| Abstract: | In connection with projects of manned bases on the Moon it becomes topical to estimate radiation danger for their inhabitants.
In this paper we describe a method of evaluation of the radiation environment on the lunar surface produced by galactic and
solar cosmic rays. The roles of both primary and secondary radiations generated in the depth of the lunar soil under the action
of high-energy protons and nuclei are taken into account. Calculated fluxes of particles are used in order to estimate annual
averaged absorbed and equivalent local dose rates in tissues. It is established that in the lunar rock the contribution of
secondary neutrons to the dose rate exceeds that of protons. The contribution of the secondary particles generated by nuclei
of galactic cosmic rays to the dose rate is estimated. |
