Using the coupled neutron-proton space radiation transport computer code (BRYNTRN), estimates of human exposure in interplanetary space, behind various thicknesses of aluminum shielding, are made for the large solar proton events of August 1972 and October 1989. A comparison of risk assessment in terms of total absorbed dose for each event is made for the skin, ocular lens, and bone marrow. Overall, the doses associated with the August 1972 event were higher than those with the October 1989 event and appear to be more limiting when compared with current guidelines for dose limits for missions in low Earth orbit and more hazardous with regard to potential acute effects on these organs. Both events could be life-threatening if adequate shielding is not provided.
利用耦合中子-质子空间辐射传输计算机代码（BRYNTRN），针对1972年8月和1989年10月的大型太阳质子事件，对不同厚度铝屏蔽层后的行星际空间中人体暴露情况进行了估算。针对每个事件，对皮肤、晶状体和骨髓的总吸收剂量风险评估进行了比较。总体而言，1972年8月事件相关的剂量高于1989年10月事件，与当前低地球轨道任务剂量限制指南相比，似乎更具限制性，且对这些器官的潜在急性影响更具危险性。如果没有提供足够的屏蔽，这两个事件都可能危及生命。
