Radiation plume could reach Tokyo: U.S. scientists
WASHINGTON | Tue Mar 15, 2011 12:52pm EDT
WASHINGTON (Reuters) - The radiation plume from a nuclear power plant damaged by Japan's devastating earthquake and subsequent tsunami could reach Tokyo, a U.S. scientists' organization said on Tuesday.
The Union of Concerned Scientists also said a "jerry-rigged" cooling system at the Japanese plant would be hard to maintain if all workers there were evacuated.
Nuclear power and safety experts at the group said they were "very concerned" that ongoing activities at the plant would become more challenging for on-site workers. A larger radiation plume could travel hundreds of miles (km), the scientists said in a telephone briefing.
A crack in the containment vessel could allow radiation to exit the reactor in case of a core meltdown, the scientists said. They said the Japanese government should extend the evacuation zone around the troubled Fukushima Daiichi power station.
Japan faced a potential catastrophe on Tuesday after a stricken nuclear power plant exploded and sent low levels of radiation floating toward Tokyo, prompting some people to flee the capital and others to stock up on essential supplies.

About 150 residents near the Fukushima Daiichi site have been checked for radiation and 23 have been decontaminated. Japanese authorities have distributed potassium iodide tablets to evacuation center (see this?page?for more information on potassium iodide). If taken within several hours of ingesting radioactive iodine, potassium iodide can protect the thyroid gland.
Pour l'Autorité de surêté nucléaire, l'accident japonais est de niveau 6 sur 7, sur l'échelle internationale des événements nucléaires. Pour l'AIEA, il para;t "très improbable" que la crise actuelle dégénère en une situation comparable à celle de l'accident de Tchernobyl.
