In geochemical prospecting using stream sediments and soils, radium is more direct than uranium.
-
At the
Faraday Mine,
radium in the A-horizon and B-horizon and uranium in the B-horizon all
respond well to the presence of underlying ore.
As expected, anomalies in all three cases are shifted somewhat downhill.
Uranium in the A-horizon, on the other hand, shows no relationship to the underlying ore, but
gives a strong anomaly in the swampy soil lower down the hill.
-
Also in the Bancroft area, in organic stream sediments,
we find that upstream uranium mineralization is more closely reflected by radium than by
uranium.
-
Radium is determined in soils, sediments and water using the same Lucas cell system as for
radon.

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 health physics, earthquake prediction, and evaluation of hydrocarbon and NAPL contamination.
-
In the radon business since 1968, our latest major instrument update was 2011.
-
Modern, low-power, field-rugged electronics.
-
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.
-
40 readings per day. Results available immediately.
-
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.
