Hybrid Active-Passive Space Radiation Simulation Concept for GSI and the Future FAIR Facility
Space radiation is acknowledged as one of the main health risks for human exploration of the Solar system. Solar particle events (SPE) and the galactic cosmic radiation (GCR) can cause significant
Limitations in predicting the space radiation health risk for exploration astronauts
TLDR
The numerous factors that limit understanding of the risk of space radiation for human crews are highlighted and ways in which these limitations could be addressed for improved understanding and appropriate risk posture regarding future human spaceflight are identified.
MISSION TO MARS: RADIATION SAFETY OR RADIATION DISASTER? SPACE TRANSIT AND MARS RADIATION EXPOSURE RISKS – THE POTENTIAL SHIELDING EFFECT OF AN INTRAVEHICULAR GRAPHENE SPACE SUIT AND A STORM SHELTER DURING SPACE TRAVEL
ABSTRACT Aim The purpose of this research was to employ radiobiological as well as physics principles to investigate materials for an intravehicular spacesuit and a “storm shelter” that might
Limitations in predicting radiation-induced pharmaceutical instability during long-duration spaceflight
TLDR
The risk of space radiation to pharmaceuticals during exploration spaceflight is highlighted, identifying the limitations of current understanding and ways in which these limitations could be addressed through dedicated research efforts aimed toward the rapid development of an effective pharmacy for future spaceflight endeavors.

Shielding and fragmentation studies.
TLDR
To expand the heavy ion database used in the models,Measurement without a target present gives an indication of the level of contamination of the primary beam, which is also important in radiobiology experiments.
Issues in protection from galactic cosmic rays
TLDR
In the absence of an accepted method for estimating astronaut risk, attenuation characteristics are examined using conventional linear energy transfer (LET)-dependent quality factors and a track-structure repair model to fit cell transformation data in the C3H10 T1/2 mouse cell system obtained for various ion beams.
Neoplastic Transformation In Vitro by Mixed Beams of High-Energy Iron Ions and Protons
TLDR
Results indicated an additive interaction under all conditions with no evidence of an adaptive response, with the one possible exception of 10 cGy iron ions followed immediately by 1 Gy protons.
Effect of SPE-like proton or photon radiation on the kinetics of mouse peripheral blood cells and radiation biological effectiveness determinations.
TLDR
The results indicate that the risk estimations for astronauts from exposure of mice to SPE-like proton radiation are comparable to those previously made for doses of standard reference radiations, suggesting that countermeasures should be developed for the decreases in blood cell counts observed following the exposure of mouse toSPE radiation.
Space Radiation: The Number One Risk to Astronaut Health beyond Low Earth Orbit
TLDR
Ground-based research studies employing model organisms seeking to accurately mimic the biological effects of the space radiation environment must concatenate exposures to both proton and heavy ion sources.
