经过几十年对低地球轨道的研究，国家航天局和私营企业家正在投资探索太阳系。人类空间探索的主要健康风险是暴露于宇宙射线引起的晚期毒性。在地球上，辐射工作人员受到的照射受到剂量限制的管制，并通过屏蔽和减少照射时间来减轻。对于太空旅行，不同的国际空间机构采用不同的限制，最近如本文所述进行了修改。屏蔽和减少运输时间是目前维持深空飞行任务可接受风险的唯一实际解决方案。
After decades of research on low-Earth orbit, national space agencies and private entrepreneurs are investing in exploration of the Solar system. The main health risk for human space exploration is late toxicity caused by exposure to cosmic rays. On Earth, the exposure of radiation workers is regulated by dose limits and mitigated by shielding and reducing exposure times. For space travel, different international space agencies adopt different limits, recently modified as reviewed in this paper. Shielding and reduced transit time are currently the only practical solutions to maintain acceptable risks in deep space missions.
