Intakes of radionuclides are estimated from monitoring results obtained by whole body counters or bioassay for personal dose management and internal dosimetry in case of an accident. In this study, we progressed the development of a function estimating intakes of radionuclides as part of development of an internal dosimetry code which is in accordance with the ICRP 2007 Recommendations. In FY2018, we built a basic function estimating intakes using the latest biokinetic models with a maximum likelihood method based on the conceptual design performed in HY2017. The quality of the basic function was assessed by comparison of the results by this function to literature data. In the presentation, we will report the method of estimating intakes and the result of quality assessment of this function.
