Norwegian Institute For Air Research: Radiation Fallout For April 22-25.
Check the NILU’s latest forecasts: see their list http://transport.nilu.no/sitemap –> scroll down to products, pick the folder Fukushima: http://transport.nilu.no/products/fukushima and then you can choose for which radioactive gas/particle to view the forecasts (Xenon-133, Cesium-137 or Iodine-131) in the box with the blue buttons. Meanwhile, the Fukushima Dai-ichi plant continues to spew its menace:
For the airborne radioactive fallout / cloud: It looks like far-northern California’s coast will get another, albeit relatively small, “whiff” after this weekend, concentrated around the Humboldt/Mendocino coast. Nothing like we’ve seen in the last few weeks, but in spots it’s still 3 Bq/m^2 (3 becquerel per square meter). 10,000 square meters is a square kilometer, which is about 0.39 square mile.
I just checked if the US EPA had done something about the USA’s almost surreal pathetic radiation monitoring network… (Belgium and Holland combined have more than double the monitoring stations than all of North America combined. Just saying…) Nope:
FAIL. Or to make it more visually obvious… In Japan huge differences in fallout have even been observed within 1 square kilometer (see here for an example). So, just for fun: if fallout were to settle on US soils distributed as shown below, the EPA RadNet wouldn’t even notice a thing! I colored areas within about 50+ miles from an EPA monitor in green; made up dangerously high values for the rest (yellow, red, magenta), just to show how inadequate this “network” is:
