Portal monitor for excavation materials in boxes and containers
Portal monitor that measures the radioactivity level of excavation materials of various kinds. Two pairs of large plastic scintillators on the sides give a wide measurement area, and the open top makes it easy to place boxes and containers on the platform scale. The detector positions are set via PLC from the box’s standard dimensions, and the background is measured and subtracted automatically.

| Use | Measuring the radioactivity level of excavation materials of various kinds in boxes and containers1 |
|---|---|
| Detector type | Four plastic scintillators 100 × 50 × 5 cm2 |
| Active area | 5000 cm² per detector; two pairs mounted on the sides of the portal1 |
| Energy range | 35 keV–2 MeV2 |
| MDA | 5 Bq/g for ¹³⁷Cs (10 min)1 |
