Mobile phone health threat is very real

HUGH SHEEHY (Irish Examiner letters, March 24) says there is no scientific evidence that mobile phone systems have negative health effects.

This is not true. Various mainland European studies have found that red blood cells are ‘lumped’ by mobile phone use, cognitive functions are influenced by normal levels of radiation from mobile phone masts and there is damage to DNA.

Nor is it true that all countries have concluded there are no damaging effects. Nobody denies the heat effect of radiofrequent radiation. However, there is debate about the reality of radiofrequent radiation sickness because the results of research are not consistent and the working mechanism is not known.
