Yes.
We do two things. We do cobalt-60 and we do medical isotopes. NRU was the primary supplier of our medical isotope molybdenum-99, and that has stopped. That had a gigantic impact on our business. NRU also continues to be a cobalt-60 supplier for that specialized segment of cobalt-60 for cancer treatment today. But you're correct that the majority of our industrial cobalt comes from power reactors.
