Black Stuff Mystery Gets Stranger, Is Magnetic, We Look Into What It Is

The ongoing mystery of the black stuff gets another twist. Someone in Minamisoma took a sample and separated it with a sieve.
The larger pieces had about 50 uSv while the fine matter had 100 uSv. The fine matter is also slightly magnetic. This raised the
obvious question of what could it be to be radioactive and magnetic. This is the detector used in the video. The video here.

We looked at a number of possible substances. Some are paramagnetic. This type can be influenced by heavy magnets under certain
conditions but probably not the manner seen in the video. A household magnet generally can’t attract a paramagnetic substance.

Our team has been researching the past 2 days trying to determine potential sources for the substance and have run through a long list of possibilities.
We also tried to sort these based on substance properties to come up with a list of potential sources.
Some guesses we had on possible substances:
Lava rock/sand or tuff = paramagnetic, radioactive somewhat due to uranium content
Iron/steel = magnetic, iron or steel isn’t normally radioactive and attracts more rapidly to a magnet than the video substance.
Uranium = paramagnetic, alpha radiation emitter
Plutonium = paramagnetic,  alpha radiation emitter
Thorite/thorium/monazite = magnetic property, non magnetic unless a magnetic source is part of the total composition, alpha radiation emitter
Zirconium = diamagnetic, the zirconium metal as used in metals manufacturing is not on it’s own radioactive.
Zircalloy = could be slightly magnetic if part of the alloy is a magnetic metal such as steel, not radioactive as a produced metal.

This other video of black stuff found at another location in Minamisoma was tested for alpha radiation. It was found to have:
Without Paper: 22.53 microSv/h of combined alpha, beta, and gamma radiation
With Paper: 9.008 microSv/h of beta and gamma radiation (alpha blocked by paper)
The remaining 13.522 microSv/h is the alpha radiation
A considerable portion is alpha so we looked at possible alpha emitters. The video of the magnetic stuff in the lab did
not test for alpha vs. gamma ratio but both samples were found in the same town.

americium-241  – paramagnetic
plutonium-236 –   paramagnetic
uranium-238  – paramagnetic
thorium-232  – ?
radium-226  – nonmagnetic
radon-222 86 – nonmagnetic (gas)
polonium-210 84 – nonmagnetic

Radium, radon and polonium can be ruled out by lack of magnetic property. The possibility of some naturally occuring radium or polonium can be ruled out.
Pure forms of thorium can be ruled out as they are not magnetic. Thorium such as monazite sands could be a possibility if the mix had something magnetic in it.
Monazite sands are not common in Japan. Japan does have a few black sand beaches but they are not monazite sands from what we were able to determine.
Simple soil and road runoff could contain fallout but wouldn’t be magnetic.

Thorite varieties found in Japan are not black in color and do not appear to be magnetic. So thorite is likely not the substance. So thorium containing substances such as thorite or monazite are unlikely as far as being originated from Japan.

Lava rock and volcanic tuff can have uranium in it and give off some radioactivity. It is not magnetic so likely not the substance in the first video.

We certainly do not have a definitive answer what this substance is, but many naturally occurring possibilities can be ruled out by this process .
We hope our process of investigation may shed some light on what it could or may not be.
Samples should be tested for the exact isotopes involved and also the mineral make up. If anyone finds new videos or reports of the “black stuff” please let us
