Ethan Wyman, 11, died of brain cancer earlier this year, and his parents are pointing the finger at his exposure to wireless signals. Their son's school is listening, and has sent a survey to parents asking if the wireless service should be removed.

Two New Zealand parents think a school's Wi-Fi may have killed their son.

Ethan Wyman, 10, died of brain cancer earlier this year after an 11-month battle.

His parents now want Wi-Fi removed from his school because they believe students there are being exposed to radiation that could lead them to suffer Ethan's fate.

Though numerous studies have found that Wi-Fi signals do not present any public health risk, Ethan's Te Horo School has sent a survey to all parents asking if the wireless internet should be removed.

A decision is expected Saturday.

Ethan's father, Damon Wyman, told New Zealand's The Dominion Post his son received the diagnosis of brain tumors three months after he was given an iPod with a Wi-Fi connection.

The parents later learned that Ethan had been falling asleep with it under his pillow.

"We're not saying that caused it, but it seems like a bit of a coincidence. Most people would be very cautious about giving their 5-year-old a cellphone - well, this is 30 kids in a classroom (being exposed) to the same thing," Damon Wyman told the newspaper, adding he still has two children at the school.

The controversy prompted New Zealand's Ministry of Health to restate its position that electromagnetic fields from Wi-Fi did not pose a health risk.

Scientific studies have found no definitive link between childhood cancer and exposure to electric and magnetic fields.
