Gamma Sensors

GE Oil & Gas tailors every scintillation detector to your exact specifications. We provide a broad range of detector configurations, including virtually any crystal size, mounting and interface adaptations, as well as built-in radioactive check sources.

The assembly’s high-strength sapphire window, combined with a patented optical coupler, allows for maximum light output. Using the highest quality materials and a cutting-edge design, GE is committed to engineering its sensors to meet strict customer specifications.

Delivering one of the industry’s highest sensitivities, our gamma sensors provide geologists and drilling contractors with the precise measurements required for accurate formation location and identification.

Our radial suspension system also contributes to greater detector sensitivity. By minimizing the radial space needed to isolate the crystal from vibration, larger crystals can be packaged inside the sensor housing. Higher sensitivity can help customers log faster or reduce the size of the detectors for more compact tools and thinner bed resolution. Thin wall titanium housings minimize gamma attenuation for better gamma radiation transmission at lower energies. These features allow customers to operate downhole confidently,even in the most severe conditions.
