MissionDPT: Simulation and Forecasting of Radiation Doses and Health Risks for Space Exploration Missions

Radiation exposure in space presents significant challenges to crew health and performance. To mitigate its impacts, research in space radiation environment, mass shielding geometry, nuclear interactions, transport codes and biological responses has been conducted for decades, offering many established models and codes. In this work, a web tool MissionDPT (Mission Dose Projection Tool) is reported which incorporates the most up-to-date version of these codes with simple input and output interface, enables interested users to calculate dose quantities and estimate acute risks for any low Earth orbits (LEO) and beyond LEO missions. Simulation results for dosimeters flown during the Artemis I and International Space Station (ISS) missions with known shielding files and trajectories are reasonably close to their measurements. A set of solar energetic particle forecasting models, University of Malaga Solar particle Event Predictor (UMASEP), are also integrated to provide dose information before or near the onset of solar particle events (SPEs). With archived Geostationary Operational Environmental Satellite (GOES) solar proton data from 1986 to present (real time data updated every 5 minutes), MissionDPT can be used either to analyze the radiation exposure and acute health risks for historical severe SPEs, or to serve as a console tool for flight operational team in contingent scenarios for the upcoming lunar and Mars missions.
