Importance of Radiation Exposure as a Risk to Astronaut Health

Now let’s turn to nutritional countermeasures against radiation-enhanced cancer. As noted earlier, risks posed to personnel in space by naturally occurring radiations are among the most serious limitations to human space missions, with the primary risk from radiation exposure being later cancer development. Radiation-enhanced cancer has a priority #1 on the Bioastronautics Roadmap. Of all the cancer risks likely to be enhanced by radiation, colon cancer is among the leading concerns. It is the second leading cause of cancer deaths in the United States today and strikes men and women more or less equally.
