The evacuation orders of the most populated areas of Namie, Fukushima were lifted on March 31, 2017.

We are publishing the most recent soil surface density map of Namie created by a citizen’s measurement group named the “Fukuichi Area Environmental Radiation Monitoring Project“(http://www.f1-monitoring-project.jp/index.html). Their members are mainly from Tokyo metropolitan region.

Their map is simply terrifying. This is far much higher level of radio-contamination than in the Radiation Control Zone. Any area becomes designated as such when the total effective dose due to external radiation and that due to radioactive substances in the air is likely to exceed 1.3mSv per quarter – over a period of three months, or when the surface density is likely to exceed 40,000Bq/m2. In the Radiation Control Zone, it is prohibited to drink, eat or stay overnight. Even adults, including nuclear workers, are not allowed to stay more than 10 hours. To leave the zone, one…

Radioactive particles of uranium, thorium, radium, cesium, strontium, polonium, tellurium and americium are still afloat throughout Northern Japan more than six years after a tsunami slammed into the Fukushima Daiichi Power Plant causing three full-blown nuclear meltdowns. That was the conclusion reached by two of the world’s leading radiation experts after conducting an extensive five-year monitoring project.

Arnie Gundersen and Marco Kaltofen authored the peer reviewed study titled, 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, published July 27, 2017, in Science of the Total Environment (STOLEN).

Gundersen represents Fairewinds Associates and is a nuclear engineer, former power plant operator and industry executive, turned whistleblower, and was CNN’s play-by-play on-air expert during the 2011 meltdowns. Kaltofen, of the Worcester Polytechnic Institute (WPI), is a licensed civil engineer and is renowned as a…

This underwater robot was used in the recent probe of reactor 3 at the Fukushima No. 1 power plant.

The first images of melted fuel from the crippled Fukushima No. 1 power plant indicate that it did not burn through the pressure vessel of reactor 3, but exited through the holes used to insert the control rods, officials say.

While the landmark robot footage from the primary containment vessel of unit 3 is helping Tokyo Electric grasp the reality of the damaged fuel assemblies, it may also force it to rewrite the road map for decommissioning the meltdown-hit plant.

Tokyo Electric Power Company Holdings Inc., better known as Tepco, sent an underwater robot into reactor 3 earlier this month to confirm its hypothesis that the core — the fuel assemblies in the pressure vessel — broke apart and fell to the bottom, letting molten fuel burn through and drip into…
