The solar particle events of August through December 1989, among the largest ever recorded, are analyzed to assess the potential hazards to humans on interplanetary missions from events of these types. Using the coupled neutron-proton space radiation transport computer code, BRYNTRN, risk estimates for the effects of exposures to the skin, ocular lens, and bone marrow are made for nominal thicknesses of the spacecraft aluminum shielding. Risk assessment in terms of absorbed dose is made for each event. Also presented are estimates of organ absorbed dose and dose equivalent for pairs of events which occurred within 30-day periods, and for the cumulative August through December 1989 period.
对1989年8月至12月期间有记录以来规模最大的太阳粒子事件进行了分析，以评估这类事件对星际任务中的人类可能造成的危害。使用耦合中子 - 质子空间辐射传输计算机代码BRYNTRN，针对航天器铝屏蔽的标称厚度，对皮肤、眼晶状体和骨髓暴露的影响进行了风险估计。对每个事件进行了吸收剂量方面的风险评估。还给出了在30天内发生的成对事件以及1989年8月至12月累计期间的器官吸收剂量和剂量当量估计值。
