In-Flight Crew Radiation Exposure

Welcome to the Human Spaceflight - In-flight crew radiation exposure service

Overview

The service “Human Spaceflight: In-flight crew radiation exposure” aims to provide information which can be used to help estimate in-flight radiation doses. Radiation environments considered include Earth’s radiation belts, galactic cosmic rays, and solar energetic particles. This service is made possible by providing measurements and estimates of current local area radiation fluxes combined with spacecraft and human phantom shielding geometry models, as well as onboard passive or active dosimeter data (e.g. thermoluminescent dosimeters [TLDs], tissue equivalent proportional counters [TEPCs]). The service is intended for personnel involved in monitoring the radiation environment during crewed space missions.

This service is implemented through a combination of products, tools and alerts which can be found through the sections below along with expert support provided by the teams constituting the ESA Space Weather Service Network. Should you require further guidance in the use of this service, or have specific questions about any aspects of the service presented here, don’t hesitate to contact the Helpdesk.

User Manual

Particle radiation in the form of Solar Energetic Particles and Galactic Cosmic Rays is considered the main hazard for human spaceflight, specifically when considering a potential return trip to the Moon or interplanetary travel in general. Even at Low Earth Orbit (LEO) like the International Space Station, particle radiation poses a risk as energetic particles can penetrate deep into the magnetosphere, in particular in the polar regions. Furthermore, spacecraft passing the Van Allen radiation belts need to take into account the increased radiation levels in these regions. Monitoring the space environment in (near-) real-time to evaluate the possible health effects of space particle radiation on humans is therefore necessary. This includes space environment data (e.g. particle radiation, solar X-ray and UV observations) and dose measurements.
