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.
