A two-month stint on the moon could expose astronauts to about the same amount of radiation since they’d get living on the International Space Station for five weeks, based on new dimensions in the lunar surface.
An astronaut will be subjected to a typical daily dose of 1,369 microsieverts of radiation, researchers report online September 25 at Science Advances.
That is about 2.6 times as large as the typical daily radiation exposure of 523 microsieverts recorded within the ISS, the scientists state. Being around the moon” for 2 weeks could be OK. That’s about precisely the identical amount of radiation astronauts get in the ISS [more than five weeks ] and would not be incredibly harmful,” says co-author Robert Wimmer-Schweingruber, a physicist in Christian Albrechts University at Kiel, Germany.
“That is [a] pretty cool piece of information.” He warns that radiation levels across different areas of the space station might be greater, hence the writers may have over projected the vulnerability difference between the moon’s surface along with the ISS.
Galactic cosmic rays, high energy charged particles that zip through distance, come from beyond the solar system. Earth’s magnetic field shields people from such beams, but in distance, it is a completely different story.
Thus far, it is unclear exactly what effect such vulnerability may have on human health. The impacts of spending a massive quantity of time in distance may reveal many years after a person was exposed, states Marjan Boerma, a radiation biologist at the University of Arkansas for Medical Sciences at Little Rock.
The findings come at a time when the United States and other countries are making programs to land people on the moon for the first time in years (SN: 12/16/19). NASA has declared its plans to property the initial U.S. girl and a guy on the moon’s surface by 2024.
