When an employee, insurer, regulator or legal team asks how exposure was assessed, a total dose alone may not answer the question. Missing flight records or undocumented assumptions can make a historical assessment difficult to explain or reproduce.

Can your records show:

• Which flights the crew member operated?
• Which radiation model and input data were used?
• What exposure was estimated at the time?
• Whether trajectories were recorded or assumed?
• How unusual solar events were considered?
• How an independent reviewer could reproduce the assessment?

Give safety, occupational health and risk teams the evidence behind the estimate, with gaps and limitations made explicit.

Exposure obligations vary by jurisdiction. Reproducible records help organisations explain how exposure was assessed and support their applicable reporting processes.

In the European Union, Council Directive 2013/59/Euratom sets the radiation-protection framework, including provisions for aircrew exposure to cosmic radiation. National implementation determines the requirements applicable to an operator.

In South Korea, the Act on Protective Action Guidelines against Radiation in the Natural Environment addresses cosmic-radiation safety for aircrew, including exposure assessment and records.

Scope your assessment against the requirements that apply to your organisation. An exposure review supports that process; it is not a certification of legal compliance.

Start with an independent assessment of your existing radiation exposure process and records. Agree a defined scope and fixed fee before work begins.

• Review a representative sample of historical crew exposure.
• Independently recalculate selected flights using available data.
• Compare estimates with your existing exposure records.
• Identify missing data and assumptions that cannot be reproduced.
• Assess record quality, traceability and retention practices.
• Recommend practical controls and opportunities for automation.

Receive a comparison of sampled results, documented assumptions and limitations, and prioritised recommendations. The review provides a starting point for improvement without a platform commitment.

Discuss an exposure review

Turn review findings into a repeatable recording process. Integrate automated flight-dose calculations with your crew and operational systems to support cumulative exposure histories, periodic statements and audit reporting.

Link flight estimates to the crew who operated them, and retain the calculation inputs, model details and assumptions needed for later review. We can scope the integration, record ownership and retention requirements with your team.

Planned-route estimates support pre-flight assessment; recorded trajectories support post-flight reconstruction. Keep the basis of each estimate visible in your records.

Reconstruct exposure from recorded aircraft trajectories, using the flight's observed altitude, location and timing rather than relying solely on planned routes or generic assumptions.

Our satellite-based ADS-B integration evaluates dose rates along recorded waypoints and integrates them across the flight. Results include total estimated effective dose and timestamped waypoints with altitude and dose-rate values.

Historical reconstruction depends on available track and model data. We assess coverage and document gaps or substituted assumptions as part of the review.

The Aviation Radiation API supplies calculations for your existing crew, safety and operational software.

Flight tracks, routes and points

• flighttrack: estimate dose from recorded ADS-B trajectories using an aircraft ICAO 24-bit address and UTC departure date.
• route: estimate planned-route dose along airport-to-airport or coordinate-defined great-circle paths, with optional step-climb.
• point: calculate dose rates at individual locations for integration with operational systems.

Radiation models

CARI7, from the FAA Civil Aerospace Medical Institute, supports routine flight-dose estimation. NASA's NAIRAS model supports hourly nowcast monitoring and solar energetic particle event awareness.
