| Abstract: | In connection with projects on a manned base on the Moon, the assessment of radiation risk to staff of the base owing to galactic (GCR) and solar (SEP) cosmic radiation becomes very relevant. The paper describes the methodology for assessing the radiation environment on the lunar surface and in the depths of lunar soil taking into account the primary and secondary radiation caused by protons and nuclei of GCR and SEP. Calculated fluencies of particles are used to estimate the average annual absorbed and equivalent local doses in tissue. Contribution to the dose of secondary neutrons at depths of lunar soil exceeds the contribution of protons. Contribution to the dose of secondary particles generated by GCR nuclei should be taken into account. |
