Here is a good news article that discusses radiation levels at the Japanese plant, and how they compare to safe levels.

I suspect that at this stage the power plant operator is trying to maintain safe radiation dosage levels for its employees. But I still wonder if political pressure in Japan will build up to the level where some employees are asked to sacrfice their own safety to solve this reactor problem.

When is a nuclear problem a real "catastrophe", and when is it just a "political and corporate catastrophe"?
