Reply #18: Could someone explain

[kimsarah]

if there is a sustained nuclear chain reaction that is not temporary _ but rather ongoing, how much worse has it gotten since the accident, how much worse could it get, and what are the worst-case scenario consequences on top of all the contaminated products that have been reported?
How many people are being exposed to high levels, and how much is being dispersed into the atmosphere that could reach other countries like us.
Are West coast residents at risk of high levels, and if so, why isn't the EPA still reporting daily monitoring results?
I realize Tepco has had an interest on minimizing all of this from the onset, but if it is a threat outside Japan, shouldn't our government be more actively involved to get to the truth? We have numerous excellent scientists here -- many of whom are non-government and were drawn upon for their expertise in the days after the accident.
