LengyelSubject: International Space Station Program/Radiation Exposure/Research in Health Physics Description of Driving Event: Adequate Resources for th
2、e Study of Radiation ExposureLesson(s) Learned: By virtue of the several ongoing programs for the human exploration of space, NASA is pioneering the study of radiation exposure in space and its effects on the human body. Research that could develop and expand credible knowledge in this field of unkn
3、owns is not keeping pace with operational progress.Recommendation(s): Provide the resources to support more completely research in radiation health physics.Evidence of Recurrence Control Effectiveness: NASA concurs with the recommendation. The funding for radiation research has been augmented over t
4、he past couple of years. Expanding support for radiation health physics research will benefit the mitigation of effects of space radiation and the accurate determination of organ doses. NASAs Space Radiation Health Program supports basic research in radiobiology and biological countermeasures. The R
5、adiation Health Program has initiated efforts to provide reference dosimetry capabilities for flight dosimetry at Loma Linda University and Brookhaven National Laboratory. A phantom torso is being used to assess organ doses on Shuttle and ISS. JSC has initiated efforts to improve measurements of the
6、 neutron contribution to doses in LEO. These efforts include increasing opportunities to use neutron detector systems and the development of a high-energy neutron detector by the National Space Biomedical Research Institute (NSBRI).
