from mixing, drilling and cutting are measured. Emission factor and exposure during these simulated activities are estimated. Average PNC were 4–15 times higher over the background PNC during the activities. Average exposure doses varied up to about 38-times during the studied activities. Negligible fraction of PNCs for particles >300 nm was found during all activities.
