Quirino Balzano, Oscar Garay, Frances R. Steel · 1978
This 1978 study tested how VHF portable radio transmitters heat human tissue using realistic phantom models of the head and body. Researchers found that a 6-watt portable radio held 0.2 inches from the mouth caused minimal heating (less than 0.1°C) in simulated brain tissue. The study revealed that actual tissue heating was much lower than expected because the antenna's strong static fields collapse at the air-body interface.

This review paper examined health complaints from people living near cell towers and base stations, finding reports of headaches, sleep problems, depression, and other symptoms despite industry claims that radiation levels meet safety standards. The researchers concluded that these symptoms may represent 'microwave sickness,' a condition first identified in 1978, and called for more research considering total ambient radiofrequency exposure from all sources.
