Within a week of installation many firefighters developed unusual symptoms of headaches, fatigue, insomnia, memory loss, confusion, nausea and weakness. After a time, firefighters in stations with adjacent cell towers were found to have forgotten CPR or became lost responding to a fire in a city they grew up in.
A neurologic study was commissioned by the International Association of Firefighters (IAFF), led by Dr. Gunnar Heuser, to determine if there was any evidence of brain dysfunction in those exposed for long periods to first responder cell towers. Firefighters then began fighting cell towers as well as fires.
