... This is not the only possible reaction: a variety of daughter isotopes are produced (As, Br, Sr, Zn, and Zr), some of which are stable, but most of which are radioactive themselves (e.g. as -, + or emitters). These reaction can release 1, 2 or 3 neutrons, and on average 235U fission releases 2 n ...
