Plutonium Tales


Fukushima plutonium levels said no threat March 9 2012

[excerpted] TOKYO, March 9 (UPI) -- "Plutonium levels at Japan's Fukushima nuclear power plant aren't much higher than what is in the environment from Cold War-era nuclear tests, researchers say...

Researchers examining the area within a roughly 20-mile radius of the damaged plant found levels of radioactive plutonium were about double those from residual fallout from U.S. and former Soviet Union above-ground nuclear tests at the dawn of the Cold War, levels still well below representing any threat to humans, the Los Angeles Times reported..."

Majia here: Can this be true when the NRC transcripts essentially confirm that unit 3, which used MOX fuel, was utterly destroyed (both the reactor pressure vessel and the spent fuel pool)?

[excerpted] March 21: A Second Massive Release of Radiation
 
On the morning of March 21 the wind was blowing from the north. In areas downwind from the Fukushima Daiichi Nuclear Plant (including the Fukushima Daini Nuclear Plant and the cities of Kita Ibaraki, Takahagi and Mito), levels of airborne radiation suddenly spiked. What caused this abnormal jump? 

According to Tanabe Fumiya, an expert in nuclear power, at this same time the air pressure inside the pressure container of the No. 3 reactor, the one that used MOX (a mixed oxide fuel containing both plutonium and uranium), suddenly soared to 110 times the normal level. Because of this extremely high pressure, it was no longer possible to add cooling water from outside; as a result, the damaged fuel rods in the reactor once again went into meltdown, and the resulting build up of steam led to an explosion. 

The molten remnants of the fuel rods then breached the pressure container and leaked to the floor of the containment vessel. Tanabe concludes that the blast caused some of the radiation to escape the reactor, leading to contamination of the downwind region, an area extending from the interior of Fukushima prefecture to Kita Ibaraki.7.

On March 23, a new plume formed, moving southwest from the coastal areas of Ibaraki through Chiba prefecture. During this period, most of the Kantō region saw several days of rain, resulting in accumulations of radioactive materials on the ground across the region.8 ...

MAJIA HERE: Propaganda works because people fail to analyze data carefully. Usually propaganda can be revealed by conflicting data and analyses.

I conclude that there exists a propagandistic media campaign to persuade the public that the plutonium from Fukushima is not a threat, despite the destruction and essential vaporization of unit 3's reactor and spent fuel pool (the reactor with MOX fuel, which is plutonium enriched).
