Nuclear fission is the process of splitting atoms, releasing heat and radiation. Learn how chain reactions occur and why uranium undergoes spontaneous fission. Discover the impact of fission products and radiation emissions.

Nuclear fission is the process of splitting atoms. • This happens by neutrons hitting atoms and producing fission products which are unstable and so release more neutrons. • A chain reaction can happen if there are lots of atoms close to each other. A neutron is released from one atom and so it hits more atoms which then release more neutrons starting a chain effect. • Nuclear fission happens every day in atoms such as uranium which constantly undergoes spontaneous fission and this is why it emits radiation.
Nuclear Fission • The splitting of an atom releases enormous amounts of heat and gamma radiation. • The neutrons released by the atoms later release beta radiation. • Nuclear fission happens every day in atoms such as uranium which constantly undergoes spontaneous fission and this is why it emits radiation.
