Mobile phone radiation may damage cells by increasing the forces they exert on each other, scientists have said.
The finding could be the key to claims that mobile phones cause cancer and other health problems.
Swedish physicists looked at the effect of electromagnetic radiation on red blood cells using a mathematical theory reported.
Experts cautioned that the finding was theoretical and said there was no evidence of a danger to health.
There have been suggestions that mobile phones can cause brain tumours and Alzheimer’s disease, but research has been inconclusive.
