Pure beta-emitting 79Se is one of the long-lived fission products that might release to the environment due to the nuclear accident at Fukushima Daiichi Nuclear Power Plant (FDNPP). A reliable and simple determination method of the radionuclide is important for proceeding the disposal of the wastes obtained from the decommissioning of FDNPP. We developed a new analytical procedure for the measurement of 79Se by inductively coupled plasma triple quadrupole mass spectrometry (ICP-MS/MS). All interferences that potentially interfere in the measurement of 79Se could be effectively removed by the chemical separation pretreatment and ICP-MS/MS. The method is tested with inactive concrete to verify the interference removal efficiency. Also, the analytical figures of merit such as detection capability etc. are reported.
