We have some reports of the use of radon in groundwater exploration.
  
Our instruments provide radon-thoron ratios as well as radon. These ratios have proven useful in exploration
for uranium and should also be applicable to groundwater.

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.
