Yesterday the Minister of Health talked about alternatives, including saying provincial governments and so forth were developing other measures to minimize impact, including alternate isotopes such as thallium. But as I understand it from talking to some of the doctors, the thallium technology, which is 20 years old, is not nearly as useful or as good for most procedures. The benefit of nuclear medicine is it allows the doctors to see how the organs are functioning. With thallium they can get a little bit of an idea but not nearly as good as with normal nuclear isotopes. Is that right?
