Last year, the Mobile Phone Radiation Warning Bill suggested putting the following message on phones: "Warning: this device emits electromagnetic radiation. Users, especially children, should keep this device away from the head and body."
However, this measure has yet to be implemented despite calls from the Irish Doctors' Environmental Association.
The Department of Health does not recognise electro-sensitivity as a disability and has no plans to do so in the near future.
A spokesperson said there was still no scientific basis to link its symptoms to electromagnetic fields exposure.
However, in June 2011, the World Health Organisation and the International Agency for Research on Cancer classified the radio frequency electromagnetic fields emitted by mobile phones as "possibly carcinogenic to humans".
In the light of these findings, the Chief Medical Officer of the Department of Health and Children strongly advised that children and young people should be encouraged to use mobile phones for "essential purposes only".
