Results of in-vivo and in-vitro measurements and dose assessments of foreign citizens returning from Japan after Fukushima Daiichi NPP accident were made available to EURADOS Working Group 7 "Internal dosimetry" by bioassay laboratories in Europe and Canada. Due to the lack of early measurements of the internal contamination in the members of public in Japan, further analysis and processing of the data from the EURADOS survey can be considered as a complementary source of information contributing to clarify the situation. In this paper, the degree of correspondence between the measurement results and values estimated from the radionuclide air concentrations data is shown for certain locations and radionuclides. Case study approach is applied for determining intakes of radionuclides by monitored individuals, taking results of their in vivo counting in to calculation. Data to support assumptions taken to dose estimates based on atmospheric dispersion models are given. Also, scarce early data on the ratio of radioiodine and radiocaesium intakes not available elsewhere are presented, as well as contributions of short-lived radionuclides to the early dose.
