The Earth's atmosphere and magnetic field protects us from a hostile space radiation environment:
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.
Radiation levels at altitudes used by commercial aircraft are greater than at sea level due to cosmic rays, and aircrew are classified as radiation workers in some countries. 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.
Assessing cosmic radiation exposures of aircrew is complex and can disrupt business processes such as rostering and record keeping due to the need for external consultants.
Our web API connects your existing software, whether crew management, flight planning, SaaS platform, or mobile app, to a validated model of cosmic radiation in the atmosphere using standard interfaces.
Rather than waiting hours or days for aviation dose calculations, and exchanging data files with third parties, your software can assess exposures automatically in a matter of seconds.
We offer a 14 day free trial with ongoing subscriptions starting from $200 per month and supported by a Service Level Agreement.
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.
