01
Radiological site characterisation
Baseline mapping before development or handover on contentious land.
Specialised Radiological Surveys
Non-contact aerial detection and mapping of radiological conditions, run through a formal academic sensor programme and validated before anything reaches a regulator.
Our radiological capability is built on a formal memorandum of understanding with the University of Bristol sensor programme: specialised detector payloads, flown and operated by StrataVance, with academic analysis validating every reading before a result is issued.
Flown swaths record natural and anomalous radiation across a site, separating geology-driven background from genuine anomalies. That distinction — between natural variation and something worth investigating — is exactly the interpretation a desktop exercise cannot deliver.
Count-rate and dose maps are delivered with full method statements, uncertainty and validation notes, so the output stands up to scrutiny in front of clients, landowners and regulators.
Division 04
Method
How a radiological campaign runs
-
Survey scoping & safety case
Site history, permissions and flight safety case agreed; detector configuration set.
-
Acquisition
Swath lines flown with altitude, speed and count-rate quality control in real time.
-
Processing & academic validation
Readings corrected, mapped and validated through the University of Bristol programme.
-
Delivery & interpretation
Dose, count-rate and anomaly maps issued with method statement.
Deliverables
Working outputs
Detection you can defend, not numbers in isolation.
- Count-rate and dose maps over the surveyed area
- Anomaly classification against geological background
- Contamination tracking and delineation
- Validation note from the academic programme
- Full method statement & uncertainty reporting
- GIS-ready raster and vector layers
