Sealed Radioactive Source Removal & Recycling – Radiation Detection

Radioactive Sealed Source Removal Service

IRAC Asia provides a comprehensive, technically compliant service for the removal, packaging, transport, and transfer of both active and disused or end-of-life radioactive sealed sources in on-site or industrial applications such as radiography, gauging, and process control.

IRAC Asia service covers the full lifecycle of source decommissioning and transfer, including:

SCOPE OF WORK

Source Extraction and Handling
- On-site removal of sealed radioactive sources from operational, redundant, or decommissioned devices.
- All extraction procedures are performed by trained radiation protection personnel in accordance with ALARA (As Low As Reasonably Achievable) principles.
Packaging and Shielding
- Preparation and containment of the source in certified Type A or Type B transport containers in accordance with IAEA Safety Standards and ADR/RID/IMDG Class 7 transport requirements.
- Packaging configuration based on source activity, isotopic composition, and dose rate measurements.
Transportation Logistics
- Secure transfer of the packaged source from the installation site (onshore or offshore) to a licensed long-term storage, recycling, or final disposal facility.
- Compliance with all applicable transport regulations (IAEA SSR-6, ICAO, IMO, and national competent authority guidelines).
Transfer of Legal Custody
- Formal handover of the radioactive material to a receiving facility authorised under local and international regulatory frameworks (e.g., possessing a valid Radioactive Material Handling Permit).
- Full documentation provided for regulatory reporting and audit purposes.

Benefits

Eliminates the need for multi-vendor coordination.
Ensures full regulatory and safety compliance throughout the removal process.
Reduces administrative and technical burden on the licensee.
Guarantees traceability and chain-of-custody documentation.
Supports end-of-life source disposition planning under national waste management policies.

Regulatory Compliance

The service is conducted under strict adherence to the following standards and regulations:

IAEA Safety Standards Series (GSR Part 3, SSR-6)
ADR/RID/IMDG/ICAO/IATA Dangerous Goods Transport Regulations (Class 7)
Local radiation protection and waste disposal regulations
ISO 2919 and ISO 9978 (source classification and leakage testing)

RADIATION Shielding Integrity Testing

IRAC Asia offers comprehensive pre-operational and post-installation shielding verification services to proactively identify deficiencies before source deployment, thereby reducing remediation costs, project delays, and radiation safety risks.

IRAC Asia has extensive experience in the testing and evaluation of shielding systems for a wide range of ionising radiation applications, including but not limited to:

CAPABILITIES

Industrial & Calibration Facilities
- Industrial radiography enclosures
- Gamma and X-ray calibration facilities
- NDT (Non-Destructive Testing) bunkers
Laboratory & Operational Equipment
- Hot cells and shielded gloveboxes
- Shielded workstations
- Transport and storage containers with built-in shielding

Testing Methodologies

Our shielding integrity assessments include:

Radiation Leakage Mapping using calibrated survey meters and dosimeters
Monte Carlo Modelling and Dose Rate Prediction (where design data is available)
Gamma and X-ray Penetration Testing using controlled sources (e.g., Cs-137, Co-60)
Gap Analysis and Void Detection through structural scans and shielding material verification
Compliance Testing against shielding design criteria based on national and international standards (e.g., NCRP, IAEA, ISO)

Benefits of Early Shielding Verification

Ensures shielding performance prior to radioactive source commissioning
Reduces the likelihood of regulatory non-compliance and costly retrofitting
Enhances facility safety during commissioning and operation
Supports licensing and facility registration with radiation protection authorities
