40TGU-1000 – Triple Gamma
Description
The 40TGU-1000 Triple Gamma Geiger probe was designed specifically for use in Uranium Exploration and Production. It measures natural gamma radiation from a Sodium Iodide scintillation crystal and a ZP1320 High-flux Geiger-Muller tube pair. This results in three natural gamma logs collected simultaneously. The G-M tube pair, installed below the NaI detector, has been used successfully to determine ore grade in very high concentrations of U3O8. By having three different detector sensitivities, the 40TGU-1000 probe can be used in exploration and production projects with wide variations in ore grade. Accurate concentrations can be measured in uranium ore grades ranging from less than 0.1% to 20%.
