But doctors who conducted a six year study on wireless phone safety say the convenience comes at a high health cost. We also have evidence of an increased risk in rare brain tumors that are on the outside of the head that grow inward. The concerns are prompting a market onslaught of devices to cut-down on alleged dangerous radiation. One device is called microsafe. It fits over the cell-phone antenna.
Inventors claim it shields internal organs by reducing microwave emissions.
The gadget hasn't been proven effective. The cell-phone industry is under pressure and has decided to toughen its own standards. Manufacturers have reported radiation levels to the FCC since 1996. New regulations that go into effect next month will make that information available and understandable to consumers. Officials at Richardson-based Ericsson say it's a good idea.
