Free-release assay of large waste containers with up to four HPGe
Automated system that scans and characterises waste in bags, boxes, drums and B25 containers for free release. Up to four HPGe detectors on two movable towers measure the container in sub-sections while a heavy-duty platform moves it through the measurement area. The software reports activity, MDA and a release index per nuclide against customisable limits, and adds hard-to-measure nuclides via scaling factors.

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 electro- or nitrogen-cooled HPGe detectors on two movable towers (up to two each)1 |
|---|---|
| Detector positioning | Height set automatically with 1 mm resolution by container size; towers positioned manually at the recommended distance1 |
| Energy resolution at 1.33 MeV | HPGe: ≤2.3 keV FWHM for ⁶⁰Co (1332.5 keV)1 |
|---|---|
| Relative efficiency | 15–150% (nitrogen-cooled), 50–150% (electro-cooled)1 |
| Energy range | HPGe: 30 keV–7 MeV1 |
|---|
| Cooling | Stirling or nitrogen cooler; hardened cryostats that can be temperature cycled at any time and restart automatically after power loss1 |
|---|---|
| Load capacity | Containers up to 3 m³ (B-25 ISO), max. 3,000 kg; weighing system with 1 kg resolution1 |
| Software | Release index per nuclide against customisable limit tables; scaling factors add low or non-gamma-emitting nuclides; final report with hot spots1 |
|---|
