Outline of Final Research Achievements

After Fukushima nuclear power plant accident, it has raised the need to determine the quantities of radionuclides in order to assess their potential impact on public health. A mass spectrometry is used for the determination of many long-lived radionuclides with low specific activities in biological samples. Human tooth enamel provides a nearly permanent and chronological record of an individual’s environmental exposure during development. We have conducted to make procedure for analysis of elemental distribution in deciduous enamel of children to retrospectively evaluate the prenatal radionuclides exposure. We demonstrates the validity of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) to provide elemental distribution information in dental tissues for Fukushima’s children.
