Before I pass it on to Mr. Jammal, there are two quantities, if you like. That's why I think people are misunderstanding the comparison. There is the weight and there's the activity. The weight of the total radioactivity material inside a steam generator is about four grams, and it's diffused right through the whole piping. The activity in there is a different kind of thing, and when you use a Geiger counter outside the shell you measure it at one metre, because it's the standard of measurement of safety. So at one metre away from the steam generator, it's less than one metre away from a radioisotope box that does medical isotopes. Basically, that's really the comparison we're trying to make here. In terms of safety--and that's our number one concern--this is safer than some of those boxes that have been shipped all around.
