Nano Silver

I report the most interesting experiment result in the above presentations in this article.
Dr. Abe and Dr. Iwasaki had been announced the experimental results that the radiation of the contaminated soil was reduced when they added nano sliver solutions to the soil. This presentation showed the new experiment that nano silver particles could decrease radiation of radioactive potassium (K40).

I think this result is very important in the following points.

  • Radioactivity decreasing effect of 4-5 nm silver particles was effective for K40 other than radioactive Cs. I think they expected the effect because they have found radioactivity decreasing effect for both Cs137 and Cs134.
  • Potassium fertilizer used in the experiment can be purchased by anyone. The key material, 4-5 nm silver particles, is shipped by UFS-REFINE company. Therefore, I expect reproduction of the experiment will become much easier.
    (If anyone wants to

My summary of presentation material for the oral presentation by Dr. Iwasaki is shown below.

  • K40 is radioactive material present in nature, 0.01% abundance ratio, T1/2 = 12 billion years.
  • Because the sensitivity of spectrometer (Clear Pulse Co., A2702) is low, a large amount of potassium fertilizer is required, then they filled U9 type standard container with Potassium fertilizer (76.7g).
  • As the first position (“up” position), they put the spectrometer horizontally at the bottom of the lead shielding box and put the U9 container on the spectrometer. As the second position (“down” position), they put the U9 container horizontally at the bottom of the lead shielding box and put the spectrometer on the U9 container. They regarded two measurements, up and down positions (each measurement takes 12 hours), as one unit and calculate the average of result values.
  • They started Series I experiment from February 12, 2013. After the initial measurement, they opened the container to check the content, and transferred the content to the tray. Then, they added 5 g of Talc powder supporting nano silver particles (300 ppm) to the content and stirred it. And they added 10 cc of collagen solution supporting nano silver particles (160 ppm) to the content and stirred it carefully. After the process, they returned the content in the U9 container and sealed the joint part of the lid by tape. They did 8 units of measurements until August 9. For the measurements, they also measured background radiation many times.
    (They watered UFS-CW20F to get suitable density (160 ppm) as collagen solution supporting nano silver particles.)
  • Because in the 8 units of measurements, they missed the down position measurements in 2 times, they showed the 6 units results. Each figure shows relative ratio to the initial radiation value. Each radiation value is calculated as
    [total number of photoelectric peak area of K40] – [background].

Feb 13 up, Feb 14 down (initial value):     1.00
Feb 15 up, Feb 16 down:     0.83
Feb 17 up, Feb 18 down:     0.87
Apr 8 up, Apr 9 down:     0.81
May 5 up, May 6 down:     0.79
Jun 27 up, Jun 27 down:     0.80
Jul 24 up, Jul 25 down:     0.77
Aug 9 up, Aug 9 down:     0.80

  • As the result, the decreasing ratio is about 20%. The estimated uncertainty of the average value taking into account the “up / down” difference is about 3% to 12% and the statistical uncertainty is under 2.5%.
  • On September 10, they opened the U9 container to check the content and injected 5cc of collagen solution supporting nano silver particles (20ppm) to the center of the content. From one day later, they started Series II measurements and they are going now. They obtain the similar result in the Series II.
  • In conclusion, they can set the hypothesis that 4-5 nm silver particles can decrease the radioactivity of K40, too.

I expect that other scientists will reproduce the experiment and find new technology to reduce radioactivity of huge volume of nuclear waste.

LENT of radioactive materials by super vibration

In Japan, Fukushima Daiichi Nuclear Plant is continuing to generate radioactively contaminated water and leak it out.   On September 10, 2013, the Ministerial Meeting on Contaminated Water and Decommissioning Issues discussed “Policies and Concrete Actions for Addressing the Contaminated Water and Decommissioning Issues”, and concluded that a team to collect expertise from all over the world and to invite proposals of countermeasures would be established.  (The detail is here in English.)

The issued Request for Information (RFI) was closed on October 23.  The overview of result of RFI is here in English.  The number of proposals submitted is 779 and they are published as PDF files in here in Japanese.  (Some proposals from overseas are written in English.)

A few proposals seem to be based on LENR or LENT (Low Energy Nuclear Transmutation).  For example, Dr. Shin Iwasaki proposed LENT technology by nano silver particles (No.210 and No.211) which I have introduced at here.

Another LENT technology described in No.396 (in Japanese) is very interesting and may attract LENR watchers’ attention.  This is proposed by JAPAN TECHNO CO., LTD.  The company is famous for OHMASA-GAS that is very stable and easy storable oxygen and hydrogen mixed gas.  OHMASA-GAS was featured in NHK WORLD NEWSLINE as here.

