This article argues that Harvard public health studies linking proximity to nuclear power plants with cancer outcomes rely on an ecological methodology that confuses proximity with actual exposure. The authors say the same approach would produce absurd results for unrelated landmarks, suggesting the findings do not establish causation. It also notes that radiation doses for the public near plants are expected to be extremely low or undetectable.
