Kjarnaeinkjarófsgeislun
Kjarnaeinkjarófsgeislun translates to "nuclear fission fragment decay" in English. This process refers to the radioactive decay of the unstable fragments produced during nuclear fission. When a heavy atomic nucleus, such as uranium or plutonium, undergoes fission, it splits into two or more lighter nuclei. These resulting nuclei, known as fission fragments, are often highly unstable and possess an excess of neutrons.
To achieve stability, these fission fragments undergo a series of radioactive decays, typically beta decay and
The decay of these fission fragments is a significant source of delayed neutrons and heat in nuclear
