The findings come from the German Aerospace Center, which reports that without adequate protection, the human body cannot cope with this surface radiation for any long time. According to the measurement results, the cosmic radiation on the surface of the moon is about 200 times greater than that on the ground. < p > < p > the chang’e-4 probe arrived on the surface of the moon in January 2019, carrying the surface neutron and radiation dose detector (LND) from Germany. In the months after its arrival, LND measured the space radiation found on the moon’s surface, providing unprecedented data that will be crucial for future lunar missions, especially those requiring long stays on celestial bodies. < / P > < p > of course, space radiation is a significant risk to the human body, as the human body is not able to handle exposure to this level of radiation. This is a big problem for space agencies and private companies planning to send astronauts to the moon for long-term exploration missions, which may expose them to a greater risk of cancer and other radiation related diseases. In order to provide a reference frame for the measurement results, Dr. Thomas Berger of the Medical Research Institute of the German Aerospace Center said: < / P > < p > the radiation exposure we measured is a good measurement of radiation in space suits. The measured equivalent dose rate – the bioweighted radiation dose per unit time – is about 60 microsevers per hour. For comparison: the long-distance flight from Frankfurt to New York has a dose rate of about 1 / 5 to 1 / 10 and 1 / 200 on the ground. Therefore, staying on the moon for a long time is a heavy burden on human body. < / P > < p > the key to future lunar missions is that the moon has no atmosphere and magnetic field, which means that the moon will be subject to a lot of space radiation. With this data, space agencies will be able to use computer models to determine the radiation exposure to any particular mission concept and help experts develop appropriate protective equipment to protect the health of astronauts.
