Space Radiation and Cancer Risk in Astronauts: Models, Evidence, Uncertainties, and Emerging Imaging Perspectives [PDF]

Tomography
Cancer risk estimation remains one of the main unresolved challenges in human spaceflight beyond low Earth orbit, where astronauts are exposed to galactic cosmic rays, solar particle events, and high-linear energy transfer (high-LET) secondary radiation.

Enhancing Astronaut Resilience: The Role of Elevated ROS in Adapting to Space Radiation [PDF]

Journal of Biomedical Physics and Engineering
The microgravity environment and high radiation levels in space lead to a significant increase in Reactive Oxygen Species (ROS) production compared to Earth, which can have detrimental effects on astronaut health over time.

Rare diseases and space health: optimizing synergies from scientific questions to care

npj Microgravity, 2022
Knowledge transfer among research disciplines can lead to substantial research progress. At first glance, astronaut health and rare diseases may be seen as having little common ground for such an exchange. However, deleterious health conditions linked to

Radiation Risks in a Mission to Mars for a Solar Particle Event Similar to the AD 993/4 Event

Aerospace, 2021
Within the past decade, evidence of excess atmospheric 14C production in tree rings, coupled with an increase in annually resolved measurements of 10Be in Arctic and Antarctic ice cores, have indicated that an extremely large solar particle event (SPE ...
