Thank you for the question.
Chalk River, as you noted, has been on site for a wealth of years now—from the very beginning in terms of the Cold War and working through different research. The low-level radioactive waste currently being overseen at Chalk River—we have site inspectors doing regular walkabouts to ensure radioactive waste management and monitoring programs are adhered to—is in things like overalls, cleaning supplies and mopheads. Those make up the bulk of the low-level radioactive waste found at Chalk River. Again, why are they there? When you work with radioactive material, you need to clean things up, so other things get contaminated.
We have a classification system we've identified in our regulatory documents to better understand the difference between low-level, intermediate-level and high-level waste and tailings, because we have uranium mines here in Canada as well.
I hope that answers your question.
I don't know if Ms. Fabian Mendoza has anything further to add on the low-level waste inventory at Chalk River.
