After thousands of studies, the most that experts worldwide can determine is the radiation used for wi-fi networks, digital devices, cordless phones and cell phones is a “possible” cause of cancer. With such uncertainty, OLIVIA WANNAN asks if we are using this technology with enough caution.
As in many countries around the world, the debate about long- wave radiation has come to a head in New Zealand through the recent introduction of wi-fi networks in schools.The energy waves have been harnessed for more than a century to bring radio and television to our home, track objects by radar, microwave our food, and connect us through texts, phone calls and the internet.Yet the World Health Organisation lists this radiation as a “possible” cause of cancer, based on research showing a link between heavy cellphone use and an increased risk of developing brain tumours.Kapiti Coast parent Damon Wyman is a vocal advocate for caution. He became aware of the possible health effects of wireless technology after losing his son Ethan, 10, to cancer last August.Ethan died 11 months after being diagnosed with two brain tumours. Three months earlier, he had been given a wi-fi connected iPad.His parents later discovered he had been falling asleep with the device under his pillow.Even though it was on standby, it was still emitting bursts of radiation as it tried to connect to the router, Mr Wyman said.Doctors who saw Ethan said the tumours appeared to be about four months old, Mr Wyman said. “We’re not saying that caused it, but it seems like a bit of a coincidence.”
