欧洲现在根据一项新立法对飞机上接收的剂量进行监测。法国操作系统 SIEVERT 是为了计算银河宇宙射线和太阳粒子的剂量而开发的。然而，在太阳粒子事件期间进行的飞行测量非常少，并且对太阳宇宙射线效应的全面计算也很少。半经验模型 SiGLE 基于过去对 GLE 的观察而使用，以提供飞机上可能接收的剂量的连贯图。在三个不同幅度的典型 GLE 期间计算大量路线的潜在暴露。它针对自 1942 年以来观察到的过去 GLE 期间的两条路线给出。SiGLE 模型的结果与一些 GLE 可用的其他剂量率估计值进行了比较，显示出合理的一致性。还使用 SiGLE 模型研究了严重的地磁风暴对太阳耀斑期间接收的剂量率的影响。
Doses received on board airplane are now monitored in Europe in application of a new legislation. The French operational system, SIEVERT, has been developed to calculate doses due to galactic cosmic rays and to solar particles. Nevertheless, very few in-flight measurements have been performed during solar particle events and full calculations of solar cosmic ray effects are also rare. The semi-empirical model, SiGLE, is used on the basis of past observations of GLEs to provide a coherent picture of doses potentially received on board airplane. Potential exposure is calculated for a large number of routes during three typical GLEs of different amplitudes. It is given for two routes during the past GLEs observed since 1942. Results of SiGLE model are compared to other dose rate estimates available for a few GLEs, showing a reasonable agreement. The effect of severe geomagnetic storms on dose rate received during solar flares is also studied using SiGLE model.
