Governments Underreported Severity of Fukushima
As I’ve noted for
6 months, the Japanese and U.S. governments have continually under-reported the severity of the nuclear crisis at Fukushima.
The Wall Street Journal
points out:
The Japanese government initially underestimated
radiation releases from the Fukushima Daiichi nuclear plant, in part
because of untimely rain, and so exposed people unnecessarily, a report
released this week by a government research institute says.
PhysOrg
writes:
The amount of radiation released during the Fukushima
nuclear disaster was so great that the level of atmospheric radioactive
aerosols in Washington state was 10,000 to 100,000 times greater than
normal levels in the week following the March 11 earthquake and tsunami
that triggered the disaster.

[A] study [by University of Texas engineering professor Steven
Biegalski and researchers at the Pacific Northwest National Laboratory]
reports that more radioxenon was released from the Fukushima facilities
than in the 1979 meltdown at the Three Mile Island Nuclear Generating
Station in Pennsylvania and in the 1986 Chernobyl nuclear disaster in
the Ukraine.
Biegalski said the reason for the large release in Fukushima, when
compared to the others, is that there were three nuclear reactors at the
Japan facilities rather than just one.
Nuclear expert Arnie Gundersen
notes:
New TEPCO data measured on August 19 & 20 shows
severe damage to the spent fuel in Fukushima Daiichi Units 1, 2, and
3…. This TEPCO data clearly contradicts and refutes the July assertion
by the NRC the Fukushima Daiichi spent fuel pools were not damaged in
this tragic accident.
There are also several
unconfirmed reports that the Japanese government is trying to keep people from buying geiger counters to measure radiation.
New, Large Radiation Releases Are Possible
Mainichi Dailly News
notes:
As a radiation meteorology and nuclear safety expert at Kyoto University’s Research Reactor Institute, Hiroaki Koide [says]:
The nuclear disaster is ongoing.
***
At present, I believe that there is a possibility that massive
amounts of radioactive materials will be released into the environment
again.
At the No. 1 reactor, there’s a chance that melted fuel has burned
through the bottom of the pressure vessel, the containment vessel and
the floor of the reactor building, and has sunk into the ground. From
there, radioactive materials may be seeping into the ocean and groundwater.
***
The government and plant operator TEPCO are trumpeting the operation
of the circulation cooling system, as if it marks a successful
resolution to the disaster. However, radiation continues to leak from
the reactors. The longer the circulation cooling system keeps running,
the more radioactive waste it will accumulate. It isn’t really leading
us in the direction we need to go.
It’s doubtful that there’s even a need to keep pouring water into the
No.1 reactor, where nuclear fuel is suspected to have burned through
the pressure vessel. Meanwhile, it is necessary to keep cooling the No. 2
and 3 reactors, which are believed to still contain some fuel, but the
cooling system itself is unstable. If
the fuel were to become overheated again and melt, coming into contact
with water and trigger a steam explosion, more radioactive materials
will be released.

We are now head to head with a situation that mankind has never faced before.
Mainichi also
reports:
The Ground Self-Defense Force (GSDF) and residents of the
zone between 20 and 30 kilometers from the stricken Fukushima No. 1
nuclear plant held an emergency evacuation drill on Sept. 12 … in preparation for any further large-scale emission of radioactive materials from the plant.
***
The scenario for the drill presupposed further meltdown of the
Fukushima plant’s No. 3 reactor core, and a local accumulation of
radioactive materials emitting 20 millisieverts of radiation within the
next four days. …
And nuclear
expert
Paul Gunter says that we face a “China Syndrome”, where the fuel from
the reactor cores at Fukushima have melted through the container
vessels, into the ground, and are hitting groundwater and creating
highly-radioactive steam:
