The Chernobyl deniers use far too simple a measure of radiation risk | Comment is free, the Guardian

Just read this. My immediate thought is that surely an average dose is the right way to go when we’re talking about risks to civilians who get an average rather than swallowing alpha emitters? But then this is probably wrong because there are alpha emitters in the air from disaster zones flowing into them?

What this shows is that this debate is ridiculously difficult to have (and also that I can’t remember any of my A-level Physics).
