Portable X-ray systems provide critical field inspection capabilities for explosive ordnance disposal (EOD), border security, forensics, and industrial NDT where fixed equipment is impractical. Modern battery-operated digital systems weigh 15-30kg complete, offering 2-4 hour runtime with real-time wireless image transmission.

Operational Deployment
EOD Tactical Considerations
Safe Operating Distance
Bomb technicians operate portable X-ray remotely:
- Minimum Distance: 30 meters (radiation safety + blast protection)
- Remote Trigger: Cable or wireless activation
- Wireless Image: Real-time transmission to operator tablet
- Robot Integration: Systems mountable on EOD robots for placement
Typical EOD Setup
- Reconnaissance: Visual assessment of suspicious package
- Robot Deployment: Place X-ray generator and detector (optional)
- Manual Placement: Or technician places equipment at safe distance
- Withdrawal: Retire to safe distance (30m minimum)
- Exposure: Activate X-ray remotely, capture image
- Analysis: Review image for threat indicators (wires, batteries, timers)
- Decision: Render-safe, controlled detonation, or clear
Border Patrol Operations
- Mobile Checkpoints: Deploy at temporary roadblocks
- Vehicle Sweeps: Inspect doors, quarter panels, fuel tanks
- Cargo Containers: Spot-check specific items from shipments
- Rapid Deployment: 10-15 minute setup from vehicle transport
Industrial Field Radiography
Pipeline Weld Inspection
- Setup: Generator on one side of pipe, detector opposite
- Exposure Technique: Panoramic or double-wall technique
- Acceptance Criteria: API 1104 defect classification
- Documentation: Digital images stored with weld identification
- Radiation Safety: Exclusion zone established per state regulations
Radiation Safety and Compliance
Regulatory Requirements
State Licensing (U.S.)
- Radiographer License: State-issued certification required
- Equipment Registration: Annual registration with health department
- Training: 40-hour radiography course + exam
- Reciprocity: Some states recognize other state licenses
Safety Equipment

Exclusion Zone Calculation
Safe distance depends on X-ray energy and exposure time:

|---|---|
| 50-100 kVp | 3-5 meters |
| 100-160 kVp | 5-10 meters |
| 160-300 kVp | 10-20 meters |
Note: Actual exclusion zones calculated using inverse square law and measured with survey meter
