CFL bulbs -- Are Mercury levels Dangerous?

Ron Sam

In response to Thomas's concerns of CFL lamps being dangerous...

A CFL containing 5 mg of mercury breaks in your child’s bedroom that has a volume of about 25 m3 (which corresponds to a medium sized bedroom). The entire 5 mg of mercury vaporizes immediately (an unlikely occurrence), resulting in an airborne mercury concentration in this room of 0.2 mg/m3. This concentration will decrease with time, as air in the room leaves and is replaced by air from outside or from a different room. As a result, concentrations of mercury in the room will likely approach zero after about an hour or so.
