Current Status of Radiation Environment Detection on the Lunar Surface

There is no magnetic protection on the lunar surface,so particle radiation is an important risk factor for human activities on the Moon. In this paper,the radiation environment and radiation sources of the Moon are summarized,and the current situation of lunar exploration is also introduced,particularly several typical lunar radiation detector. Then, the science objectives of Lunar Lander Neutron & Dosimetry (LND) Experiment on Chang'E-4 are explained, including dosimetry for human exploration of the Moon, contributions to heliospheric science, determination of the subsurface water content in the south-pole Aitken basin and the FeO content in the south-pole Aitken basin.
