Our Expertise

RadonEx are the world experts in the application of Electret Inonization Chamber (EIC) radon surveys to uranium and REE exploration.

Our EIC radon surveys have accelerated and advanced uranium exploration projects in various geological settings:

  • Classic sandstone unconformity-type terrains: Athabasca Basin, Thelon Basin and Hornby Basin
  • High-level granitic terrains such as Central Mineralisation Belt of Labrador
  • Sandstone-hosted environments like the Karoo of Southern Tanzania
  • Continental volcanic terrains such as the Baker Lake Basin

RadonEx Projects


  • Patterson Lake South Discovery in the Athabasca Basin – RadonEx’s unique Radon-in-water survey was critical to the biggest new mineral discovery in the world in 2013.
  • Mkuju Uranium Project, Southern Tanzania – In 2012 RadonEx’s RFM surveys outlined several sandstone-hosted uranium drill targets.
  • Anna Lake Deposit in the Central Mineralization Belt of Labrador – RadonEx’s RFM surveys lead directly to the discovery and delineation of the Anna Lake Uranium deposit in 2007-2008.
  • Middle Lake Property, using the EIC system RadonEx devised a way to integrate radon in lake water, lake sediment, bog water and ground RFM surveys in order to acquire a seamless body of radon measurement data.
