Discovery Of Neptunium-239 (Decays Into Plutonium-239) In Iitate-Mura Finally Published In Scientific Paper (Nearly 1 Year After Discovery)


Media Concealed Leaked TEPCO Report: 120 Billion Becquerels of Plutonium, 7.6 Trillion Becquerels of Neptunium (Decays Into Plutonium) Released In First 100 Hours

Huge Amounts Of Neptunium 239 Detected 60 Km From Fukushima!!!

Discovery of Neptunium-239 in Iitate-mura Finally Published by a Peer-Review Magazine (Nearly One Year after the Discovery) (EX-SKF, Mar 4, 2012):

A paper by a researcher at Tokyo University about discovery of neptunium-239 and other short-lived nuclides in Iitate-mura seems to have finally been accepted and published by Environmental Pollution, a peer-reviewed scientific magazine. It was made available online on January 20, 2012, and is published in the April 2012 issue of the magazine.

It took nearly 1 year for off-line readers to know about the discovery. The researcher took the samples of soil, plants and water in early April last year.

In August last year there was an article of neptunium-239 having been discovered in Iitate-mura, 35 kilometers from Fukushima I Nuclear Power Plant, by a researcher at Tokyo University. The article was written by a husband and wife comedian couple. (For more, see my post on August 15, 2011.) They were criticized for not revealing the source (name of this researcher) or the details. Their response was that the researcher was submitting the paper to a peer-reviewed magazine.

Well here it is, published by a peer-reviewed magazine nearly one year after the accident, and now utterly irrelevant except for some academic curiosity. The information, as it sat in limbo of peer-reviewing process, was not used to educate, warn people in Fukushima, particularly in Iitate-mura, so that they could decide what to do. If they had known their soil and vegetation were extremely contaminated with short-lived radionuclides with strong radioactivity, they might have done things differently.

I hope the researcher at least warned the villagers privately.

ALERT! – Saint Louis, MO: Radioactive Rain At 2.76 mR/Hr, 270 Times Over Background Radiation, Highest Reading So Far (Oct. 17, 2011)

YouTube Added: 23.10.2011

The Day THYROID CANCER Was Thrust Upon Saint Louis, North America: Monday 17th of October 2011

The POTRBLOG team has been able to identify a 19.25 hour half life and a follow on 4.8 day half life component in the radioactive fallout which rained down on Saint Louis, Missouri on Monday 17th of October 2011. The half lives and decay chain indicate the presence of radioactive Iodine 133 and its daughter product Xenon 133.

As evidenced by alternating Saint Louis, Mo fallout detections of Neptunium 239 and currently of Iodine 133 + Xenon 133, Fukushima is cycling between a free flowing neutron rich criticality creating Neptunium-239 — Plutonium 239 and a neutron “poisoned” criticality where Iodine-133 — Xenon 133 is both the neutron poison and primary fallout product.

Media Concealed Leaked TEPCO Report: 120 Billion Becquerels of Plutonium, 7.6 Trillion Becquerels of Neptunium (Decays Into Plutonium) Released In First 100 Hours

News: Media knew 1.2×10^12 Bq of plutonium was released to the air in the first 100 hours (Fukushima Diary, Oct. 14, 2011):


The Report which Tepco made for press conference on 6/6/2011 was leaked on the internet.

According to the report, Tepco already announced that Plutonium 238, 239, 240, 241 was released to the air in the first 100 hours after the earthquake.

It reads the amount is 120 BILLION Becquerels.

When it comes to Np-239, it is 7,600 BILLION Becquerels.

It is possible to assume a certain amount of them have flown to around Tokyo.

Knowing the fact, Media kept concealing the risk for 7 months and kept people exposed.

MAXIMUM ALERT: Persistent Long Half Life Radioactive Fallout Detected In Saint Louis (Video)

YouTube Added: 10.10.2011

Twenty Six days after the initial radioactive rainfall on 9/14/11, the radioactive sample swipe taken from our truck still shows radioactivity at approximately 6 counts per minute above background levels. Based on the decay data, the POTRBLOG team strongly suspects that a primary component of this persistent long half life fallout is the Neptunium 239 , Plutonium 239 series; and, that it is highly prudent to take risk mitigation actions.

Japan: New Government Maps Show Wide Dispersion of Plutonium and Strontium

Ministry of Education Maps of Plutonium and Strontium Show Wide Dispersion of Supposedly Heavy Nuclides (EX-SKF, Sep. 30, 2011):

On September 30 the Ministry of Education and Science posted the blurry maps plotting the locations where plutonium and strontium have been detected.

(On the same day, September 30, the national government abolished the evacuation-ready zone between the 20 and 30 kilometer radius from the plant, “allowing” the residents to return.)

Japan Admits Plutonium 35 Km From Fukushima Plant

Ministry of Education Admits to Plutonium in Iitate-mura in Fukushima (EX-SKF, Sep. 30, 2011):

35 kilometers northwest of Fukushima I Nuclear Power Plant.

