Review of the development in determination of 129I amount and the isotope ratio of 129I/127I using mass spectrometric measurements

An isotope dilution mass spectrometry overview: tips and applications for the measurement of radionuclides

“…Also, an important memory effect of I in ICP-MS has been reported. 183 The quantication of 129 I is usually based on the isotopic dilution technique using stable 127 I as an internal standard and the mass shi mode of the ICP-MS/MS. The initial amount of 127 I is then quantied with an external calibration.…”

“…182 The use of 125 I present in certied NIST SRMs 4407H and 4407L is also mentioned to quantify 129 I by ID because the abundance of 129 I in the CRMs is negligible. 183 5.1.2.7. Neptunium-237.…”

Atomic spectrometry update – a review of advances in environmental analysis

“…Element-or nuclide-specic reviews featured the measurement of total, inorganic and organic P in plant tissue (95 references) 118 ; mapping and speciation of P in soil (105 references) 119 ; speciation of As in traditional Chinese medicines, including medicinal plants (79 references); 120 and determination of 129 I concentrations and 129 I/ 127 I isotope ratios in environmental samples (96 references). 121 Analytical methods for the determination of PTEs in plants were the topic of two reviews. The rst (206 references) focused 122 on medicinal plants and emphasised the need for more widespread QC to ensure the products sold are t for consumption.…”

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…The long-lived radionuclide 129 I accumulates in the environment from spent nuclear fuel reprocessing and nuclear accidents, and determining its concentration is important in assessing the safety of waste repositories. A summary paper by Kim et al 194 documented the key mass spectrometric techniques used to measure 129 I relative to 127 I: TIMS, AMS and ICP-MS. The paper covered the purification methodology and the required loading chemical substrates for each technique.…”
