Which radiation model does the API use?

The Aviation Radiation API uses the FAA's CARI-7 model to estimate cosmic-ray induced ionizing radiation in the atmosphere for points and flight paths.

What outputs does the API provide?

The API returns effective dose rate (µSv/h) for flight routes.

Can the API compute dose along complete flight routes with step-climbs?

Yes. You can submit great-circle routes via waypoints or ICAO airport codes, including altitudes and step-climb profiles, and the API will compute cumulative doses.

What standards or guidance does this support?

Outputs follow effective dose conventions consistent with ICRP guidance and can support aircrew exposure monitoring programs aligned with aviation regulator recommendations.

What are typical use cases?

Pre-flight planning, operational monitoring of aircrew radiation exposure, EFB and dispatch integrations, and compliance reporting workflows.

the hazard to aircrew

Space radiation collides with gases in the atmosphere, leading to a complex shower of high energy radiation. Excessive exposure to radiation can damage DNA and lead to long-term health effects such as an increased risk of cancer. Due to elevated radiation levels, aircrew are classified as radiation workers in some jurisdictions. Assessing cosmic radiation exposure of aircrew is complex and can disrupt business processes such as rostering and record keeping if external consultants are needed.

helping with regulatory compliance

In Europe, Section OPS 1.390 of the European Union COMMISSION REGULATION (EC) No 859/2008 and Council Directive 96/29/Euratom outlines the standards for the protection of workers from ionizing radiation exposures. Assessments are a regulatory requirement.

In South Korea, the Living Environment Radiation Control Act includes obligations for airlines to record, store, and report radiation exposure data and includes penalty provisions for violations of the Act.

Our Route Dose Web API connects enterprise software, whether crew management systems, flight-planning tools, SaaS platforms, or mobile apps, to a validated model of cosmic radiation in the atmosphere using standard interfaces. Subscriptions start from $240 per month and are covered by a Service Level Agreement.

solar corrections

antarctic measurements improve accuracy

The interplanetary magnetic field is a result of the solar wind produced by our Sun. The Heliocentric Potential (HP) describes the level of shielding that the interplanetary magnetic field provides us from galactic cosmic rays. The greater the HP value, the lower the radiation dose at the same altitude. The HP value is modulated by the solar cycle.

Neutron monitoring stations tell us how much residual cosmic radiation there is at ground level. High latitude stations (e.g. Antarctica) provide the clearest picture due to the minimal geomagnetic shielding.

Our Aviation Radiation API uses official HP values from the US FAA. We predict our own values to ensure dose calculations can be made for today's date (in case of delayed release of official values). Our automated data management system fetches real-time neutron monitor data from the Australian Antarctic Division and feeds that into a machine-learning pipeline that predicts current HP values.

The figure to the right shows the official and predicted HP values that we use in our radiation calculations.

scientific validation

We validate the API and underlying models against published experimental data and benchmarked against other codes.

Results were presented at the 5th International Symposium on the System of Radiological Protection (ICRP2019).
