No, and let me add a point here. We had small 2 Curie sources that were sent thousands of feet downhole, usually offshore. The requirements we had to meet was proof of containment for at least 400 years. With a half-life of 400 years, this means the radioactivity has to be around 200 microcuries before it was considered acceptable for it to leak into the environment...thousands of feet below the surface. There is no way for the danger from that to be anywhere close to background once it got near the surface. Yet, that doesn't matter, rules are rules. No one really complains about that; everyone has accepted ALARA (As Low As Reasonably Achieveable) as one of the requirements. Even if the danger is so low as to be close to unmeasurable, if one can make it lower, one must. My argument is that it is reasonable for the criterion for risk from nuclear power to be the same as risk from anything else.
