In doing our analysis for the bill, in setting the limit we undertook a study, a kind of risk assessment in terms of what kinds of incidents, what kinds of risk scenarios we should be considering. In effect, when we looked at a worst-case scenario, a worst-case design-basis incident at a facility, in those situations we found that in fact the radionuclides were maintained within the facility, and they were vented in a controlled manner. So it would be unlikely that you would have a situation where you would be contaminating a large water body.
