The Tokyo Olympic Games 2020 continue to belittle the aggravating consequenses of the Fukushima nuclear accident.
Recent frequent earthquakes in Fukushima and around make us worry about the collapsing of the unit 2 building
that could bring about another uncontrollable disaster.

Subject: Press Release: Radioactively-Hot Particles in Japan
New Study Shows Full Radiation Risks Are Not Recorded
PRESS RELEASE – 7/27/17
Today, the scientific journal Science of the Total Environment(STOTEN) published a peer-reviewed article entitled: Radioactively-hot particles detected in dusts and soils from Northern Japan by combination of gamma spectrometry, autoradiography, and SEM/EDS analysis and implications in radiation risk assessment. Co-authored by Dr. Marco Kaltofen, Worcester Polytechnic Institute (WPI), and Arnie Gundersen, Fairewinds Energy Education, the article details the analysis of radioactively hot particles collected in Japan following the Fukushima Dai-ichi meltdowns.
Based on 415 samples of radioactive dust from Japan, the USA, and Canada, the study identified a statistically meaningful number of samples that were considerably more radioactive than current radiation models anticipated. If ingested, these more radioactive particles increase the risk of suffering a future health problem.
“Measuring radioactive dust exposures can be like sitting by a fireplace,” Dr. Kaltofen said. “Near the fire you get a little warm, but once in a while the fire throws off a spark that can actually burn you.”
The same level of risk exists in Japan. While most people have an average level of risk, a few people get an extra spark from a hot particle.
According to Dr. Kaltofen, “The average radiation exposures we found in Japan matched-up nicely with other researchers. We weren’t trying to see just somebody’s theoretical average result. We looked at how people actually encounter radioactive dust in their real lives. Combining microanalytical methods with traditional health physics models,” he added, “we found that some people were breathing or ingesting enough radioactive dust to have a real increase in their risk of suffering a future health problem. This was especially true of children and younger people, who inhale or ingest proportionately more dust than adults.”
Fairewinds’ book Fukushima Dai-ichi: The Truth and the Way Forward was published in Japan by Shueisha Publishing, just prior to the one-year commemoration of the tsunami and meltdowns. “Our book,” Mr. Gundersen said, “which is a step-by-step factual account of the reactor meltdowns, was a best seller in Japan and enabled us to build amazing relations with people actually living in Japan, who are the source of the samples we analyzed. We measured things like house dusts, air filters, and even car floor mats. Collecting such accurate data shows the importance of citizen science, crowd sourcing, and the necessity of open, public domain data for accurate scientific analysis.”
Fairewinds Energy Education founder Maggie Gundersen said, “We are very thankful to the scientists and citizen scientists in Japan, who sought our assistance in collecting and analyzing this data. We will continue to support ongoing scientific projects examining how people in Japan and throughout the world experience radioactive dust in their daily lives.”
