Radiation contamination is becoming more of an issue in industry today. Responsibility and disposal of contaminated products is costly. Other issues with radiation contamination are:

  • Liability and safety issues
  • Process shut downs/loss revenue
  • Regulatory compliance issues

Kanawha Scales & Systems offers radiation monitoring with the following options and benefits:

  • Automated detection – Highest detection probability and fewest false alarms
  • Radiation source identification – Superior Detection technology to prevent contamination to your plant, your product and your personnel.
  • Integrate with vehicle weighing and material handling – detect 100% of your vehicles as they pass over your truck or rail scale or beneath your grapple while handling/ sorting your materials
  • Integrated documentation and traceability – Completely networkable systems allow for access and controls with full date data logging.

The radiation detection process of characterization is a four stage process:

Reduction of electronic “noise”
The front-end of Radcomm’s electronic circuitry has been kept to an absolute minimum thus significantly decreasing the introduction of electric noise to the system.

Every pulse is analyzed
The second stage of Radcomm’s electronics utilizes advanced signal discrimination with a zero lower level discriminator. This means every pulse is analyzed. These signals are cleared of electronic noise, random fluctuations associated with noise and shaped for the third stage.

Differentiation of random events from coincidental occurrences
Stage three then utilizes hardware and software pulse discrimination techniques that differentiate random events from coincidental occurrences in the incoming pulses from the scintillator. After this stage the pulses are processed with characterization hardware/software.

Background correction
In the final characterization stage the pulses from the scintillation material produced and the ambient background radiation are analyzed on a continuous basis to create a reference characterization. Background correction is performed automatically every sample period. This technique of background correction is extremely important especially when ambient background radiation level is high, when there are large atmospheric changes and when the contents of a shipping container vary in density. This allows the setting of extremely low alarm thresholds and minimizes the impact of false alarms.
