Note: LxC is the likelihood and consequence rating. This risk is mapped to the official (consolidated) HSRB risk "Risk of Adverse Health Outcomes and Performance Decrements resulting from Space Radiation Exposure (Acute, CNS, Degen, Cancer)". The HSRB evaluated the LxC and risk dispositions of this sub-risk for each DRM as part of their review of the consolidated risk.
Risk Statement
Given the known occurrence of solar particle events (SPE) and the inability to predict their occurrence, there is a possibility the crew will suffer from acute radiation sickness (ARS) with the highest likelihood of prodromal symptoms of nausea, vomiting, and fatigue as well as skin damage, and potential hematological/immune changes resulting in LOM if adequate shelter cannot be reached in a timely manner.
