Astronaut exposure to galactic cosmic rays (GCR) and solar particle events (SPEs), presents a critical challenge for long duration space exploration missions. Experimental studies have shown that HZE nuclei found in the GCR produce both qualitative and quantitative differences in biological effects compared to terrestrial radiation, leading to large uncertainties in predicting exposure...

The Badhwar-O'Neill (BON) Galactic Cosmic Ray (GCR) flux model has been used by NASA to certify microelectronic systems and in the analysis of radiation health risks for human space flight missions. Of special interest to NASA is the kinetic energy region below 4.0 GeV/n due to the fact that exposure from GCR behind shielding (e.g., inside a space vehicle) is heavily influenced by the GCR...

There are large uncertainties connected to the biological response for exposure to galactic cosmic rays (GCR) on long duration deep space missions. In order to reduce the uncertainties and gain understanding about the basic mechanisms through which space radiation initiates cancer and other endpoints, radiobiology experiments are performed with mono-energetic ions beams. Some of the...

For vehicle design, shield optimization, mission planning, and astronaut risk assessment, the exposure from galactic cosmic rays (GCR) poses a significant and complex problem both in low Earth orbit and in deep space. To address this problem, various computational tools have been developed to quantify the exposure and risk in a wide range of scenarios. Generally, the tool used to describe the...

42. Validation of NASA Space Radiation Analysis Tools with ISS Radiation Environment Monitor (REM) Data

A variety of computational tools and models are used by NASA to evaluate astronaut radiation exposure in support of vehicle design and mission planning efforts. These space radiation analysis tools include radiation environment models, transport codes, and vehicle shielding models. Measurements made with the Radiation Environment Monitor (REM) units currently onboard the International Space...
