Comments about a “dust-sized particle” (left at

I beg to differ (with Dr.Keiraleyn). Or perhaps not, but probably. Can she specify the exact size she assumed for the “dust-sized particle of Plutonium” referred to by qrrrrr? If a millionth of a gram of plutonium in your lung is likely to be a lethal dose, or at least the LD/50, and a dust particle is a millionth of a gram or larger, then qrrrrr is correct. If a dust particle is a millionth of a millionth of a gram, then what Dr. Keiraleyn writes would probably apply. But Dr. Keiraleyn never specified the exact size of HER dust particle, and apparently assumed a very minuscule size for qrrrrr’s. Also, she completely denigrates the latent cancer deaths as being something that “only” occurs following a “lag period of years to decades” as if that’s much of a hoped-for future for today’s infants. Sure, google pu health effects. And also please visit my book (a free download about nuclear poisons, at ), and Beyond Nuclear, and NIRS, and so on. These sites might not come up as often as the well-funded nuclear industry sites, but have lots of good information nonetheless!

If you breathe in or swallow a dust-sized particle of Plutonium, you are dead. It’s one of the most toxic substances on Earth.

I beg to differ. If you swallow a particle of plutonium, it will most likely be excreted in feces, as it is not well absorbed through the digestive tract. If you inhale plutonium particle(s), the health effects will be different depending on the size of the particle and whether it migrates out of the lungs into other areas of the body, such as the bone marrow. Research in animals also clearly shows a dose-response relationship on health — that is, if one inhales LOTS of plutonium particles, as might occur if one were present in an accident at a nuclear power plant or nuclear weapons facility — the health effects will be vastly more serious than if one inhales lesser doses, or a single “dust-sized particle of Plutonium” as you describe. The health effects of this low level of exposure you mention are difficult to study because it is virtually impossible to determine whether one has in fact inhaled such a particle. However, equating this level of exposure with “you are dead” is both completely unsupported by any epidemiological research with people who HAVE been exposed to particulate plutonium (such as workers at nuclear weapons manufacturing plants) and it is irresponsible fear-mongering, as well. There are substances far more toxic than plutonium, including naturally occurring isotopes of radium. In any case, even if inhaling a single “dust-sized particle” of plutonium resulted in death, it would likely only be following a lag period of years to decades, because plutonium in such minuscule doses can only kill by causing cancer by irradiating body tissue that it is lodged immediately adjacent to over long periods of time. For readers who would like to obtain further detailed information concerning health hazards of plutonium, just Google “Plutonium Health Effects” and you will find a great deal of information available from a wide variety of sources. — Susan Keiraleyn, Ph.D.
The lunatics running the assylum? No, just greedy simplistic “we have the answers to your problems” big business as usual, but it’s blowing up in their faces as it is becoming more apparent as time moves on. (Science saves,?? responsible technology??) No. Just a brief grief in the history of time. PS Why not read what it says at Revelation 11v18 about those who are ruining the earth ? Is that the ultimate answer for all of our woes? In reply to some of the critics spouting their ignorance and lack of understanding recently on natural news,– computers are handy– but running about in cars ————— UNSUSTAINABLE !!!!!!!!!!!!!! TRY WALKING. (ditch the plane Mike -no more embarassing searches) Ask a genius how it’s done. You need time to do it PPS I reckon that to be a genius the first 1500 years would possibly the hardest.

MOX plutonium fuel used in Fukushima’s Unit 3 reactor two million times more deadly than enriched uranium

Thursday, March 17, 2011 by: Ethan A. Huff, staff writer

(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 (…).

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. You can read the entire MOX report for yourself here:…
