its relationship with 134Cs. 134Cs is artificial radionuclide, produced in nuclear power reactors, with a half-life of 2.1 years. Since the data on 134Cs activity in Montenegro weren’t publish after the Chernobyl disaster in 1986, there is no information about relation between these two radionuclides and therefore its detection in the Montenegro’s environment is not possible nowadays. Their detection (134Cs and 137Cs) and separation with NaI (Tl) detector is aggravated with close energies of gamma rays (605 keV and 662 keV), as well as with rays of close energies from natural radionuclides, causing a need for the development of coincidence measurement method. Using 2 detectors of spectrometer Pripyat (∼180°), 134Cs source is analyzed in an integrated, non-coincidence and the mode of double coincidences. This paper presents the results of the initial research for the establishment of coincident detection methods and determination of artificial radionuclide 134Cs activity in samples from the environment.en
