a: neutron ~
b: a bullet
What:
"Every once in a while, decaying uranium nucleus gives off a neutron. This extra neutron is like a bullet. If it strikes another uranium nucleus, it can split the nucleus in half. Splitting the heavy uranium nucleus is called nuclear fission. When nuclear fission takes place, an enormous amount of heat is released, along with lots of radioactivity."
