When they stepped out of the car the last time, the radiation was about 45 times the amount that sets off the "Jesus Christ get out of there" alarm.

also: poor dogs =(

There's this: http://cl.ly/2V3c33023U0Y1e0s2X0T

Unfortunately the citation for that is "some dude on reddit" but you can find plenty of debate and other sources in the comments here:

xkcd posted what appears to be an excellent chart explaining radiation doses: http://xkcd.com/radiation/

A radiologist friend of mine confirms that 5+ Sv is generally considered a fatal dose (assuming you trust her) Her guess is that whatever source said that 1,000 Sv results in radiation sickness probably meant 1,000 mSv, which = 1 Sv.

oh ok, that makes sense seeing that they were reading levels of +/- 92 mSv/h.

oops, no I'm wrong 92uSv/h

According to my calculations, it would take ~ 3 weeks of living in the final place where they got out, 1.5km from the plant, to be at a statistically significant higher risk for cancer.

It would take almost 8 months of living at that close proximity to suffer from mild radiation sickness (headache, increased risk of infection).

A few more months, and you will begin to die. Nausea, and fatigue are more symptoms. Even if you the leave zone, there's still a 10% chance that you'll drop dead within a month.

If you're made of steel, and you're somehow still alive after two and a half years, you will be hairless and permanently sterile.

My calculations don't indicate at which point you turn into a ghoul.

ここから出て行け, スタルカ！

Sadly, you're right.
