5/16 "Japan evacuates villages outside nuclear zone"--ABC.net.au

Yet another "what do you think" article.
The Japanese government started to evacuate people in areas outside the 30km exclusion zone, after a month of letting people to get ready for evacuation. The area northwest or NPP was high in radiation levels because of wind direction and geography. (Ahem)

Japan evacuates villages outside nuclear zone

www.abc.net.au

Japan began evacuating people from outside the official exclusion zone around the crippled Fukushima nuclear plant after it was revealed fuel rods there probably melted hours after March's devastating earthquake.

Frank Sanns The key here is not meltdown but melted and exposed to air. When the early radiation readings were made they were based on Iodine and Cesium isotopes. The exclusion zone was based on the gamma radiation readings from just those isotopes because they are present in vented gases. Once the core was hot and open to the air, then core material itself was aerosolized and carried by the wind. These materials are typically alpha emitters and are much more dangerous internally than Cesium for example. The selective expansion of the exclusion zone is taking into account the extra dangers of the core isotopes like Plutonium, Americium, Strontium and the like. The evidence has been indisputable in my mind and I have shared that in posts. My only question is why did it take these morons this long to verify what was suspected in March? Were they hiding it or were they hiding from it???

Jill And have been telling and warning people to prepare for, what, a month?

Frank Sanns I do not know the exact areas of evacuation but I would expect them to be where the darkest orange colors are on the map that was posted a few threads back. According to the map, evacuations out to 50 km to the north west of the reactors is possible. There also may be some small isolated areas outside of the elliptical orange area too but nothing close to Tokyo. http://www.facebook.com/l.php?u=http%3A%2F%2Fstatic.ow.ly%2Fphotos%2Foriginal%2FaAT2.png&h=7e91c

I just ran a quick calculation to see what amounts of core materials might be present as a function of distance. Using the 3 km report of neutrons being detected with a conventional instrument and using the inverse square law of fall off (double the distance is one quarter the amount). I came up with a distance of 48 km for the level to be at 1 x 10-9 g/m^2. One nanogram per meter squared with I think would be a reasonable answer. The winds and other factors would weigh in but a 40km to 50km evacuation distance in a particular direction seems reasonable to me.
