Preventive Maintenance Services for Radiation Equipment

Why Preventive Maintenance Matters

If your facility operates self-contained (Category I) irradiators, gamma beam (Category II) irradiators, instrument calibrators, or X-ray based irradiators, preventive maintenance is essential for maintaining safe, reliable, and compliant operation.

ATOM SPEC preventive maintenance programs support:

• Regulatory Compliance
  Maintain readiness with documentation supporting NRC, Agreement State, and internal radiation safety program requirements.

  Equipment Reliability
  Identify wear, degradation, or performance concerns before they result in unexpected equipment failures or operational downtime.

  Operational Safety
  Verify critical safety systems, interlocks, indicators, controls, and operational functions that protect personnel and users.

  Inspection Readiness
  Maintain organized maintenance records, service documentation, and verification results to support audits and regulatory inspections.

  Lifecycle Management
  Evaluate aging irradiator systems, assess equipment condition, and support continued operation beyond original service expectations.

Preventive Maintenance Inspection Scope

ATOM SPEC performs comprehensive system evaluations to verify equipment condition, safety functions, and operational performance.

Typical inspection activities include:

• Safety systems to ensure safe operation

• Dose rate surveys to verify exposure limits

• Leak testing in accordance with NRC and state regulations

• Electrical system checks — tight connections, relay operability, software

• Switch integrity tests to ensure no critical failure in safety systems

• Timer calibration using certified timing tools

• Interlock system testing to verify safety shutoff mechanisms

• Mechanical inspection — cables, motors, chains, sprockets, and bearings

• Component lubrication and adjustment to prevent wear and failure

• Source movement checks and exposure rate measurements for operational accuracy

• Parts: replacement parts are OE or equivalent (similar - like for like)

Following completion of service, ATOM SPEC provides:

• Certificate of Preventive Maintenance

• Detailed service report documenting inspections performed, results, observations, and recommendations

• Corrective action recommendations, when applicable
