Enable the probe that I sent China To the moon in 2019 from clarifying an issue that was not resolved by the American Apollo missions related to the exact level of radiation on the moon, which is one of the basic data, at a time when the US space agency, NASA, is preparing to send astronauts this year to the moon for long periods.
On Friday, a team of Chinese and German researchers published in the journal “Science Advances” the results of the test conducted by the “Chang E-3” probe, which recorded daily radiation exposure to the surface of the moon, and it was found that the degree of these radiations is 2.6 times greater than that of members. The International Space Station crew.
One of the study’s authors, astrophysicist Robert Wimmer Schweingruber of the University of Kiel, said that the degree of radiation on the moon “is between 2 and 3 times stronger than on the International Space Station.”
He believed that this “shortens the period of stay on the moon to about two months,” explaining that this takes into account the week it takes for the journey from Earth to the moon and the return trip.
And radiation, whether cosmic or solar, at certain levels can lead to long-term damage that ranges from cancer and cataracts, through to neurological diseases.
The unit sievert measures the radiation absorbed by human tissue.
The radiation on the moon is 1,369 Sv per day, which is 2.6 times more than the daily dose on board the International Space Station, in which the crews generally stay for six months, noting that some of them stayed a year or more.
The radiation is less intense inside the station because it is partially protected from cosmic rays by the Earth’s magnetosphere. As for the Earth, it is more protected by the atmosphere, but this protection is lessened with altitude.
Intends to ”NASA“Returning to the moon in 2024 for the first time since 1972 and establishing an infrastructure to send astronauts periodically to serve as an exercise in sending the first human to Mars.
Professor Wimer Schweingerberger proposed building radiation-shielded housing in the event of a stay for more than two months on the moon, by covering it with a layer of lunar soil with a thickness of 80 cm.
