- One study showed that for a recent period of 11 years, there was a strong correlation (or association) between the numbers of people who drowned in swimming pool and the amounts of power generated by nuclear power plants (based on data from the Centers for Disease Control and Prevention and the Department of Energy). Does this imply that increasing power from nuclear power plants is the cause of more deaths in swimming pools?
