Over the past year, the Chicago Tribune hired RF Exposure Lab in San Marcos, Calif., to measure 11 different cellphone models for radiofrequency radiation.

RF Exposure, an accredited testing lab recognized by the Federal Communications Commission, has conducted radiation tests for 15 years for wireless companies seeking FCC approval for new products. Jay Moulton, the lab's owner and former engineering director for chip-making giant Qualcomm, conducted the Tribune's tests.
