To repeat something of what I said earlier, I was assured a very short time ago—last week, I think—that there would be no shortage of I-131. In the last two days, I've been hearing that there is a shortage this week, and you've been hearing that this is true. I have had a number of e-mails from patients who are concerned and want to know the situation. It appears from what Dr. McEwan has said that this is a hiccup in the system that will iron itself out, and that we'll be okay overall in terms of iodine.
The advantage of iodine over technetium is that it has a longer half-life. You can stockpile it in a small way, and you can ship it longer distances with less loss. So we should be okay, I think.
