Summary
Detailed male and female anatomical models aid space radiation analysis by estimating astronaut organ doses and cancer risks from space radiation environments.
Area of Science:
- Space science
- Radiation biology
- Medical physics
Background:
- Computerized anatomical male (CAM) and female (CAF) models are crucial for space radiation analysis.
- Current model detail may be insufficient for some radiological applications.
Purpose of the Study:
- To review existing CAM and CAF models for space radiation analyses.
- To solicit user requirements for improving these anatomical models.
- To demonstrate the utility of these models for astronaut radiation exposure estimation.
Main Methods:
- Extrapolation of dosimetry measurements (skin doses) to astronaut body organ doses using Space Shuttle program methods.
- Utilizing trapped Van Allen belt and galactic cosmic radiation environment models.
- Incorporating data from historical solar particle events.
Main Results:
- Demonstrated the application of CAM and CAF models in estimating astronaut organ doses.
- Provided mission scenarios showcasing model utility for exposure assessment.
- Established a basis for cancer morbidity and mortality risk assessments.
Conclusions:
- CAM and CAF models are valuable tools for space radiation dosimetry.
- Further model refinement is needed based on scientific user feedback.
- These models are essential for astronaut radiation safety and risk assessment.
