Dad rock lives! iPods won't hurt your heart

A Food and Drug Administration-led study refutes claims that the magnetic fields produced by Apple iPods and other such portable music devices interfere with cardiac pacemakers.

A report from the research team, which tested four iPod models, appears in BioMedical Engineering OnLine.

A report from a Michigan high school student -- who teamed with a couple of heart doctors -- is among earlier research that generated some buzz about whether iPods could muck up pacemakers and raised the idea of putting warning labels on portable music devices.

From a BioMed Central press release: "Using a 3-coil sensor, the team measured the magnetic field produced by the iPod at a distance of around 5 to 10 millimeters. They obtained readings for the magnetic field at various specific and small regions 10 mm from an iPod. The peak magnetic field strength was 0.2 millionths of a Tesla, a value hundreds of times lower than the levels capable of interfering with a pacemaker."

Howard Bassen, a researcher with the FDA, said in a statement: "Based on the observations of our in-vitro study we conclude that no interference effects can occur in pacemakers exposed to the iPods we tested."

Meanwhile, iPods continue to enjoy great success, most recently highlighted by the spate of new iPod-related offerings at the big CES show in Vegas.

Studies have also piled up in recent years regarding the health impact of other portable devices, such as cell phones.
