A report from the European Commission is expected to fine no major health risk associated with the electromagnetic fields around pylons in a report due to be published today.
Experts have examined nearly 500 studies carried out since 2009, which looked at pylons and other electronic devices like mobile phones and hospital equipment.
It comes as debate continues around Eirgrid's proposed new pylon network around the country.
The Government last week set up a review group to look at all the options on whether new cables should be installed under or overground.
Eamon Gilmore said today that the study commissioned by the Government on pylon use will continue, despite the EC report.
