View Original AbstractThis study found no memory or learning deficits in mice exposed to low-level 900 MHz radiation for 10 days.
Plain English Summary
Researchers exposed mice to 900 MHz radiation (similar to early cell phone signals) for 45 minutes daily over 10 days and tested their ability to learn and remember spatial tasks. The mice showed no differences in learning performance or memory compared to unexposed control mice. This suggests that low-level cell phone radiation at these specific conditions doesn't impair basic cognitive functions in mice.
Study Details
There is some concern that short-term memory loss or other cognitive effects may be associated with the use of mobile cellular telephones. In this experiment, the effect of repeated, acute exposure to a low intensity 900 MHz radiofrequency (RF) field pulsed at 217 Hz was explored using an appetitively-motivated spatial learning and working memory task.

These results suggest that exposure to RF radiation simulating a digital wireless telephone (GSM) signal under the conditions of this experiment does not affect the acquisition of the learned response. Further studies are planned to explore the effects of other SARs on learned behavior.
