AERB Consultation & Licensing Support

AERB approval is not a form filled in after the room is built. It depends on decisions taken at design stage — shielding thickness, door specification, layout and access control. Get those wrong and the fix happens after the walls are already up.

Where AERB requirements actually enter a project

Owners often treat AERB as a final sign-off step, something to deal with once the room exists. By then every expensive decision has already been taken. Shielding calculations, room layout and access control need to be compliant from the first drawing, because each of them is embedded in the construction itself.

Retrofitting shielding into a finished room means opening up walls that were already signed off, redoing finishes, and delaying the equipment installation that everything else is waiting on.

Documentation we coordinate

  • Shielding design reports — calculations for the specific modality, workload and the occupancy of surrounding spaces
  • Layout plan documentation showing controlled areas and access control
  • Post-installation radiation survey and leakage certification, with recorded values handed over
  • Coordination across modalities — CT, cathlab, PET-CT and nuclear medicine, and MRI where the shielding is RF rather than radiation but is coordinated the same way
  • Support to your Radiological Safety Officer through the process

Built in, not bolted on

Because our own teams build the shielding and the lead doors, the certification survey happens against work we are directly accountable for. There is no third-party vendor finish to chase for compliance, and no argument about whose scope the failure sits in when a survey comes back short.

The common failure we are called in to fix: a room that passed its shielding design review but fails the post-installation survey, because the door was built by a joiner and leaks at the frame. The calculation was right. The construction was not. See lead lined doors.

What we do, and what stays with you

We coordinate the technical documentation AERB requires as part of an application — shielding design, layout and certification. The licence itself is held by the facility, and your Radiological Safety Officer remains the responsible person. Confirm the exact filing scope with us for your project, because it varies by modality and by the category of licence being applied for.

AERB, answered.

Do you file AERB applications on our behalf?
We coordinate the technical documentation — shielding design, layout and certification — that AERB requires as part of the application. The licence is held by the facility and your Radiological Safety Officer remains the responsible person. Confirm the specific filing scope with us for your project and licence category.
How early should AERB requirements be considered?
At design stage, before shielding is built. Retrofitting shielding after construction is significantly more expensive and disruptive than designing it in from the start, and it delays the equipment installation everything else depends on.
Our room failed its radiation survey. What now?
We survey to locate the actual leakage path rather than assuming — commonly the door, the frame, or a service penetration through a shielded wall — then remediate and re-survey to certify.
Does an MRI need AERB radiation approval?
MRI does not use ionising radiation, so radiation shielding requirements do not apply in the same way. It has its own siting and safety considerations around the magnetic field and RF shielding, which we coordinate as part of room planning.
