In Japan, robots are being sent into the stricken nuclear plant. Officials say the first radiation measurements taken inside two reactor buildings show a harsh environment -- but it's not impossible for people to work in.

The radiation should not delay progress toward achieving a cold shutdown of the plant within nine months.
