Model SAM 935 Portable Gamma Spectroscopy System

What the Health Physicists and Radiation Safety professionals say:

Better, Faster, Cheaper


The speed and accuracy of the SAM readings allowed us to complete tasks in 4 weeks instead of the usual 6 to 8 weeks


Because of the speed of detection and identification by the SAM, the process times were reduced by 80% resulting in significant cost savings in overtime pay.

...US Nuclear Power Plant

We selected the SAM because each reference we checked said it really does do what BNC says it will do. While other systems were too slow, very sensitive to background, and quickly confused when more than one isotope was present.

...Canadian Utility

The Model 935 from BNC offers significant cost savings over other technologies, is the fastest and most accurate NaI system available and reduces exposure times.

  • How to use the SAM 935

  • The SAM is accurate and does 75% of what our germanium systems will do, without the need to transport any heavy support equipment.

    ...US EPA

    The SAM pays for itself after 66 samples.
