But, wait a minute! We're still talking about some very small number of cases. Fourteen! 14! Similar studies have found no significant radiation increases near nuclear plants. Could there be another explanation?
"German study finds nuclear energy causes leukemia… or maybe not…" suggests that nuclear plants are in industrial areas, some of which have had severe pollution from other sources, like munition plants. Second, poorer people tend to live near these areas and for a variety of reasons tend to have more health issues, for example, more parents who smoke.
I checked Google for "smoking leukemia" and was given over six million items. Here's one from an "unimpeachable" source - "Kids' Leukemia Risk Tied to Dad's Smoking", Fox News, 2011-12-15 (actually from Reuters). The risk is given as 15 percent higher if the father smokes. The sample size was 400 for children with leukemia and 800 for children without.
I think these cases show that people shouldn't leap to alarmist positions nor should they be quick to dismiss indications of a problem. Unfortunately, our political climate leads to uncritical acceptance of one position or the other.
