SHORT ANSWER

How do you choose a security X-ray scanner curtain?

Selecting a curtain for a baggage or parcel X-ray scanner means matching the series voltage range, lead equivalence, hanging weight, surface wear and strip geometry. The Radbar catalog lists three lead-free series: BaseShield (≤160 kV, cost-effective), ProShield (≤120 kV, general-purpose) and UltraShield (≤160 kV, lightweight), weighing 7–8, 6.3–6.6 and 4.3–4.5 kg/m² at 0.35 mmPb. Listed grades are 0.35 / 0.5 / 0.6 / 1.0 mmPb, with customization from 0.125 to 2.0 mmPb.

Curtains in a baggage scanner tunnel

  1. X-ray source and tunnel; choose a series whose listed range (≤120 or ≤160 kV) covers the scanner.
  2. Entry and exit curtain sets, supplied as rolls, pre-cut sets or single strips.
  3. Overlap and strip width must match the original hanger and hole pattern.
  4. Bags push the strips aside; hanging weight affects passage and return.
  5. Flow direction; VBK film or FBK fabric surface is chosen by wear pattern.

  • Surface options: high-wear VBK film or FBK fabric coating.
  • Maximum listed width 1200 mm; temperature range −40 to 70 °C.
  • Supply as large roll, pre-cut set or single strip, with custom printing.

SELECTION STEPS

Make the decision in order.

  1. 01

    Match the voltage range

    Confirm the scanner operating voltage and choose a series whose listed range covers it.

  2. 02

    Set lead equivalence and method

    State the required grade together with its test conditions.

  3. 03

    Balance weight and return

    Lighter strips help passage, but return motion and overlap still need checking.

  4. 04

    Choose the surface

    VBK or FBK, based on wear pattern, contact conditions and maintenance.

  5. 05

    Send the drawings

    Opening size, hanger details, strip length, overlap and replacement-part drawings; choose roll, set or strip supply.

COMMON MISTAKES

Where specifications usually go wrong.

  • Defaulting to the lightest series. The lightest option is not automatically right for every machine.
  • Treating “over 5 million baggage passes” as a service-life guarantee without checking load and criteria.
  • Replacing strips without matching the original overlap and hole pattern.

FAQ / FREQUENTLY ASKED QUESTIONS

Questions worth asking.

What determines the correct scanner curtain?

Match the series voltage range, lead equivalence, hanging weight, tunnel opening, surface and strip geometry. The lightest option is not automatically appropriate for every machine.

Can replacement strips be made to an OEM drawing?

The catalog lists pre-cut sets and individual strips. Provide mounting holes, strip length and width, overlap, surface requirements and the scanner operating range for confirmation.
