Depends on the nuclear reaction - are you referring to neutron induced fission?
Are you talking about the natural radioactivity, maybe you are refering to the 'liquid drop model'.

From memory, a couple of years ago, I think it depends mainly on whether there are an even or odd number of nucleons, the number of nucleons, the shape of the nucleus.

I say number of nucleons because Iron is the most stable, and the high and lower up the atomic number, the more unstable, until Uranium just about holds together.
