Description

<p>90Sr (approx. 29-years half life time) is a beta emission radionuclide and one of the typical fission products produced from uranium fuels. 90Sr is a pure β-ray emitter nuclide and does not emit gamma-rays; thus it is difficult to measure 90Sr compared with γ-ray emitted radionuclides. For the demand of rapid measurement of 90Sr, various analytical methods have been reported. Herein, these analytical systems for 90Sr were reviewed, in particular, the application of inductively coupled plasma quadrupole mass-spectrometry (ICP-QMS) for 90Sr was focused on. The studies on ICP-MS techniques have been progressing since Fukushima Dai-ichi Nuclear Power Plant Accident.</p>
