3号機はプルサーマルを開始していました。つまり炉の中の燃料集合体

(燃料棒の束)にウランとプルトニウムを混ぜた“mox”燃料の棒を混ぜて

ありました。

 下記記事によるとプルトニウムの毒性はウランの200万倍です。

 そしてその半減期は2万4千年。

 下記記事は大手マスコミがこのことに触れていないとあきれている

ようです。名前からして大手商業新聞ではないのでしょう。

 記者は例の3号機の爆発のときにプルトニウムが空気中に出な

(NaturalNews) Largely absent from most mainstream media reports on the Fukushima Daiichi nuclear disaster is the fact that a highly-dangerous
"mixed-oxide" (MOX) fuel in present in six percent of the fuel rods at
the plant's Unit 3 reactor. Why is MOX a big deal? According to the
Nuclear Information Resource Center (NIRS), this plutonium-uranium
fuel mixture is far more dangerous than typical enriched uranium --
a single milligram (mg) of MOX is as deadly as 2,000,000 mg of normal
enriched uranium.

On March 14, Unit 3 of the Fukushima reactor exploded, sending a
huge smoke plume into the air. This particular reactor, of course,
contains the rods fueled with MOX. You can watch a clip of that
explosion here:

If even a couple milligrams of MOX were released during this explosion
-- or if other explosions at the plant inflict any damage on the MOX-
filled rods -- then the consequences could be exponentially more
devastating than the mere leakage of enriched uranium. And since
nobody knows for sure exactly which rods have been damaged, and
whether or not the situation can actually be contained, it is only a matter
of time before the world finds out for sure.

An exact quote from the report reads:

"In the event of such accidents (involving the accidental release of
MOX), if the ICRP (International Commission on Radiological Protection) recommendations for general public exposure were adhered to, only about
one mg of plutonium may be released from a MOX facility to the
environment. As a comparison, in [sic] uranium fabrication facility,
2kg (2,000,000 mg) of uranium could be released in the same radiation
exposure."

A simple calculation reveals that one mg of MOX is basically two million
times more powerful than one mg of uranium. This is clearly not a good
thing when the plutonium-containing fuel rods in Fukushima may be
damaged from the recent explosions and leaking into the environment.

A recent National Public Radio (NPR) piece explains that the half-life
of plutonium-239, a component of MOX, is an astounding 24,000 years.
The same piece explains that if even a small amount of this potent
substance escapes from the plant in a smoke plume, the particles will
travel with the wind and contaminate soil for tens of thousands of years (http://www.npr.org/2011/03/16/13460... ).

Amazingly, most mainstream reports that mention MOX discount it as a non-threat. But the truth of the matter is that the threat posed by MOX is very serious. The NIRS report explains that inhalation of MOX radioactive material is significantly more dangerous than inhalation of normal uranium radioactive particles.
