As a former nuclear engineer and a current RF engineer a wireless carrier, I can tell you that the cell phone radiation should be the least of your concern. I have used a device called A NARDA EME meter to measure radiation at cell towers and in office buildings with antennas on top. The meter measures a broad spectrum of radiation including microwave, PCS, police band, 2-way, etc. It is fun showing the "scared" building tenants that there is more radiation coming from their lunch room microwave or their laptop than from the antennas or a cell phone at close range.
Here's a little intel. When a digital (CDMA) phone is only being listened to by a user and not talked into, the transmit signal is almost nothing, so the radiation given off is practically nil. If you want your co-workers to be sensitive to your radiation fears, tell them to communicate with only short "yes"/"no" answers while on the phone. It's safer AND entertaining for you too!
