Conveyor-belt contamination monitor for small objects
Gamma monitor that measures the radioactivity of small objects, such as boxes, tools and laundry bags, while a conveyor belt carries them through a tunnel-shaped measurement area. Up to four shielded plastic scintillators surround the object, and photocells drive the measurement cycle automatically; uncontaminated objects move on while alarms are given visually and acoustically. The monitor stands on locking wheels.

The number after each value refers to the source listed below. Values are as published by the manufacturer; the exact configuration is always confirmed in our quotation.
| Detector type | Up to four plastic scintillators 40 × 40 × 5 cm: one at each side, one under the belt and one at the top2 |
|---|---|
| Detector spacing | Motorised upper detector; 8–80 cm between upper and lower detector2 |
| Software | Compares the measured background with the preset threshold, displays detector count rates and calculates activity in Bq or Bq/g2 |
|---|
| Use | Measuring the radioactivity of small objects – boxes, tools and laundry bags – carried through the measurement area by a conveyor belt1 |
|---|---|
| Lead shielding | Lead 10 mm on the external sides2 |
| MDA | 200 Bq for ⁶⁰Co (10 s)2 |
| Belt speed | 13 cm/s2 |
| Measurement sequence | Photocells track the object: its length is calculated, data are acquired for a preset time, results are shown and uncontaminated objects go to the end of the belt; long objects are scanned in consecutive steps; a static operator-guided mode is available1 |
| Construction | Frame on four locking wheels; belt cover resistant to cuts and chemical corrosion2 |
