The effect of the 1/6 G environment on the atmospheric\nsuspension was evaluated by means of the cutoff value of an elutriator; the cutoff value in the 1/6 G\nshould be 6 times larger than at the earth’s surface. The results of our experiment confirmed that\nthe falling velocity of SPM in a 1/6G approximates Stokes’ law, and the falling time is inversely\nproportional to the force of gravity. Numerical computation suggested that residual SPM in a\nconvection-free room becomes high in a low-gravity environment or in a high-ceilinged room. These\nresults suggest that once lunar dust intruded into a lunar base, it would take a considerably long\ntime to clean up. Since the suspension time of SPM is different according to the particle size, the\nexposure risk of SPM will also vary according to the particle size. Considering that the risk depends\nonly on the drifting time, the actual influence of low gravity on fine particles (Dp ???? 1.0 mm in\ndiameter) and on large particles (Dp > 10 mm) in a 1/6G would be negligible. In contrast, for\nmedium sized particles (2.5 < Dp ???? 10 mm) the difference in the drifting time between that on the\nearth and on the lunar surface is much larger than can be confirmed with the senses. Safety\nprecautions used for this size of particle on the earth should be altered on the lunar surface.","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Accepted:
