New York Times | Japan Checks The Population for Radioactivity
Covering the face and mouth cannot protect against the release of radioactive steam in an effort to cool the nuclear plant core. Detection of higher than normal levels of radioactive elements have been found in 160 individuals with a few showing radiation poisoning.
The government requests the people to remain calm after the announcement of 1000 times normal level detection of radioactive materials.
A meltdown occurs when there is insufficient cooling of the reactor core, and it is the most dangerous kind of a nuclear power accident because of the risk of radiation releases. The radiation levels reported so far by the Japanese authorities are far above normal but still too small to pose a hazard to human health if the exposure continued for a brief period. The fear was that more core damage would bring bigger releases.
List of Radioactive Elements
When a nuclear plant explodes or melts down some radioactive elements released into the atmosphere and water and seeps into ground affecting all life.
