....there is a proposal for a tower to go up above a store at a busy intersection in my area. Can you point me to some websites, articles or information about: What long term effects the transmissions could have on people, transmission frequencies. The owner is talking about a 20 year lease from the cell phone carrier. Children will soon be using that store as they buy snacks and supplies. And would you feel safe working in that store for years? Thanks for any information.
