Accurate technetium-99 determination using the combination of TEVA resin pretreatment and ICP-MS measurement and its influence on the Tc-99/Cs-137 scaling factor calculation

Development of a single method for direct measurement of multiple radionuclides using ICP-MS/MS

“…Technetium-99. Technetium-99 has been effectively measured using LSC 26,27 and increasingly by ICP-MS. [28][29][30] In both cases, measurement is preceded by chemical separation, with effective techniques including co-precipitation, 31,32 solvent extraction, 31,33 anion exchange 34 and extraction chromatography using TEVA resin [35][36][37] and more recently TK201 resin. 38 Both 97 Tc and 98 Tc are suitable long-lived tracers, with 97 Tc favoured because of the possibility of 98 Tc 1 H polyatomic formation overlapping at m/z ¼ 99.…”

A quantitative method study on pertechnetate in aqueous solution using Raman spectroscopy

“…Tc is a pure b À emitter, which can be measured by radiation counting. There are several analytical methods for Tc determination with extremely low limits of detection, like inductively coupled plasma mass spectrometry (ICP-MS), [1][2][3][4][5][6] radiochemical analysis methods, 7,8 total reection X-ray uorescence, 9 and so on. K. L. Shi et al 10 reviewed the studies on the determination of 99 Tc in environmental samples.…”
