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 that crew is exposed to radiation from the space environment, there is the possibility that they will develop cardiovascular disease, including cerebrovascular, microvascular, and other degenerative tissue effects such as diseases associated with accelerated aging.
