Increased Crew Radiation Exposure Risk
Welcome to the Human Spaceflight - Increased crew radiation exposure risk service
Overview
The service “Human Spaceflight: Increased crew radiation exposure risk” aims to provide information which can be used to help estimate the expected in-flight radiation dose. Radiation environments considered include solar energetic particles, galactic cosmic rays, and Earth’s radiation belts. This service is made possible by providing forecasts of local area radiation fluxes combined with spacecraft and human phantom shielding geometry models. The service is intended for personnel involved in monitoring the expected 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. Forecasting the space environment to evaluate the possible health effects of space particle radiation on humans is therefore necessary.
Near-Earth environment forecasts
Forecasts for solar proton events are provided by the COMESEP, HESPERIA and Alert/E products. The COMESEP Alert System delivers fully automated alerts for the risk of an SEP event with protons energies >10 MeV and >60 MeV following the obervation of a M- or X- class flare. HESPERIA REleASE uses near relativistic electron measurements to provide a forecast for 15.8-39.8 MeV and 28.2-50.1 MeV protons with a lead time of up to 90 minutes, while the HESPERIA UMASEP-500 scheme issues a >500 MeV SEP prediction based on a time lag-correlation of solar electromagnetic flux with the particle flux near Earth. Alert/E provides the probability for a solar radiation storm of protons with energies >10 MeV for the next 4 days and is updated twice daily by the forecaster of the Met Office Space Weather Operations Centre (MOSWOC). Forecasts for geomagnetic storms in terms of indices are provided by the UAH, IRF, ALert/E and FORIND products.Solar Activity forecasts and propagation through the heliosphere
Solar Flares forecasts are provided by automatic tools (A-Effort, Flarecast) and human forecasters (ROB/SIDC, UKMO). The CME propagation times are provided by DBEM and Enlil/E. To track CMEs, corotating streams and energetic particles in the heliosphere, the tool PROPTOOL can be used. The SIDC also provides a daily space weather bulletin. MoreInterruptions
