We have studied contribution of H 2 plasma etching to radial profile of amount of dust particles generated due to interactions between H 2 plasmas and graphite target in a divertor simulator. Dust fluxes of spherical particles and flakes are the maximum at the distance r= 100 mm and 120 mm from the centre axis of the plasma column, respectively. From ion density and dust flux, we have deduced etched volume of deposited dust particles due to H 2 plasma irradiation. Sum of the etched volume and measured volume of spherical dust particles is almost constant for r< 120 mm and decreases with increasing r for r> 120 mm, whereas that of flakes is the maximum at r= 120 mm. H 2 plasma etching significantly reduces size of dust particles for r smaller than 100 mm.
