Corela GRG-01
Key features
- Corela GRG-01 includes an array of novel compact and high sensitivity radiation detectors embedded in efficient shielding and in a close contact with the measured sample (core). Its design minimizes the requirement for shielding size and weight while achieving the accuracy and precision of larger conventional setups.
- The revolutionary modular architecture can combine a series of standardized instrumented segments to perform simultaneous measurements along core samples and provide customizable statistical precision.
EASY FIELD DEPLOYMENTCorela GRG-01 is intended for direct field deployment enabling conduction of K-U-Th analyses directly on site of the drilling or in adjacent coreshacks. Unlike large NaI:Tl-based laboratory set-ups, Corela GRG-01 can be deployed on site by a small van or a helicopter. |
PRECISE AND FASTNext generation novel compact and high-sensitivity radiation detectors with FWHM resolution similar to NaI(Tl) but featuring double the density and sensitivity. Up to 40 m of total depth measured per |
MODULARPerfect modularity to suit your needs. You can choose up to 7 measuring segments for highest productivity or different set-up for slower but cost-efficient solutions. |
PRODUCTIVEIt takes only a short time to set Corela GRG-01 ready for operation. High flexibilty in optimalization of the measuring process – Total measurement time versus precission and profile resolution of the core |
Corela GRG-01 is a joint product with
