Innovators at NASA's Johnson Space Center have developed modeling software that estimates the effect of radiation exposure on a human. The software provides estimates of whole body effective dose, organ doses, and acute radiation sickness symptoms for astronauts should they be exposed to solar particle events during space exploration missions. The Acute Radiation Risk and BRYNTRN Organ Dose (ARRBOD) projection graphical user interface (GUI) provides seamless integration of input and output manipulations for the operation of the BRYNTRN, SUMDOSE, and acute radiation risk (ARR) projection modules. Through the assessment of gender-specific organ dose assessments, mission planners and radiation shield designers can use the ARRBOD GUI to develop optimal shielding solutions that will help astronauts avoid ARR symptoms and stay within current NASA short-term dose limits. This software may be released for U.S. Government purposes only.


  • Integrated: Provides a user-friendly interface for complex models, enabling accurate analysis of radiation dose and acute risks in a timely manner
  • Straightforward: Assists mission planners without the need for extensive data preparations and manipulations
  • Flexible: Offers easy-to-use desktop tool for general biophysics applications
  • Accurate: Identifies proper shielding solutions (and offers alternatives) for attaining determined objectives


  • Mission planning
  • Spacecraft shield design
  • Biophysics aerospace research
