For this study, Bassen tested a second-generation iPod Nano, a second-generation iPod shuffle, a fifth-generation iPod Video with a 30-gigabyte hard drive, and a standard iPod with a 15-gigabyte hard drive and dock connector.Hopefully, the American Heart Association will pick up on this story and print a retraction to their earlier fear-mongering quiz.
For all of them, data taken at 0.5 and 1.0 cm from the case showed a field of 0.2 micro-Tesla or less, with a highly localized 100 kilohertz sinusoidal signal.
The fields existed only in an area of about 1 cm2 and were not measurable at distances greater then 1 cm from the case, Bassen said.
He also found no measurable fields near the earphone cable, except at the earphone itself.
