Decommissioning & Disposal of X-ray Generating Analytical Instruments
RADXION was contracted by a leading research institution to decommission, remove, and responsibly dispose of end-of-life X-ray analytical instruments (e.g., XRF spectrometers, XRD diffractometers, and micro-CT scanners). These devices contain regulated components—X-ray tubes, high-voltage generators, lead shielding, and electronic waste—that require specialized handling to protect personnel and the environment.
Objectives
Safe Decommissioning
Power-down, disassemble, and physically isolate all X-ray sources and high-voltage assemblies.
Regulatory Compliance
Ensure all radioactive-equivalent and hazardous materials are handled per IAEA SSR-6, local radiation safety, and electronic-waste regulations.
Environmental Stewardship
Facilitate recycling of metals and recovery of valuable components wherever feasible.
Full Documentation
Provide auditable records from equipment removal through final waste disposal or recycling.
Scope of Work
Phase 1Pre-Decommission Survey
- Identify all devices and map their locations.
- Verify operational status and any residual activation or contamination.
Phase 2Device Decommissioning & Disassembly
- Disconnect power, bleed high-voltage capacitors, and lock-out/tag-out electrical circuits.
- Remove X-ray tubes and cushion in lead-lined transport cases.
- Dismantle internal lead shielding panels and transport to licensed radiological recycling facility.
- Segregate circuit boards, cables, and non-shielded metal frames for e-waste recycling.
Phase 3Packaging & Conditioning of Hazardous Components
- Encapsulate X-ray tubes in Type A packaging with shock-absorbent inserts.
- Bag and box lead shielding elements with hazardous-waste labeling.
- Collect high-voltage capacitors and any mercury-containing switches as universal hazardous waste.
Phase 4Regulatory Approvals & Transport
- Prepare waste manifest and transport documentation compliant with ADR/RID and local environmental authority.
- Coordinate with FANR (if any sealed sources or activation products are present) for transport licenses.
- Engage a licensed carrier for both radioactive-equivalent and electronic hazardous components.
Equipment & Materials
| Transport Containers | Lead-lined X-ray tube cases; UN-approved drums for capacitors and mercury devices. |
|---|---|
| Handling Tools | Remote grippers for hot components, torque-limited tools, and shielded transfer trolleys. |
| Monitoring Instruments | Portable survey meters (for any residual X-ray leakage), high-voltage tester, and contamination swipe kits. |
Regulatory & Safety Compliance
Radiation Safety
IAEA SSR-6 guidelines applied to disused X-ray tubes considered “radiation sources.”
Electrical Safety
Lock-out/tag-out per IEC 60364 and local electrical codes.
Hazardous Waste
Hazardous chemical and e-waste regulations for capacitors, PCBs, and mercury switches.
Transport
ADR/RID for road transport; FANR licensing if any sealed-source equivalency is identified.
