Well, I suppose, radioactive decay is of negative use in chemistry and engineering.
One interesting counterexample to this is deuterium and water made from it. It is 11% denser than normal water, ice made from it sinks in normal water, it has a higher heat capacity, is more viscous and has a higher boiling point. It's also completely stable!
