"There currently is no good scientific study that determines whether or not cell towers on fire stations are hurting our members, so a study must be done," IAFF General President Harold Schaitberger said in a statement.

The group wants a ban on the installation of new cell towers, antennas and cellphone base stations until a study of their health effects is completed.

The wireless industry has consistently downplayed the health risks of "non-continuous" exposure to RF radiation from cellphones. "Critical questions concerning the health effects and safety of radio frequency microwave radiation remain," said Schaitberger. "We want answers, not the biased opinions of cellphone industry groups."

The association claims to represent more than 85 percent of professional firefighters and emergency medical personnel in the U.S. and Canada.

The group noted that most health studies are at least five years old, and generally focused on the safety of cellphones only. A new study should focus on concerns about the effects of living directly under these stations for a "considerable stationary period of time and on a daily basis."
