The impact of radiation release
("Risk to Environmental Health"), triggered by earthquake and tsunami ("Disaster Trigger Event"), caused the release of the radiation ("Man-Made Hazard"), which was precipitated by site blackout and subsequent loss of cooling system capacity ("Vulnerability Factors").
Its radiation release
was less significant than that of Chernobyl but the impact is still under study.
An investigation of a radiation release

This quantity is comparable to the radiation release
from about 500 atomic bombs of the type dispatched onto Hiroshima in 1945.
Our own plants, we hope, are less immediately vulnerable, but unforeseen combinations of natural disasters, human incompetence, and even terrorist attacks make radiation release
all too real a possibility on our own soil.
The severity of the Fukushima accident has been compared to the devastating 1986 Chernoby1 meltedown(the world's worst nuclear accident) in which thousands suffered from the radiation release
When you add the radiation release
from the damaged nuclear reactors, this sequence surely must fall into the low-probability, unthinkable category .
MOX, made from plutonium that is capable of being used in nuclear weapons, is harder to control during reactor operation and results in a more serious radiation release
in the event of an accident.
Summary: Japan admits that burying a crippled nuclear plant in sand and concrete may be the only way to prevent a catastrophic radiation release
There are dangers for radiation release
that could affect the immediate vicinity of nuclear plants and potentially could drift over other parts of Japan, he said.
Scientists say these kinds of anomalies simply aren't explained by official radiation release
Ukraine has previously said it had already registered 4,400 deaths related to the accident, and early speculation following the radiation release
predicted tens of thousands would die.
