-
The anomaly is shifted downhill, as is normal in geochemical soil surveys.
-
Going downhill from the ore (pegmatite) the first response is shown by radon in snow.
-
The next response is shown by radium in the A and B horizons, and by
uranium in the B horizon.
-
The response of uranium in the A horizon is further downhill.
-
At the bottom of the hill in a swampy area at the spring all indicators are
high. High radon values in snow here are due to high radium values in the
underlying soil.
- Our instruments have the advantage of instant results at the sample site,
with the possibility of immediate follow-up and checking.
- Our instruments also determine thoron, and the Rn/Tn ratio is important in recognising
false anomalies due to soil permeability.

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.
