I think everyone knows that there are large ethical issues on conducting studies specifically on children, but there were studies done. When the safety code was developed, there were not live children but models of children's brains and of the size of children to look at the effects of radiation exposure on tissue that would be like children's. Let me just say that.
Second, the Interphone study, which came out in the spring of this year, recommended long-term studies on children. It was a multinational study that looked at cellphone exposure. One of their recommendations, which Health Canada thoroughly supports, is having longer-term studies on exposure, particularly with children. We're very supportive of that. We would welcome long-term studies, just as all the other studies are very welcome. As I said, we review them on an ongoing basis.
