No. What I was doing was trying to add context.
I put in some things like the sort of levels of uranium that are found in Ontario. Most people have quite a low level of uranium intake because they're drinking town water supplies, which are controlled. People on well water can have huge concentrations of uranium from that water. Normally, you might have, oh, I don't know, but say 5 micrograms per litre, or even less. You can then find wells where there's 800 micrograms per litre. In Bosnia we found some wells that were between 2,000 micrograms and 3,000 micrograms per litre. There's a huge variation in the amount of uranium taken up within the population. Almost everybody in Finland, for instance, drinks water with more uranium in it than the standard set by the World Health Organization. Again, it's a consequence of the local geology and the fact that water contains a lot of natural uranium.