Jiji Tsushin (5:42PM JST 9/30/2011):


Ministry of Education and Science disclosed on September 30 that plutonium has been detected from the soil in Futaba-machi, Namie-machi and Iitate-mura in Fukushima Prefecture, which derived from the Fukushima I Nuclear Power Plant accident. According to the Ministry, it is the first detection of plutonium outside the plant.

Readers of this blog have been alerted to the existence of neptunium-239 (which decays into plutonium-239) in the soil of Iitate-mura, so it should be no surprise. It is no surprise at all either that it has taken more than 6 months for the Ministry of (Re-)Education to admit.

Neptunium-239 has reportedly been detected in Date City also. That’s even further away from the plant (60 kilometers).

Neptunium-239 (Decays Into Plutonium-239) Potentially Detected In Saint Louis Radioactive Rainfall (09/14/2011)

For your information…

[MAXIMUM ALERT] Neptunium 239 Potentially Detected In Saint Louis 9/14/11 Radioactive Rainfall (Sep. 16, 2011):


The source has a calculated average 2.4 day half life. The half life matches Neptunium 239. Np239 decays into Plutonium 239.

IF WE ARE LUCKY, the source will not be Americium 243 but rather Uranium 239 (in Fukushima); given the 2.4 day half life of Np 239, it is possible that source came directly across the jet-stream as Np-239. The result would be higher levels of Np-239 and Plutonium 239 the further west one went from Saint Louis.

Otherwise, the source would probably be Americium 243 created in the MOX fuel reactor at Fukushima Unit 3.

UPDATE 9/17/11:

The video below records raw data being taken from the 1.33 mR/hr radioactive rainfall which fell in Saint Louis, Mo on 9/14/11. This data was taken after shorter half life contamination had mostly burned off.

The data shown is from one hour total count readings taken of the radioactive source, and local background. The raw data from the later part of the video has yet to be fully analyzed.




Fukushima Released 76 TRILLION Bequerels Of Plutonium 239

NISA Mentions “Neptunium-239” in August 29 Press Conference (Ex-SKF, August 28, 2011):

Now this is very curious.

The Nuclear and Industrial Safety Agency (NISA)’s daily press conference is ongoing (August 29). The NISA spokesman Moriyama mentions neptunium-239’s conversion ratio to plutonium-239 as 1 to 1.

According to the June 6 estimate by the NISA:

Plutonium-239: 3.2×10^9

Neptunium-239: 7.6×10^13

So, now it is:

Plutonium-239: 7.6 x 10^13, or 76,000,000,000,000 or 76 terabecquerels

The amount of plutonium-239 has increased 23,000-fold.

Neptunium 239 Detected In Soil 38 Km From Fukushima Nuclear Plant

Breaking News: Whistle-blower of neptunium239 was purged (Fukushima Diary, August 16th, 2011):

A couple of days ago, the report that they detected thousands Bq of neptunium239 in Iidate mura shocked the whole world.

However, the people who blogged about the report were purged.

They are comedy duo called “Oshidori mako/ken”.

The comedy duo had one of their TV programs cancelled by the TV sponsor.

They told the duo,”TV show is a product to sell,so we can’t be against our sponsor.It’s taboo to talk about Tepco and Genpatsu at variety program.”

The duo was imposed silence on which TV channel and what TV show it is,but they say it is the major one.

Here we can learn two things from this.

1) Detection of neptunium239 was crucially important.They needed to conceal the fact to keep the nuc power going on.

2) They purge.!/makomelo/status/103063395267391488!/makomelo/status/103067446667259904!/makomelo/status/103121130763714560!/makomelo/status/103122327901974528

Neptunium 239 Detected In Soil 38 Km From Fukushima Nuclear Plant

Neptunium-239 Detected from Soil in Iitate-mura in Fukushima??? (EX-SKF, August 15, 2011):

(Correction: my initial post said “several thousand becquerels per kilogram”, but on checking the original Japanese post there is no mention of “per kilogram” or per any other unit.)

The information comes from a strange source – the husband and wife comedian couple cum independent journalists attending and reporting on TEPCO and the government press conferences when they are not on stage.

In their blogpost on August 11 (in Japanese), they relate their talk with a researcher at the University of Tokyo who has submitted a scientific paper to a foreign academic society. This researcher, whom they say they cannot name because the paper is being reviewed right now, went to Fukushima and collected soil samples, rice hay samples, and water samples. He even went to the front of Fukushima I Nuclear Power Plant and collected samples there.

He also went to Iitate-mura. And he tells the couple that he found neptunium-239 in Iitate-mura, about 38 kilometers from the plant, in approximately the same amount as he found at the front gate of Fukushima I Nuclear Power Plant. That is the topic of his paper.
