太阳活动与先天畸形之间的联系:电离辐射足以解释它吗?

A link between solar events and congenital malformations: Is ionizing radiation enough to explain it?

摘要:

已知宇宙射线直接或通过其次级辐射产生的电离辐射造成生物效应。这些影响已在航空公司机组人员和人口成员暴露于高于平均水平的二次通量的其他特定情况下被检测到。最近的研究发现了太阳粒子事件和先天畸形之间的相关性。在这项工作中,我们使用的计算模拟的结果,以近似的电离辐射从这样的事件,以及在宇宙射线通量的长期增加。我们发现,这些事件产生的电离辐射量不足以产生先天性畸形,根据目前的范式关于μ子电离辐射。我们认为,需要进一步的工作,以确定正确的电离辐射贡献的宇宙成因μ子。我们认为,更广泛的测量μ子辐射效应可能会显示出更大的贡献电离辐射剂量比目前假设的。

英文摘要:

Cosmic rays are known to cause biological effects directly and through ionizing radiation produced by their secondaries. These effects have been detected in airline crews and other specific cases where members of the population are exposed to above average secondary fluxes. Recent work has found a correlation between solar particle events and congenital malformations. In this work we use the results of computational simulations to approximate the ionizing radiation from such events as well as longer term increases in cosmic ray flux. We find that the amounts of ionizing radiation produced by these events are insufficient to produce congenital malformations under the current paradigm regarding muon ionizing radiation. We believe that further work is needed to determine the correct ionizing radiation contribution of cosmogenic muons. We suggest that more extensive measurements of muon radiation effects may show a larger contribution to ionizing radiation dose than currently assumed.
