A mathematical model was applied to continuous indoorand outdoor particulate matter (PM) measurements to estimatesource strengths for a variety of prescribed humanactivities that resuspend house dust in the home. Activitiesincluded folding blankets, folding clothes, dry dusting,making a bed, dancing on a rug, dancing on a wood floor,vacuuming, and walking around and sitting on upholsteredfurniture. Although most of the resuspended particlemass from these activities was larger than 5 
m in diameter,the resuspension of PM2.5 and PM5 was substantial, withsource strengths ranging from 0.03 to 0.5 mg min-1 for PM2.5and from 0.1 to 1.4 mg min-1 for PM5. Source strengthsfor PM > 5 m could not be quantified due to instrumentlimitations. The source strengths were found to be afunction of the number of persons performing the activity,the vigor of the activity, the type of activity, and thetype of flooring.
