George Carlo is a public-health scientist whose specialty was epidemiology. He chaired and directed Wireless Technology Research LLC, the seven-year program (1993-1999) funded by the cellular industry to research the health effects of cellular phone use. Controversial to be sure, the WTR’s findings were dismissed outright by cell phone companies. Carlo warned industry executives that “The question of wireless phone safety is unclear. Therefore, from a public health perspective, it is critical for consumers to have the information they need to make an informed judgement about how much of this unknown risk they wish to assume in their use of wireless phones. Informing consumers openly and honestly about what is known and not-known about health risks is not liability laden – it is evidence that your industry is being responsible, and doing all it can to assure safe use of its products.” In 2002 Carlo co-authored ‘Cell Phones: Invisible Hazards in the Wireless Age’ with Martin Schram.
