Contamination | Two Fukushima workers were hospitalized Thursday 24th May for high-level radiation and injuries to their legs.
Contamination | Japanese parents told not to let infants drink tap water. Radioactive iodine levels are above legal limit for babies.
Reactors | All Fukushima reactors now connected to power. Electricity has not been reestablished in crucial systems, however.

Reactors | Fukushima emergency workers have been evacuated temporarily, as smoke rises from reactors 2 and 3.
Death toll | Japanese police has reported 21,911 dead or missing as of noon, March 21. 350,000 people are living in refugee camps.
Economy | World Bank estimates rebuilding cost could be as high as 4% of Japan's GDP, as much as $230 billion, but impact will be "short-lived."
