I have decided not too be too concerned. As the Philips article states, they claim the amount released from a projector bulb (0.01 - 0.03) falls well within the acceptable amount for people to be "Constantly working around (upto 0.025 is fine for everyday work, 8hrs a day 7 days a week) so an hours exposure should pose no real threat.
Also, the amount which PEL see's as being safe without complications is 0.1, which the amount in the projector falls well below. The thing that made me relax also, is I probably have more Mercury in my fillings, and at any stage a flouresent bulb (In TV's, coputers, energy lights) may break at anytime, it should be fine. I even recall having dropped a flouresent lamp and it shattering on my arm, so why should I be concerned now???
