Abstract
The paper reports on developing a method for selective detection of molecular iodine isotopologues of 127I2, 127I129I and 129I2 in gaseous media typical for nuclear fuel cycle enterprises and atmosphere. The method proposed relates to the methods of laser–fluorescence spectroscopy and consists in the analysis of fluorescence spectra of molecular iodine isotopologues mixture. The method provides for the registration of fluorescence intensities at pre–calculated wavelengths. Copper vapor lasers emitting at wavelengths of 510.6 and 578.2 nm are proposed as a source of fluorescence excitation. The method allows for highly sensitive online monitoring of molecular iodine isotopologues (including radioactive 129I2) in technological environments that are formed as the result of processing of spent nuclear fuel, in radiochemical enterprises gas emissions, and in atmospheric air.
