Comparative assessment of the sorption properties of carbon filters used in the ventilation system of NPP, using 131I and 127I
Comparison of the methods for determining sorption properties of the SKT-3I adsorbent using 131I and 127I were carried out. 127I was determined in the carbon matrix by the characteristic X-ray emission of the K-series of iodine atoms excited by gamma radiation with an energy of 60 keV from the radio...

| Summary: | Comparison of the methods for determining sorption properties of the SKT-3I adsorbent using 131I and 127I were carried out. 127I was determined in the carbon matrix by the characteristic X-ray emission of the K-series of iodine atoms excited by gamma radiation with an energy of 60 keV from the radioactive source 241Am. 131I was determined by the registration of the gamma lines with energy of 364 keV. The correlation coefficient was determined for these methods, which allowed asserting that both methods give an adequate estimation of the sorption properties of SKT-3I. This makes it possible to use the method with 127I to estimate the sorbents purification coefficient of carbon filters used in ventilation systems at Ukrainian NPPs. |
