Determination of 129I in seawater and some environmental materials by neutron activation analysis

A review on speciation of iodine-129 in the environmental and biological samples

“…A combustion method has also widely been used for the separation of iodine from solid samples [121][122]. In this method, sample is combusted at higher temperature (>800°C), I ratio of 10 -10 ) has been reported [120].…”

Critical comparison of radiometric and mass spectrometric methods for the determination of radionuclides in environmental, biological and nuclear waste samples

“…For removal of the interference, the iodine needs to be separated from the sample before the neutron irradiation; a detection limit of 1 μBq has been reported [203,207].…”

The Potential Of I-129 as an Environmental Tracer

“…Iodine is decomposed into iodine atom and ionized to positive iodine ion at a temperature ~6000−8000 K. It is then extracted from the plasma into a high vacuum of the mass spectrometer via an interface. The extracted ions are separated by mass filters of either quadropole type time-of-flight or combination of magnetic and electrostatic sector and measured by an ion decetor (Hou et al, 2009 (Hou et al, 1999). They have to be removed from the sample before irradiation to avoid nuclear interferences.…”
