Scientists from the NASA Center in Houston offered a way to predict the degree of probable damage to the health of astronauts from cosmic radiation. This is reported by Izvestia.
Nasa Johnson Space Center specialists proposed a way to determine the individual radio sensitivity of the crew members of cosmic missions through the impact on the blood samples of gamma rays. The method was developed on the basis of data 38 of astronauts aged from 37 to 57 years who flew to the International Space Station (ISS) from 2001 to 2013.
Researchers compared the effect rendered to the blood of the cosmonauts impact of gamma rays in laboratory conditions, with the action of cosmic radiation on the ISS, which could be identified by samples taken after the flight is completed.
Depending on the number of damaged by chromosomes after irradiation in the laboratory for each astronaut, experts built a computational model at which its individual radio sensitivity could be determined. Comparison of the calculated indicators with real, which were obtained after the return of astronauts to the Earth, confirmed the high accuracy of the developed model.
