 It showed us a couple of things, it showed us that this is a problem that we have not really seen very clearly, but it's a problem that's going to be with us for a while. It's a global problem, which is you have over 450 nuclear plants that in existence functioning today around the world, many of them very aging, many of them with standards of management and protection and emergency preparation, much inferior to what the Japanese have. You have another 60 being constructed today. So what we saw in Japan was the future in a way. It was a warning that look, even in a place that is as well prepared as Japan, you have this sequence of events happens, it exposes your population and you realize that preparedness was not adequate. The scientific standards are not adequate about what do you know about exposure to radiation and what do you tell the population.