OHMASA-GAS is generated by electrolysis while the water is being stirred by “super vibration” wings.  No.396 is related with the super vibration in water but not related with OHMASA-GAS itself.

JAPAN TECHNO claims that the super vibration in water generates many nano bubbles which cause nuclear transmutation.  As the result, radioactive materials, for example radioactive cesium, are transmuted to non-radioactive materials.  While the paper of No.396 does not describe detail, Dr. Ryushin Ohmasa, the president of JAPAN TECHNO, seems to be very confident because he got the result of elementary analysis of contaminated water before and after the super vibration when I talked to him.

In this context, a very interesting patent application was applied on July 27, 2007 in Japan by Dr. Ohmasa.  (The Japanese patent application is published here.)

In the application, Dr. Ohmasa claimed that over 100 Hz vibration to water for over 100 hour caused increase of Mg, Zn, Ca, Al, Cu, Na, K and Se in the water.  The following table shows the result of ICP Mass Spectrometry of pure water before and after the vibration in 200 hours.

This phenomenon is very interesting and one of hopes that can decontaminate huge radioactive water.  I hope the committee will study seriously the phenomenon and technology.

Decontamination of radioactive ashes by nano silver

This is the 3rd report about the decontamination by nano silver which may be LENR transmutation.

In Japan, city garbage is gathered by trucks and taken to the incinerator plant everyday. In the plant, the garbage is burned and the ashes are buried into landfills. That was before March 11, 2011, the disaster of Fukushima Daiichi Nuclear Plant.

The 2nd incinerator plant of Kashiwa city in Japan.

After the disaster, at some incinerator plants, the radioactivity of the ashes is very high and exceeds the limit for land reclamation. As the volume of the ashes is about 1-10% of the original garbage, the radioactive materials are concentrated. The highly-radioactive ashes are packed into containers and moved to a temporary warehouse.  

For example, in the second incinerator plant of Kashiwa city in Japan, 57.60 tons of radioactive ashes were moved to a temporary warehouse in April of 2013, as below (this data is published at here ).

On March 28, 2012 from 9:30 am to 11:45 am, Dr. Norio Abe, Chief of Itabashi Firefly Ecosystem Center, went to the plant and conducted an experiment that would decontaminate the ashes using nano-silver.

A report on the experiment is shown in SlideShare ( here ).  I added English terms beside the Japanese terms. Figures in the report are not as clear in the embedded view of SlideShare, so please download the PDF document from SlideShare if you have trouble reading it.

Abstract of the experiment:

  • 12Kg of the ashes were moved to 3 pails ( Each pail had 12Kg of the ashes) 
  • The team prepared 3 types of materials.  They mixed each material for each pail and measured radioactive level just after mixing and after 30 min ( or 25 min ).
  • The 3 types of materials:
    (A) 3.6 liter of tap water  ( for controlled experiment )
    (B)  3 liter of nano silver embedded collagen (10ppm) and 3 Kg of nano silver embedded boan coal
    (C)  3 liter of nano silver embedded collagen (20ppm) and 3 Kg of nano silver embedded boan coal
    (The difference between B and C is the density of nano silver embedded collagen — 10 ppm vs 20 ppm)
  • As the result, in the cases of B and C, the level of radioactivity of the ashed decreased.  For example, in the case of C, the level was 6.12 μSV before mixing and decreased to 4.00 μSV just after mixing. The level after 30 min was similar to the level just after mixing.

Unfortunately, they had to end the experiment after 30 min of mixing due to time limitations.  I speculate that the level of radioactivity might be decreased further by additional stirring of ashes, because in the experiment (here) reported at the conference of “radiation detectors and their uses”, a decrease after stirring is shown.

Anyway, I think this experiment shows the possibility of transmutation from radioactive material into a non-radioactive one.  I hope other researchers will try and re-produce this experiment.

Field work of Cesium decontamination by nano silver

On December 10, 2011, Dr. Norio Abe did a radioactive cesium decontamination experiment by the nano silver at an kindergarden in Koriyama city of Fukushima prefecture in Japan. Dr. Abe sent me the result data, then I try to make a summary of the experiment.

1. Outline of the experiment

On December 10, 2011, at an kindergarden in Koriyama city, Dr. Abe did the experiment at the same time as the water washing of the roof for decontamination.  He used the filtration device called “Lucy”, that has four stages of filtration including nano silver supported by bone charcoal and white granite.

He filtered cesium contaminated water three times by Lucy.  Each time the value of radioactivity of the filtered water was measured using a germanium detector by a professional company.

As a result, the radioactivity of the water was reduced to 1/10 as compared to the initial value.  Furthermore, he measured the radioactivity of the used filter in 8 days at Itabashi Firefly Ecosystem Center, and it was reduced to less than 50%, too.

