When you look at a risk and a hazard, you need to look at the probability of the event happening and then the consequence of the exposure.
The probability of something going wrong once the boilers are loaded and transported down to Sarnia is very low. When was the last time a boat sank? When was the last time a boat of this sort had an accident? There isn't any history of that.
Then on the consequences, what would happen if it if did sink, and how quickly could they get the boilers back out? What is the thought on damage? For all these things, if you've read the CNSC proposal, some of this has been dealt with. The risk of exposure is very low, and the consequence is also very low.
To me, this is not a huge human health risk. If you consider the risk due to a motor vehicle accident or to the results of smoking and so on, those increase the risks to humans far more. Even on the amount of radiation, the amount of radiation that is shipped every day to hospitals doing cancer therapy is orders of magnitude higher than this, and it is shipped without anybody's knowledge.
