Cosmic rays, i.e., protons and atomic nuclei with high energy from astrophysical origin, are the dominant producers of enhanced radiation doses at aircraft altitudes. While the assessment of dose rates produced by the permanent galactic cosmic ray (GCR) component is well-established and operational, the evaluation of the sporadic solar cosmic ray (SCR) contribution during so-called Ground-Level Enhancements (GLEs) is an issue of current research. Several institutions developed codes for the assessment of solar radiation doses at flight altitudes.

Under the coordination of Seibersdorf Laboratories (Dr. Peter Beck), EURADOS Working Group WG11 conducted a study comparing routine doses and dose rates at flight altitudes during two selected GLEs calculated using nine computer codes.

The results will be reported and discussed in a webinar on April 19, 2023, 14:00. The link for free registration to the webinar: https://eurados.sckcen.be/events-overview/19th-eurados-webinar-calculation-radiation-exposure-aviation-altitudes-case-solar-particle-events
