(And the Exact Requirements You Should Know Before Installation)
When hospitals plan to install a fixed x ray machine, many problems don’t come from the equipment itself—but from room preparation mistakes. These errors lead to delays, extra construction costs, or even failure to pass radiation inspection.
Below is a practical, experience-based guide covering room size, shielding, doors, power supply, and real-world requirements—based on projects delivered across hospitals in Africa, the Middle East, and Southeast Asia.
One of the most common mistakes is underestimating space.
| X-ray Power | Suggested Room Size |
|---|---|
| 32–50 kW | ≥ 18–20 m² |
| 65–80 kW | ≥ 22–25 m² |
| 100 kW+ | ≥ 25–30 m² |
👉 This space includes:
Patient table movement
Tube stand travel
Detector positioning
Technician safe distance
Maintenance access
Common mistake:
Designing only for the machine footprint and ignoring operator movement and patient transfer space.
Many hospitals think adding lead sheets to one wall is enough. This is risky and often fails inspection.
(Exact thickness depends on local regulations, workload, and distance)
| Area | Recommended Lead Thickness |
|---|---|
| Main walls | 1.5 – 2.0 mm Pb |
| Control room window | 2.0 mm Pb glass |
| Doors | 1.5 – 2.0 mm Pb-lined |
| Door frame & gaps | Must be fully sealed |
⚠️ Critical mistake:
Ignoring door seams, window edges, and cable holes — radiation leakage is often detected here.
Even if walls are well-shielded, doors and observation windows can become the weak point.
Use lead-lined swing or sliding doors
Install lead glass observation window
Ensure overlapping lead at door edges
No exposed gaps between wall and frame
💡 Tip from real projects:
Radiation inspectors often check door handles, hinges, and corners first.
Many installation delays come from unstable power, not insufficient power.
| Item | Recommendation |
|---|---|
| Input voltage | 380V ±10% (3-phase) or 220V (single-phase) |
| Power capacity | ≥ 1.3–1.5× generator rated power |
| Grounding | Dedicated medical grounding |
| Voltage stability | Fluctuation ≤ ±5% |
⚠️ Common mistake:
Using shared power lines with elevators, HVAC, or CT scanners → causes exposure errors and generator alarms.
Operators should never be too close to the exposure area.
Separate control console room or shielded wall
Minimum 2–3 m distance from tube center
Clear line of sight via lead glass window
High-power X-ray machines generate heat.
Natural ventilation or exhaust fan recommended
Avoid sealing room completely without airflow
Especially important in hot-climate countries
Before delivery, hospitals should confirm:
✔ Room size meets requirement
✔ Lead shielding design approved
✔ Doors & windows lead-lined
✔ Stable power & grounding
✔ Control console position confirmed
At Fatali-Med, we provide:
Room layout drawings
Power requirement sheets
Online technical guidance during preparation
Remote installation & commissioning support
With 23 years of factory experience, we help hospitals avoid costly mistakes before equipment arrives.
A fixed X-ray system is a long-term investment. Getting the room wrong can cost more than the machine itself.
📩 Tell us your room size, country, and planned kW level —
we’ll review your layout and recommend the right X-ray machines configuration before you order.
👉 Reliable equipment starts with the right preparation.
