+- G4RadioactiveDecayPhysics : assigned the RadioactiveDecay process
+  to G4Triton (which is the only light ion that decays).
+  Note: before, triton did not have beta decay, i.e. it was wrongly
+  treated as stable even when radioactive decay physics was enabled;
+  anti_triton did not, and still does not, have beta decay
+  (because RadioactiveDecay, in its current implementation, does
+  not handle any kind of anti-ions): in practice, this is an acceptable
+  approximation because of its relatively long lifetime and the fact
+  that annihilation and nuclear capture are more likely to happen
+  before decay.
