He even includes the dose you get from yourself (potassium-40), flying in a plane, the famous "chest xray" often used for comparison. You can compare doses by comparing areas, very clever. Every time I post something from XKCD, someone complains about me "pimping my blog", so to be proactive, this is not a blog, it is not MY blog, I get nothing from this. XKCD has built an interesting table...

The radiation level of 1,000 MilliSieverts (MSV) at the power plant in Fukushima, Japan is hundred Rem. A person in America gets a year 620 Rem of radiation. The only diff is, that 1,000 MSV (100 Rem) per hour at Fukushima, is way higher than 620 Rem spread through the 8,760 hours a year. of course, if a person reads that the radiation level at the plant is 400 MSV per hour (instead of 1000 MSV P/H that it once reached), the person indeed knows that it is a high level. However, with the above information at hand, one understands...
