RadComm
Systems: The Future of Radiation Detection for the Steel Industry. |
|
| >> Superior detector technology, coverage and applications |
|
 |
In
order to provide reliable and rugged state-of-the-art detectors suitable
for any hostile environment, Radcomm uses nothing but lab-quality
components, such as premium grade PVT and components using low noise
design technology. Offering
the largest detector coverage available today at 68” vertical
and 31” wide, Radcomm’s RC4138 two detector truck system
provides premium top to bottom coverage, without sacrificing dwell
time. Similarly, the Cricket grapple mounted system comes in four
detector sizes, engineered to fit most grapples used in the steel
industry today. Each
of Radcomm’s conveyor and charge bucket detector applications
are designed and engineered to fit customer specific applications. |

Highest detection probability and fewest false alarms |
|
| Radcomm
engineers have developed proprietary technology that not only tracks
the pulse count rates from the PVT scintillator but applies a special
characterization analysis on each pulse. The key benefit of this
“characterization” is the knowledge that specific isotopes
will produce predictable results.
Characterization is used to eliminate any major fluctuations caused by varying densities in loads of scrap metal, along with any atmospheric changes that might affect a reading. This technique is similar to what is utilized in gamma ray spectroscopy where a sodium iodide scintillator is used. Characterization is a signal processing technique that focuses on real-time system noise cancellation, correction of ambient background variations and maintaining extremely accurate alarm threshold settings, all resulting in higher radiation detection sensitivity and the fewest false alarms. |

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. |
