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
ナノスケール純銀担持体の放射性セシウム減弱効果の検証測定 from 俊郎 浅学俊郎
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.
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.
