Note: LxC is the likelihood and consequence rating. The information above was last approved by the Human System Risk Board (HSRB) on 2/18/2020 under the previous 3x4 LxC matrix. The HSRB has now migrated to a new 5x5 LxC matrix as defined in the new Risk Management Plan (approved 10/01/2020) which may change the risk rating once brought forward for approval.
Risk Statement
LxC is the likelihood and consequence rating. The information above was last approved by the Human System Risk Board (HSRB) on 2/18/2020 under the previous 3x4 LxC matrix. The HSRB has now migrated to a new 5x5 LxC matrix as defined in the new Risk Management Plan (approved 10/01/2020) which may change the risk rating once brought forward for approval. This risk is scheduled to be updated at the HSRB within the next 6 months.

Given crew is exposed to radiation from the space environment, there is the possibility for increased cancer morbidity or mortality.
