雷电产生也产生X射线和伽马辐射,只是持续了很短的时间,大约是十万分之一秒。 然而,一项新的研究显示,雷电的电离辐射似乎比推定的要长得多。 产生伽马辐射余辉,持续时间长达10 000倍

Simulations by CWI researchers showed an afterglow of gamma radiation after lightning, which lasted up to up to 10,000 times longer than previously assumed. The image shows the altitude and time of the radiation. The color (red to yellow) indicates the radiation strength. A terrestrial gamma flash that starts at an altitude of 8 kilometers, creates a cloud of neutrons (blue) at an altitude of 3 kilometers. This cloud, in turn, creates the afterglow. Credit: CWI
