Nuclear fission fragments<\/strong> are the fragments left after a nucleus fissions<\/a>. The average of the fragment mass is about 118, but very few fragments near that average are found. It is much more probable to break up into unequal fragments, and the most probable fragment masses are around mass 95 (Krypton) and 137 (Barium). Most of these fission fragments are highly unstable<\/strong> (radioactive) and undergo further radioactive decays<\/a> to stabilize themselves<\/a>.<\/p>\n
