I really wish they'd stop saying radiation levels 'rising', it's too vague. Cnn is saying the radiation level at the plant is 0.1 to 0.4 sieverts. However, no idea if that's per day or since the blast or what. If it is 0.1 per hour then that would be quite bad. A sievert does not measure the actual quantity of radiation, rather it measures the health effects. So you can have a lot of mildly hazardous radioactivity or just a little gamma radiation to get a particular value. They are saying some nuclear material not in the reactor got caught in the fire. Makes me feel real comfy here in the USA since we store our **** on site (nevada punked out on us).
