Abstract: A novel and rapid method has been developed for pre-concentration and measurement of <superscript>226</superscript> Ra in groundwater and discharge water samples using the latest generation triple quadrupole inductively coupled plasma mass spectrometry (ICP-QQQ-MS). Cation exchange and extraction chromatography are capable of pre-concentration factors of ~200 based on 1L samples. The sensitivity and interference removal capability of ICP-QQQ-MS was assessed from spiked groundwaters, with the introduction of He collision gas required to minimise instrument background in high-matrix samples. The technique developed is potentially capable of detecting <superscript>226</superscript> Ra activities as low as 5mBqL <superscript>-1</superscript> when combined with pre-concentration prior to measurement.<br /> (Crown Copyright © 2017.
