Uranium prices have risen significantly in recent years. Along with rising prices for Uranium, exploration for new sources of uranium has been on the increase.


WELLOG has teamed up with a company that has been producing uranium probes for many years. The probes are used for logging short exploration holes in uranium mines and can also be used for measuring the radiation in exploration of uranium mines, stock piles and tailings piles.


Geiger Mueller (GM) tubes have been used for detecting gamma radiation for many years. GM tubes are used on many hand-held survey meters such as those produced by Ludlum Instruments. Exploration geologists often need a probe that is capable of measuring gamma radiation in short boreholes.


WELLOG offers a solution. The WELLOG GM Uranium Probe will connect to standard Ludlum Instruments survey meters.  


Operation is simple. The existing GM probe is disconnected and the WELLOG GM Uranium Probe is connected to the survey meter. The survey meter is turned on and the range switch moved to the appropriate scale. The probe is inserted into the borehole and readings are made that indicate different gamma count rates. Gamma count rates are related to the percentage of Uranium contained in the host rock. Many geologists have samples of Uranium that contain a known percentage of Uranium. Using samples having a known percentage of Uranium and noting the count rate, allows for conversion of count rate to percent Uranium. This process allows exploration geologists to evaluate the economic potential of Uranium deposits quickly and easily.




WELLOG also has a version of GM Uranium Probe that has a “T” handle and is designed to penetrate stockpiles for purposes of Uranium valuation.




In Situ soil Measurements.


Radioactive contamination can be measured in areas where water channels have re-deposited contaminants at various layers below the surface. Examples such as the recent contamination of soil sediment in areas surrounding nuclear power plants in Japan are applications where a soil penetrometer is useful. In-situ measurements can be made instantaneously. Hundreds and thousands of measurements can be obtained at various depths over a wide area. The measurements can provide an accurate estimation of the extent of a radioactive plume within the soil sediments. 




GM Uranium probes have uses in applications where nuclear disaster has occurred and remote measurements are needed. GM Probes are available with long cables that allow operators to remain at a safe distance from high levels of radiation. Custom cable lengths are available to fit every need.




Nuclear radiation cannot be detected by humans. We know that radioactivity is everywhere around us. It is naturally occurring. Because radioactive elements are naturally occurring, they are being discovered in populated areas. As a practical matter, most radiation occurs at relatively low levels. The only way to know what the radiation levels are where you live is to conduct a “Home Survey”. Radiation detectors in the form of hand-held survey meters are available from companies like Ludlum Instruments. New and used survey meters can be purchased on line.
