月球和火星任务的辐射分析

Radiation Analysis for Moon and Mars Missions

Andreas Märki

摘要:

本文概述了载人航天飞行到月球和火星的辐射方面。在阿波罗11号飞往月球的飞行路线上,对宇航员的预期电离辐射剂量进行了评估。利用这两个剂量值,估算了预期总剂量和实测总剂量、辐射屏蔽和太阳活动。为了判断风险或安全裕度,辐射对人体的影响是反对的。太阳辐射必须在计算机模型中设置为零,以达到阿波罗11号飞行的辐射剂量值。银河系和宇宙粒子也没有被建模。阿波罗11号的宇航员一定是幸运的,在他们的飞行中,太阳在1969年的太阳极大年完全安静-以及他们随后的阿波罗飞行的同事,即直到1972年,公布的剂量值仍然需要一个安静的太阳。这里建立的数学模型允许通过仅改变飞行持续时间来评估火星之旅的总剂量。即使在此期间提出更厚和/或主动辐射屏蔽,载人航天飞行到月球和火星的辐射风险仍然巨大。

英文摘要:

This paper provides an overview of the radiation aspects of manned space flight to Moon and Mars. The expected ionizing radiation dose for an astronaut is assessed along the Apollo 11 flight path to the Moon. With the two dose values, the expected and the measured total dose, the radiation shielding and the activity of the Sun are estimated. To judge the risk or safety margin the radiation effects on humans are opposed. The radiation from the Sun has to be set to zero in the computer model to achieve the published radiation dose value of the Apollo 11 flight. Galactic and cosmic particles have not been modelled either. The Apollo 11 astronauts must have been lucky that during their flight the Sun was totally quiet in the solar maximum year 1969 - and also their colleagues of the subsequent Apollo flights, i.e. until 1972, where the published dose values still require a quiet Sun. The here built mathematical model allows assessing the total dose of a journey to Mars by only changing the flight duration. Even if in the meantime much thicker and/or active radiation shielding is proposed the radiation risk of manned space flight to Moon and Mars remains still huge.
