Overview
Radiographic testing uses X-ray or gamma radiation to produce high-resolution images of internal structural features with clarity exceeding GPR in heavily congested zones. The technique produces shadow images analogous to medical X-rays.
SiteOps deploys radiographic testing where GPR resolution is insufficient — typically in heavily reinforced connection zones, post-tensioning anchorages, and areas with multiple reinforcement layers.
Radiographic testing requires access to both sides of the element, radiation licensing, and exclusion zones. These constraints make it more complex than GPR, so SiteOps uses it selectively where additional resolution is justified.
All radiographic testing is performed by licensed operators in compliance with ARPANSA requirements.
Applications
Congested Reinforcement
Clear imaging in beam-column connections and complex junction details.
Post-Tensioning Assessment
Imaging tendons to detect wire breaks, corrosion, and grout voids.
Grouting Verification
Confirming complete grout fill in post-tensioning ducts.
Weld Inspection
Assessing weld quality in critical steel connections.

When is X-ray used instead of GPR?+
Only where GPR cannot provide sufficient resolution — heavily reinforced zones or post-tensioning tendon assessment.
