Characterization of an extraction chromatographic resin for the separation and determination of 36Cl and 129I

The Potential Of I-129 as an Environmental Tracer

“…Recently extraction chromatographic resins for the separation and determination of 36 Cl and 129 I have been developed. First results show a promising potential to use the resins within the context of the monitoring of nuclear installations -during operation and especially during decommissioning (Zulauf et al, 2010).…”

Preliminary evaluation of 14C and 36Cl in nuclear waste from Ignalina Nuclear Power Plant decommissioning

“…Activity concentrations of 36 Cl in radioactive waste samples can be determined in a similar way as for 14 C using LSC techniques [16][17][18][19]. Digesting of radioactive waste samples can be performed using concentrated acids and acid mixtures as well as various modifications of the Fenton reaction and thermal destruction.…”

“…A number of procedures have been tested to select a method to measure 36 Cl in the spent ion-exchange resins and irradiated-graphite [17][18][19] (Fig. 3).…”

“…The basic principles of waste sample decomposition, 14 C and 36 Cl separation, and purification procedures are reviewed [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The most common methods of the sample decomposition, including acid digestion, wet oxidation, and catalytic combustion, were used.…”

Liquid scintillation counting for determination of radionuclides in environmental and nuclear application

“…Although the analytical behaviour of rhenium is quite similar to that of Tc, these elements can behave quite differently under certain conditions; precautions need to be taken if rhenium is used as a tracer. 99m Tc, obtained from a 99 Mo-99m Tc generator has been used widely as a yield tracer in the radiochemical separation of 99 reprocessing plants or nuclear accident sites) [122][123]. For determination of 129 I in the ion exchange resin used in the purification of the primary circuit of nuclear power plants, the iodine in the resin is first extracted using NaOCl.…”
