Lung Deposition From Icrp 30 - Panasonic PT-DZ12000U Operating Instructions Manual

Ventilation rates of work areas for health physics and industrial
hygiene requirements is typically 6 to 7 volume turnovers per
hour.
Calculate the ventilation rate in CFM to ventilate a room at 7
volume turnovers per hour given room dimensions of 30 feet by
30 feet by 10 feet. Volume of the room is 30 x 30 x 10 = 9,000
cubic feet. Seven volume turnovers per hour would be 7 times
9,000 cubic feet or 63,000 cubic feet per hour (1,050 CFM)
room ventilation rate.
