In the assessment of exposure in the living environment after the nuclear power plant accident, external and internal doses due to nuclides that have entered the room and drifted into the air or deposited on the floor surface are assessed in addition to external doses from outdoor deposited nuclides for the time spent indoors. However, in reality, in addition to these, the effects of re-suspension of nuclides deposited on floor surfaces also occur. In this study, we evaluate how the results of exposure dose assessment differ between the case where resuspension is not taken into account (conventional method) and the case where it is taken into account (new method), and to what extent the effects occur.
