Thank you very much for the question.
Our estimate so far is that direct additional costs to hospitals and clinics are in the order of $1.7 million. Additionally, we have invested in an alternative form of supply, approximately $1.4 million toward the sodium fluoride isotope. The estimate we have is that if things continue under the current regime, and that anticipates that there will not be a reduction in international supply, by the time Chalk River comes back we could well see a quadrupling of those costs.
