Model 960 Radiation Monitoring System

A high-sensitivity fixed monitoring system that detects, analyzes, and locates unwanted radioisotopes regardless of varying background. The Model 960 pairs a large lead-shielded plastic scintillation detector with a panel PC and a background-averaging algorithm to deliver near 100 percent detection probability for waste management, incineration, conveyor, and perimeter installations.

Verification notes. All specifications on this page are taken verbatim from the official Berkeley Nucleonics Model 960 datasheet PDF, dated 1/23/20. At capture time the live model-960 product page was serving real-time spectrum analyzer content, not radiation-monitoring content, so the live page was not used as a source. The Model 960 has no standalone hosted product image, so the hero and figures use labeled placeholders that describe the intended system photo. Confirm the live page slug, the energy and dose rate ranges, the operating temperature, the IP rating, and the web-copy variants (Pedestrian, H) and Central Command networking option before publishing.

1Overview

The Model 960 Radiation Monitoring System answers the growing need for radiometric control in waste management and incineration facilities. It is a high-sensitivity monitor built to locate unwanted radioisotopes regardless of varying background, the kind of contamination that carries radiological, economic, and legal risk. The Model 960 is optimized to fit anywhere in a facility.

Inside its discrete form factor sits a large plastic scintillation detector, counting electronics, and a background-averaging algorithm that drives near 100 percent detection probability. The system includes an alarm beacon and a panel PC for control, and it is available in dual configurations set to match a given site.

2Key Features

  • X and gamma radiation monitoring
  • Real-time data acquisition
  • In a 100 nSv/h background, detects radiometric anomalies of 16 nSv/h
  • Sturdy plastic scintillation detector in a robust housing
  • Background shielding of 10 mm Pb
  • Sensitivity of 150 kcps per µSv/h
  • Near 100 percent detection probability
  • Local or remote sound and light alarm

3Detector & Performance

The Model 960 is a fixed, installed area-monitoring system, not a handheld. A large plastic scintillation detector, available as a 25-liter large box or a 5-liter small box, is paired with a preamplifier, high-voltage supply, and data acquisition electronics. Each detector is shielded by 1 cm of lead. The shielding serves two purposes: it screens out background and it raises measurement efficiency through some backscattering.

Even in standby, the system stays in background mode and recomputes a new background average. Each second, the background is recalculated as the average of the last 5 minutes. Selective presence sensors then stop background updates and start a measurement when an object passes, whether a person, a trolley, or a vehicle. That prevents nuisance alarms from unrelated passers-by. The operator can select the alarm threshold, and the system raises a sound and light alarm when the threshold is exceeded.

The averaging time is programmable and is factory set to 300 seconds. When the proximity sensors signal an object, the Model 960 enters measurement mode and applies a programmable "measurement with object" threshold. The display shows the live count rate versus time in black, the average in light green, and the alarm threshold as a red line. This dual-threshold mode balances sensitivity against false alarms. Where sensors are expected to be engaged continuously, such as a conveyor belt or a crowded area, both thresholds can be set to the same level.

7Ordering / In the Box

A Model 960 installation pairs one control unit with the chosen detector configuration. The control unit measures 500 x 200 x 400 mm at 22.05 lb, runs on 110 to 220 VAC, and connects to the detector unit through a 10 m cable. Select the 25-liter large detector for maximum sensitivity and lead shielding, or the 5-liter small detector for tighter spaces. Add proximity sensors and a camera as the site requires, and network the system to a Central Command for an area-wide view.
