4. Scanning system employing radiation source instead of X-ray generator is not acceptable. Rationale: X-ray generator does not emit X-ray unless it is being energized. However, a system with radiation source has got finite probability to emit radiation if there is leakage in the relevant shielding. A system employing radiation source has got higher risk to the public than the X-ray system.

5. Penetration capability: at least 300mm steel.

Penetration capability is a performance indicator. A scanning system with higher penetration capability can reveal more details of object(s) during inspection.
