Ever since the Fukushima nuclear crisis, there has been widespread speculation about it's global impact. A team of Stanford researchers have figured that out, and thankfully, the answer to that is reassuring.
Using 3D global atmospheric models developed over the last 20 years, Stanford researchers predicted that the likely transport of radioactive material around the globe and how it would affect the health of the population and estimated that we could expect to see 130 deaths as a result of the incident and 180 extra cancer cases over a longer time period.
The figures include Japan. The final predictions are very broad because the resulting radionuclide concentrations are low in most places, making the number extremely small. No reason to go ape shit crazy and panic. [Stanford]
