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.

This book has a page (p. 86) on radon including several references.
We measure: radon - radium - thoron - radon daughters - alpha radiation.
is recognized as the most sensitive and reliable method for these elements.
Intrinsically safe functions.
Sensitive to geochemical trace levels necessary for radon in lake water and for radon-thoron isotope ratios.
- immune to beta and gamma radiation.
- one monitor works with a number of (less expensive) detectors.
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 etc.
Same instruments used for radon and radium in soil, sediment,
plant parts, rocks, water, soil gas, air, snow, food, and for radon and thoron daughters in air.
Winter and summer, from the Sahara Desert to the Canadian Shield, our instruments have faced up to severe field conditions.
In the radon business since 1968, our instruments are updated regularly with the most recent major re-design in 2015.
Modern, low-power, field-rugged electronics. Some earlier versions still working after 40 years.
Continuous real-time monitoring and data recording.
RS232 port/pc software.
- User programmable measurement intervals, sample and count periods and alarm level settings.
Can work in a tent without electricity or be carried from point to point in the field.
50 readings per day. Results available immediately.
Portable. 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.
EPA and CE Mark compliant.
