To discussed the main research progress of cosmic radiation injury assessment for astronauts at present, to look forward to the future research direction, and to provide ideas for further research of cosmic radiation injury assessment.

Domestic and international papers and monographs in this field.

Fifty two published research papers and reviews were cited.

With the rapid development of the space industry, the assessment of astronaut's cosmic radiation injury has become the high light of aerospace medical research. At present, there are new attempts and explorations in radiation dosimeter, radiation pre-estimation and biological dose assessment. The above three types of radiation detection and evaluation technologies have their own advantages and characteristics. Comprehensive application of radiation assessment technology can meet the needs of short distance and short-time manned space flight missions. However, each technology has its limitations, such as poor anti-interference ability, unstable detection performance, and inability to quickly and accurately complete the detection of large quantities of specimens.

The application of current radiation dosimeter, radiation preestimation calculation technology and radiation biological effect assessment technology can roughly meet the requirements of radiation dose estimation. The existing radiation assessment technology reserves are far from meeting the needs of the follow up development of manned spaceflight for medium and long term, as well as broad space missions. Therefore, rapid, stable, accurate and high flux radiation dose assessment methods still need further exploration.
