[2J16] Dose assessment for residents in the residential environment considering the transfer of substances between indoor and outdoor after nuclear accidents
(3) Resuspension of indoor deposited particles
Keywords:Resuspension, Indoor, Nuclear Accidents
Among the exposure pathways when staying in residential environments in areas around power plants after the nuclear power plant accident, exposures during stays indoors can be divided into those caused by radioactive materials outdoors and those caused by radioactive materials that entered indoors from outdoors. When evaluating internal exposure due to the resuspension of particles containing radioactive materials deposited on indoor floor surfaces after entering from outdoors, the resuspension particle concentration distribution model and coefficients may differ from those outdoors because the materials and airflow field of the deposited floor surfaces differs from those outdoors. In this study, in order to construct an indoor particle resuspension model, resuspension particle concentration and resuspension coefficients for various conditions were evaluated for materials used for indoor floors and air velocity fields by simulation and actual measurement.