3. Experimental results

The following values indicate decontamination level of the water (Bq / L) after the three times filtering.

(Bq/L) Initial 1st time 2nd time 3rd time
Cs-134 13300 1840 1350 1340
Cs-137 18800 2490 1910 1830

 



After the experiment, he carried Lucy to Itabashi Firefly Ecosystem Center and measured the radioactivity of the filter.  The following values indicate the radioactivity of the bone charcoal and white granite including nano silver.

.

The measurement started at December 11, while the experiment was done on December 10, then the initial value of radioactivity might be higher than 0.56 μSv/H. Further, as the background radioactivity was not measured, the background value was not subtracted.

The result is very impressive because it seems to show nano silver can decontaminate the radioactivity of Cesium in a real situation.  I hope other scientists may pay attention to the experiment and will try to reproduce these results.

Nanoscale Ag may decrease radiation of Cesium 134 and 137 through LENR transmutation? Toshiro Sengaku

Nanoscale Ag may decrease radiation of Cesium 134 and 137 by LENR transmutation?

On  the week of Feb 5, the conference of “radiation detectors and their uses” was held in High Energy Accelerator Research Organization in Tsukuba city of Japan.  Japanese web site is (here) and Google translated one is (here).

In the conference, there was a very interesting presentation “Experiment and verification of the radioactive cesium decrease effect of nanoscale pure silver (Ag) with supporting material” for LENR watchers.  (This title is translated to English by me and may be inaccurate.)

The Japanese abstract (PDF document) was published (here) and p.69 and p.70 are for the presentation.

Experiment and verification of the radioactive cesium decrease effect of nanoscale pure silver (Ag) with supporting material

The author, Dr. Shin Iwasaki, a physicist and ex-professor of Tohoku University of Japan, describes the results of some experiments that the nanoscale Ag supported by bone charcoal and white granite or collagen liquid can decrease the radioactivity of the radioactive cesium in Fukushima prefecture of Japan in the laboratory.

In Fukushima, after the Fukushima Daiichi nuclear disaster of March 11, 2011, the soil and many houses were contaminated by radioactive cesium. To decontaminate, people had to wash roofs and walls by water, and remove the surface-soil containing the radioactive material.  The big problem is how to treat the washing water or removed soil, because we have no way to decrease the radioactivity.

Dr. Norio Abe, a biologist and the chief of Itabashi Firefly Ecosystem Center in Tokyo, thought of the idea to use nanoscale silver Ag to decontaminate radioactive soil because he had well-known the capability of nanoscale Ag to keep the environment clean for the firefly.  

Surprisingly, the radioactivity of the soil decreased after he had spread nanoscale Ag with collagen liquid.

While the reason or mechanism is unknown, he succeeded to decrease the radioactivity of contaminated water or soil in several fields in Fukushima.

In March 2012, Dr. Shin Iwasaki joined the group with Dr. Norio Abe and started to help verify the strange phenomenon.  Then in Nov 2012, after much trial and error, he was able to measure the effect. In the abstract, the main result is shown in Fig. 1.

He made the sample in U9-type container by combining the 4-5 nanometer Ag with bone charcoal and washing with water including Cesium.  He measured radioactivity by monitoring the gamma spectrum over a long period using Csl (T1) detector + 512ch MCA.  He said that his team payed attention to uniformity of the sample, self shielding, volatilization and location of the measuring instruments.  

While the natural half-life of Cs-134 is 2 years, and one of Cs-137 is 30 years, Dr. Iwasaki analysed the experiment and concluded there was a decrease in the “half-life” of radioactivity of these Cesium isotopes to about 1 or 2 months.

The graph of Fig. 1 shows the time series of the relative values of radioactivity to the original sample without nanoscale Ag.  For example,  “1.0” is the value of the original sample and “0.6” means the value is 60% of the original sample.  3P and LC shows the following values and the background radioactivity is reduced.

3P: sum of 3 peaks including 604keV of Cs-134, 661.6keV of Cs-137 and 795.7keV of Cs-134 and others.

LC: sum of continuous values under the 3 peaks.

Nano-silver-Fig-1

This experiment started at Dec 22, 2012 and ended at Jan 16, 2013.  In the first few days, the half-life of the radioactivity is equal to about 20 days,  He added 0.6 cc pure water to the sample and stirred at Jan 14, 2013 and the value started to decrease again.

This result is very impressive for me because the experimental system is simple and the effect is big. Dr. Shin Iwasaki suggested the phenomenon may be one kind of LENR.

Unfortunately, this project has little budget, and he can not analyze the mix of elements of the used sample.  In the abstract, he calls for other scientists to reproduce this experiment.  I hope they will too.  This phenomenon may help to decontaminate water and soil around the Fukushima Daiichi nuclear plant.
