“#New measurements show moon has hazardous radiation levels<\/strong>”

\n CAPE CANAVERAL, Fla. \u2014 Future moon explorers will be bombarded with two to three times more radiation than astronauts aboard the International Space Station, a health hazard that will require thick-walled shelters for protection, scientists reported Friday.<\/p>\n

China\u2019s lander on the far side of the moon is providing the first full measurements of radiation exposure from the lunar surface, vital information for NASA and others aiming to send astronauts to the moon, the study noted.<\/p>\n

A Chinese-German team reported on the radiation data collected by the lander \u2014 named Chang\u2019e 4 for the Chinese moon goddess \u2014 in the US journal Science<\/a> Advances.<\/p>\n

\u201cThis is an immense achievement in the sense that now we have a data set which we can use to benchmark our radiation\u201d and better understand the potential risk to people on the moon, said Thomas Berger, a physicist with the German Space Agency\u2019s medicine institute.<\/p>\n

Astronauts would get 200 to 1,000 times more radiation on the moon than what we experience on Earth \u2014 or five to 10 times more than passengers on a trans-Atlantic airline flight, noted Robert Wimmer-Schweingruber of Christian-Albrechts University in Kiel, Germany.<\/p>\n

\u201cThe difference is, however, that we\u2019re not on such a flight for as long as astronauts would be when they\u2019re exploring the moon,\u201d Wimmer-Schweingruber said in an email.<\/p>\n

Cancer is the primary risk.<\/p>\n

\u201cHumans are not really made for these radiation levels and should protect themselves when on the moon,\u201d he added.<\/p>\n

Radiation levels should be pretty much the same all over the moon, except for near the walls of deep craters, Wimmer-Schweingruber said.<\/p>\n

\u201cBasically, the less you see of the sky, the better. That\u2019s the primary source of the radiation,\u201d he said.<\/p>\n

Wimmer-Schweingruber said the radiation levels are close to what models had predicted. The levels measured by Chang\u2019e 4, in fact, \u201cagree nearly exactly\u201d with measurements by a detector on a NASA orbiter that has been circling the moon for more than a decade, said Kerry Lee, a space radiation expert at Johnson Space Center in Houston.<\/p>\n

\u201cIt is nice to see confirmation of what we think and our understanding of how radiation interacts with the moon is as expected,\u201d said Lee, who was not involved in the Chinese-led study.<\/p>\n

In a detailed outline released this week, NASA said the first pair of astronauts to land on the moon under the new Artemis program would spend about a week on the lunar surface, more than twice as long as the Apollo crews did a half-century ago. Expeditions would last one to two months once a base camp is established.<\/p>\n

NASA is looking to put astronauts on the moon by the end of 2024, an accelerated pace ordered by the White House and on Mars sometime in the 2030s.<\/p>\n

The space agency said it will have radiation detectors and a safe shelter aboard all Orion crew capsules flying to the moon. As for the actual landers, three separate corporate teams are developing their own craft with NASA oversight. For the first Artemis moon landing, at least, the astronauts will live in the ascent portion of their lander.<\/p>\n

The German researchers suggest shelters built of moon dirt \u2014 readily available material \u2014 for stays of more than a few days. The walls should be 80 centimeters (about 2 1\/2 feet) thick, they said. Any thicker and the dirt will emit its own secondary radiation, created when galactic cosmic rays interact with the lunar soil.<\/p>\n

\u201cSo in this sense \u2014 I think the walls of European Castles would be too thick!\u201d Berger wrote in an email.\n <\/p><\/div>\n
