Someone was looking for a house in Port Hope and didn't want it to be near any undiscovered nuclear fuel dump so they bought and old, old house. Turns out it had been owned by a scientist at the nuclear facility and the present day testing equipment showed him coming in the door from work everyday and heading to the bathroom for a shower. They didn't have the same understanding of the dangers of nuclear material back then. This is a story I clearly remember some man telling my family when I was a teen young adult but I can't remember who. It may have been at the time of my brother's graduation from private school there.

Kind of like Hanford in Washington State. I was curious about cancer rates in the Port Hope area and found this abstract from a 2013 study that seems to indicate no increase in cancer rates in that region compared to Ontario as a whole.

the scientist was coming home from the nuclear lab in the 1930s. I wonder what the cancer rate was for that generation of lab workers.
