In the current legislation, the limit is 10 years for a bodily injury. We recognize, because of the scientific evidence, that certain cancers are only experienced or are latent until some 20 to 23 years after radiation exposure. That is why we have moved, similar to the international conventions, to the 30-year limit. The problem with extending it even further is that it becomes very difficult to prove causation at much longer periods, and you'll find that the insurers certainly don't insure beyond the 10 years because of the problems of proving causation.
