I do not think a case can be made for or against nuclear power without a clear understanding of the risks. We are subjected to radiation every day of our lives. I have not seen a clay yet that was not mildly radioactive and radon is detected in many places. The true risk of radiation has not yet been accurately quantified. The problem is that the nuclear industry sets the limits and establishes the safeguards. This is not ideal and does little to inspire confidence. There are studies of radiation from the 2 nuclear weapons exploded over Japan, but there are arguments that they were selective both in choice of subject and interpretation.. Depleted Uranium weapons have been widely used in Iraq and Bosnia. There are studies suggesting an increase in childhood cancers in these area. Others (mainly those that have used them) dispute this. The fog of war, defense secrecy and lack of political will further confuse the true risk.
    All in all trying to quantify risk for nuclear power stations is very difficult because radiation hazard does not appear immediately at low dose levels.Only at high levels of dosage does death occur quickly.
