I ran example Hadr06 with attached macro : thermal neutron on a block of Co59, with and without radioactive decay registered (see PhysicsList.cc).
As you can see, without radioactive decay, only neutron capture happens. With radioactive decay, one can see the decay Co60 --> Ni60
Of course, this case test only neutronHP. You can re do the exercise with different, simple situations involving cascade packages.
