| 摘要: |
| 月球表面没有磁场的保护，粒子辐射是人类在月球活动的重要风险要素。概述了月球的辐射环境以及辐射来源，并介绍了月球探测的现状，特别提及了近年来几个较为典型的月球辐射探测实例及其探测结果；介绍了我国“嫦娥4号”上搭载的月表中子与辐射剂量探测仪（Lunar Lander Neutron&Dosimetry，LND）的科学目标及其技术指标。LND的科学目标主要包括：载人登月辐射剂量的测量、月球南极艾特肯盆地水含量的测量、艾特肯盆地FeO含量的测量，以及为日球层科学的研究提供依据。 |

| Abstract: |
| 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. |
