Radon, thoron and radium geochemistry can be useful in exploration for rare earth elements (REE).

  • Uranium commonly accompanies rare earth elements (REE) in commercial deposits.
  • The Mountain Pass REE deposit in California was discovered by prospectors looking for uranium. It was the major world supplier through the 1960's and into the 1980's.
  • Rare Earth deposits at the Welsford Inner Property in New Brunswick were discovered by following up geochemical and scintillometer anomalies.
  • These cases indicate that radon techniques, including radium and thoron, that we use in uranium exploration, would be useful in exploration for rare earth deposits.
  • Radon and/or radium can be determined in water and sediment samples collected from lakes and streams.
  • Radon and radon/thoron ratios can be determined instantly on the spot in soil gas.



INSTRUMENTS
  • We measure: radon - radium - thoron - radon daughters - alpha radiation.
  • The Lucas cell is recognized as the most sensitive and reliable method for these elements.
  • Our instruments are used around the world in exploration for uranium, oil & gas, groundwater and hydrothermal, and in environmental protection, health physics, earthquake prediction, and evaluation of hydrocarbon and NAPL contamination.
  • In the radon business since 1968, our latest major instrument update was 2015.
  • Modern, low-power, field-rugged electronics. Some earlier versions still working after 35 years.
  • Continuous real-time monitoring and data recording.
  • Winter and summer, from the Sahara Desert to the Canadian Shield, our instruments have faced up to severe field conditions.
  • Intrinsically safe functions.
  • Sensitive to geochemical trace levels necessary for radon in lake water and for radon-thoron isotope ratios.
  • Can work in a tent without electricity or be carried from point to point in the field.
  • 50 readings per day. Results available immediately.
  • Rechargeable battery pack good for a long day in the field and recharges in a few hours.
  • Can be operated by junior personnel if carefully supervised.
  • Same instruments used for radon and radium in soil, sediment, plant parts, rocks, water, soil gas, air, and snow, and for radon daughters in air.
  • EPA compliant.
