A study led by University of Galway has used gamma rays to create more accurate maps of peatlands nationwide.

Gamma Rays are invisible, high-energy photons released during natural radioactive decay of material in rocks and soils.

Peat soils have a unique ability to block this type of naturally occurring radiation.

Using a special sensor on a Tellus survey aircraft, the research team has now created a more accurate map of peaty soils across the country.
