The Space Radiation Analysis Group (SRAG), located at the Johnson Space Center, is a part of NASA responsible for ensuring astronaut radiation exposure remains within safety limits. SRAG provides radiological support during missions, pre-flight exposure projections, and evaluates radiological safety related to equipment on spacecraft. They utilize comprehensive modeling capabilities and radiation instruments to characterize the radiation environment and minimize risks to humans in space, adhering to the ALARA principle (As Low As Reasonably Achievable).
