After the Fukushima accident, the drawbacks of the radiometric methods for 90Sr determination were revealed. Because of the necessity of rapid 90Sr analysis, attempts have been made to develop new 90Sr measurement methods using mass spectrometry instruments, such as accelerator mass spectrometry (AMS); resonant laser ionization mass spectrometry (RIMS); inductively coupled plasma mass spectrometer with dynamic reaction cell (ICP-DRC-MS); triple quadrupole inductively coupled plasma mass spectrometer (ICP-QQQ-MS) and thermal ionization mass spectrometer (TIMS).\nFor each technique, the principles used for 90Sr analysis, and the merits along with demerits will be discussed.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"VI.
