Thank you for the question. It's quite apropos.
The quantities of uranium used to produce isotopes are quite small. We're talking about very small quantities. The natural uranium can be sourced from anywhere around the world; I pointed to Saskatchewan as one of Canada's repositories. The technology we're describing actually produces the same types of isotopes that are currently produced from isotope production reactors, so it's the same distribution of isotopes.
As to whether these isotopes in demand by the clinical and medical community save more lives than are risked in the mining of uranium, I confess I'm not an expert on weighing those costs and benefits. However, I can point to the continued basis for the demand for molybdenum-99 and its derivative, technetium. We've heard experts say that's very important to the clinicians, so those doctors are making those calculated judgments.
