In all seriousness its nothing to do with computing (other than computing exposure to mobile phones, monitors and wireless networks), you need someone who understands wireless propagation, antenna design, field strengths, the behaviour of EM radiation incident on living tissue and to know a lot more about what the antenna is for, what its propogation field looks like etc. If I had to suggest anywhere to start asking it might well be local radio amateur groups. They can at least help you ask the smart questions that differentation a random wireless access point (which you can probably stick in your mouth for a year and transmit - not that I'd advise that), a mobile phone antenna where its probably not a good idea to stick it in your mouth but nobody is sure yet, a mobile phone mast (which is considered in some jurisdictions as sufficiently arm-wavingly unclear that to be on the safe side policy is to keep them away from built up areas), and sticking your head in a microwave oven (which is known to be very stupid indeed).
