The new measurements show that the level of radiation on the moon is two to three times higher than the International Space Station.
The measurements were taken by an instrument on China’s Chang-4 lunar lander. The spacecraft came down from the far side of the moon in January 2019.
German and Chinese scientists involved in the experiment say Chinese landers provided the first “active” measurement of radiation levels on the lunar surface. These findings were reported in a recent publication study Science progress.
The study was carried out as plans to send astronauts to explore the moon developed in the United States and many other countries. The American space agency NASA aims to land the first woman and the next man on the moon by 2024 as part of its Artemis program. It aims to establish a long-term base on the moon by 2028.
But space radiation presents major health hazards for future astronauts. Cancer is a major health concern, but radiation Get in touch Other diseases can also result.
NASA has already warned that if astronauts spend longer in places like the Moon or Mars, they will face higher levels of harmful radiation.
Earth’s atmosphere and magnetic .ال Protect human beings from the extreme radiation in the universe. But astronauts aboard the International Space Station receive more than 10 times the amount of radiation we receive on Earth.
A new study suggests that radiation exposure to the moon will be 2.6 times greater than that of the International Space Station. Researchers say astronauts on the moon will receive 200 times more radiation than we experience on Earth.
Robert Weimer-Schweingruber is an astrophysicist at Kill University in Germany. He helped lead the research. He told the French press agency, AFP, that his team from the discovery had predicted that astronauts would only be able to stay on the moon for about two months under current conditions.
Humans are not really made for this radiation level and should protect themselves while on the moon, said Wimber-Swingruber.
He added that the radiation levels should be the same in all areas of the moon, except for rad walls Pit. “Basically, the less you see the sky the better.”
The researchers suggested that astronauts could build shelters made of lunar dirt for protection over a period of more than a few days. They said the walls of the shelters should be about 80 centimeters thick. Thicker than that wall, they said, dirt could block off its own secondary radiation. Such radiation is then produced Cosmic rays Interaction Moon with clay.
NASA has said it will contain radiation Detectors And a safe haven flying over the moon on all its crew spacecraft.
Thomas Burger is a physicist at the German Space Agency’s Institute of Medicine. He also participated in the study. He called the results of the experiment “ImmeasurableThe method ultimately provides scientists with a “data set” that can be used to effectively measure radiation and study its effects on humans, Berge said.
The radiation levels described in the study are similar to the levels predicted by the models. Carrie Lee is a space radiation specialist at NASA’s Johnson Space Center in Houston. Lee said the measurements made by the detector on NASA’s orbiter “almost agree” that it has been orbiting the moon for more than 10 years.
“It’s nice to see confirmation of what we’re thinking, and how radiation interacts with the moon is in line with our expectations,” Lee said.
