How bad are atomic bombs for you? asks Instapundit, before linking to a story about a chap who is still going strong after surviving the bombings of both Hiroshima and Nagasaki.
This is actually an important question, as no humans have been exposed to as much radiation as the survivors of these bombings.
Turns out, if you are lucky enough not to be vapourised in the first instance, humans are extremely resilient.
This study (okay, I'm sorry about the journal it comes from) has followed 120,000 atomic bomb survivors who received high doses of radiation - and found their life expectancy has been shortened, on average, by four months.
