Aerospace Radiation Safety: A Regulatory and Scientific Gap.

As cruising latitude rises, Earth's magnetic field weakens, providing a thin atmosphere and less cosmic radiation shielding. Generally, commercial airlines cruise between 25,000 and 41,000 ft with the radiation dose rate fluctuating between 2 and 12 µSv/h based on the cruising latitude and solar particle events (SPE). Among all the cruising routes, polar and transpolar routes experience the maximum radiation exposure, which can exceed 80 µSv/h during the SPE at high latitude. For better understanding, if we compare it to chest X-rays using a real-world example, a one-way May 2024 flight from San Francisco to Paris recorded a radiation dose rate equivalent to four chest X-rays during the Gannon solar storm.

Why is it so crucial? Typically, an aviation crew logs 800 to 1,000 flight hours a year, resulting in longer repetitive radiation exposure, which can damage DNA sequences, leading to higher long-term cancer risks.

Beyond aviation, with ISS retirement in 2030, there is a greater likelihood of crewed missions extending into cislunar space, leading to a significant increase in cosmic radiation exposure. Despite the awareness of the health risks of prolonged radiation exposure, international standards lack a framework to harmonize safety standards for flight and space crew. Closing this regulatory gap is essential to protecting the people who fly our skies and explore our solar system.

  • Aviation: elevated incidence of breast cancer, melanoma, and reproductive risks documented in long-tenured flight crews.
  • Spaceflight: scarce human data; cislunar crews face GCR and SPE exposures with no agency-binding limits.
  • Regulation: EU EURATOM and ICAO frameworks exist for aviation, but coverage is uneven, and dose monitoring is inconsistent.

The Necessity of Internationally Harmonized Crew Radiation Safety Standards and Regulations.

Our paper at the 77th International Astronautical Congress argues that the absence of binding international safety standards is becoming a meaningful risk for cislunar missions. The research includes reviewing existing regulations, conducting a gap analysis, and drawing on longitudinal datasets from nuclear workers and the Hibakusha survivor cohort to propose concrete recommendations for harmonized crew safety standards, with particular emphasis on deep space exploration.
