Yes, but they also consume them. The uranium fuel used has a halflife measured in billions of years, the materials they produce have halflives measured in only hundreds or thousands of years. So in the long term balance of things they consume radioactive substances faster than they produce them.
So far there are no known reasons to use radioactive substances in wind turbines.
