Plain English Summary
Researchers exposed rats to cell phone radiation at levels up to 5 W/kg (similar to older phones held directly against the head) while measuring stress hormones and brain activity markers. The study found no differences in stress responses between animals exposed to the radiation versus those that were only restrained, suggesting the radiation itself didn't cause additional stress at these exposure levels.
Study Details
Exposure of humans and rodents to radiofrequency (RF) cell phone fields has been reported to alter a number of stress- related parameters. To study this potential relationship in more detail, tube-restrained immobilized Fischer 344 rats were exposed in the near field in a dose-dependent manner to pulse-modulated (11 packets/s) digital cell phone microwave fields at 1.6 GHz in accordance with the Iridium protocol.

We conclude that the pulse-modulated digital Iridium RF field at SARs up to 5 W/kg is incapable of altering these stress-related responses. This conclusion is further supported by our use of an RF-field exposure apparatus that minimized immobilization stress; the use of conditioned/tube-trained animals and the measurement of hormonal and molecular markers after 2 h RF-field exposure when the stress-mediated effects were complete further support our conclusion.
