A drill hole in the centre of a strong radon anomaly intersected 33 feet of 7.51%
U3O8 at 500 feet depth
The radon survey was carried out with alphameters placed under the snow.
- Although the ore-grade mineralization was at 500 feet, anomalous uranium was observed
at much shallower depths. This near surface mineralization may have given rise to the radon
anomaly observed at surface.
- This information and the attached figure were taken from Saracoglu,N; Wallis,R.H.;
Brummer,J.J.; and Golightly,J.P. 1983: Canadian Mining and Metallurgical Bulletin, vol. 76,
- Alphameters have the advantage that they remain at the sample site and collect data
over a period of days, averaging out any temporal variations.
- 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. link.
We measure: radon - radium - thoron - radon daughters - alpha radiation.
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.
