QL 40 LOGGING TOOLS

Gamma Surveyor is a group of multi-channel gamma-ray spectrometers designed for measurements of natural and artificial radioisotopes in ground, boreholes and laboratories.

This group of instruments covers a wide range of devices using various probes and types of detectors:

• portable gamma-ray spectrometer for surface and borehole measurements
• handheld gamma-ray spectrometer
• compact version of the handheld gamma-ray spectrometer
• accurate handheld radiameter
• carborne spectrometer with high volume detector
• laboratory spectrometer with special detectors and features

Gamma Surveyor offers three basic measuring modes:

• Spectra & Assay – spectral measurements with determination of K, eU, eTh concentrations
• Dose rate – precise radiometric measurements
• Search – quick and selective search for gamma-ray sources (0.5 s response time)

The measuring system supports point, profile and continuous measurements as well as the use of external GPS data.
