Contaminated seawater spreads north

Highly radioactive iodine seeping from Japan’s damaged nuclear complex may be making its way into seawater further north of the plant than previously thought, officials said today, adding to radiation concerns as the crisis stretches into a third week.

Mounting problems, including badly miscalculated radiation figures and no place to store dangerously contaminated water, have stymied emergency workers struggling to cool down the overheating plant and avert a disaster with global implications.
