Hypersensitivity symptoms associated with exposure to cellular telephones: No causal link.

View Original AbstractPeople reporting cell phone sensitivity experienced more symptoms during fake exposure than real exposure, suggesting symptoms aren't directly caused by RF radiation.
Plain English Summary
Finnish researchers tested 20 people who claimed to be sensitive to cell phone radiation by exposing them to both real and fake cell phone signals in controlled conditions. The study found that participants reported more symptoms during fake exposure than real exposure, and none could tell when phones were actually on or off. This suggests that while people genuinely experience symptoms they attribute to cell phones, the phones themselves aren't causing these effects.
Study Details
The hypothesis that there exist hypersensitive persons who perceive subjective symptoms from radiofrequency (RF) fields emitted by hand held mobile phones (cellular phones) was tested using double blind provocation experiments. We also tested whether sensitive subjects are able to determine whether the phone is on or off by sensing RF fields.
The study group consisted of 20 volunteers (13 women and 7 men) who reported themselves as being sen...
The results of the study indicated that various symptoms were reported, and most of them appeared in...
Hence, we conclude that adverse subjective symptoms or sensations, though unquestionably perceived by the test subjects, were not produced by cellular phones.
