Fukushima prefectural gov shrank fallout survey / Still 10 Million Bq of Cs-134/137 emitted from Fukushima EVERY HOUR

Fukushima prefectural government announced that they decided to shrink the fallout survey from this April.

 

Having 10,000,000 Bq of Cesium-134/137 emitted from 4 crippled reactors every single hour, Fukushima prefectural government is going to survey the fallout in Fukushima city only in the rainy days. The reason wasn’t announced.

 

In Fukushima plant area, 2,900 MBq/km2 of Cesium-134/137 still falls down even based on Tepco’s own report.

Even this January, they measured the spike of fallout level in Fukushima city. The reading was 48.3 MBq/km2 (Cesium-134/137), which was the highest since 10/13/2013.

The situation is not stable at all.

La préfecture de Fukushima réduit sa surveillance des retombées / on y a toujours 10 millions de Bq de césium de Fukushima PAR HEURE

 

La préfecture de Fukushima a déclaré qu’ils avaient décidé de réduire leur surveillance des retombées à partir de ce mois d’avril.

La préfecture de Fukushima ne va plus surveiller les retombées sur la ville de Fukushima qu les jours de pluie alors qu’il y a toujours  10 000 000 Bq de césium 134/137 qui sortent des 4 réacteurs dévastés à chaque heure. La raison n’en a pas été donnée.

En ne se basant que sur les propres rapports de Tepco, dans la région de la centrale de Fukushima, 2,900 MBq/km² de césium 134/137 continuent toujours de retomber.
Même en janvier dernier, ils ont relevé un pic de retombées dans la ville de Fukushima. Le relevé était de 48,3 MBq/km² (césium 134/137), ce qui était un record depuis le 13 octobre 2013.
La situation n’est pas stabilisée.

  1. “Fukushima prefectural government is going to survey the fallout in Fukushima city only in the rainy days.”

    LOL..survey while its raining. Rain would knock down particles floating in the air and would give you better background numbers. Not to mention its safer for the guys giving the tests since all the particles are knocked down to the ground and are not being inhaled or getting stuck in a pore on your skin. You can bet they will be wearing rain coats on that day.

    So if the smart people knowing how bad it is to inhale these particles, would they be considered mass murders by giving you false data and telling you its safe to live there? All I see is a lame government not willing to relocate 500,000 people to the south.

  2. Nice Try,

    However, rain tends to INCREASE background radiation as well as anthropogenic nuclear fallout contamination. Torrential rain brings with it harmful natural radioisotopes such as radon, radium and tritium. Rainfall also concentrates and washes man-made radioisotopes such as Cesium-134, Cesium-137, Strontium-90 and man-made tritiated water.

    It is appropriate to measure the Fukushima Prefecture radiation conditions, rain and shine, day and night. And it is advisable to correlate the data to the weather conditions as one routine part of the analysis.

    Sincerely,

    Bill Duff

    1. That would seem true for ground measurements, but when would TEPCO ever weight the testing conditions against their advantage.

      I see them using a sensor mounted to the roof the vehicle, shielded from condensation, no doubt by using a small heating element. This would allow them to use a chimney to effectively only measure the radiation from the roof of the car.

  3. I would have thought wind direction (to/away from the plant) would also be a crucial factor. How does the wind direction correlate with the rainfall? If it rains more when the wind is from the west, the readings may miss the worst of the fallout.

    1. High winds, from any direction, probably stir up much higher Fukushima background radiation and nuclear fallout contamination, than what happens at the plant. Unless there is a major accident of some sort.

      A tornado, moving across plowed ground, would cause a major radiation release, in Fukushima.

      1. Yup.

        The surface contamination around the plant was up to 1 trillion Bq/km2.

        It’s hard to tell the difference between a new release from the plant and already contaminated dust being kicked up by the wind and redeposited.

      2. So the factors that contribute to ambient radiation levels are evidently quite complex. Wind increases ambient levels by stirring up dust. Rain would tend to dampen the dust, which by itself would presumably reduce the ambient level as measured (say) 1.5 metres above the ground. On the other hand, rain tends to wash down radionuclides from higher in the atmosphere, and tends to concentrate contamination in gutters, puddles, reservoirs etc. All this bears out Bill’s point that radiation needs to be measured continuously, in all weathers and in numerous locations. Moreover, a sudden spike in radiation levels in Fukushima City might be the first warning anyone gets that yet another balloon has gone up at the FD plant.

        1. Full Marks

          Yes, that is about the extent of it, for AIRBORNE nuclear fallout contamination for the 1,000 – 5,000 Square Miles surrounding the defunct Fukushima Nuclear Power Station.

          Similar complexities are ‘in play’ for the oceanic nuclear ‘washout’ and fallout contamination levels. Any disturbance of the seabed, from an earthquake, for example, will VASTLY increase the suspension of radionuclides and the background Gamma, Alpha, Beta and even Neutron levels.

          If it was easy, simple and cheap to clean up a nuclear power plant disaster, Chernobyl and Fukushima would be ‘Golden’.

          Mind-boggling complexity

    Cesium hotspots found in seabed east of Fukushima

    August 08, 2013, By SHUNSUKE KIMURA/ Staff Writer

    Radioactive cesium has formed hotspots on the seabed east of the Fukushima No. 1 nuclear power plant, the site of reactor meltdowns following the earthquake and tsunami disaster of March 2011, scientists said.

    Researchers from the University of Tokyo, the National Maritime Research Institute and other entities said Aug. 7 the hotspots are likely a result of highly radioactive water that leaked from the crippled nuclear plant in April and May 2011 and subsequently sank into seabed depressions. They say they are the first to have measured the distribution of radioactive substances on the seabed off the hobbled plant.

    “Like Green Starlight”: Highly contaminated ‘marine snow’ covered seafloor at least 2,000 kilometers from Fukushima by July 2011 (PHOTOS & VIDEO)

    Title: 1,200 Bq/Kg of Cs134 was detected in marine snow that was gathered from the depth of 5,000 meters of the Pacific Source: Tohoku Broadcasting, Author: guardianofmiyagi Date Aired: Sept 16, 2012, Date Published: Sept 29, 2012

    Marine snow like green starlight.

    A surprising result was reported by the Ocean Investigation Team. July 2011, investigation at the Kamchatka Peninsula offing depth of 5,000 meters. 1,200 Bq/Kg of Cs134 was detected in marine snow fathered from the deep sea.

    The radioactive contamination has reached the deep sea which is 2000 km distance from Fukushima Daiichi. It is considered that the origin of this Cs134 is not ocean currents but radioactive fallout and then reached the depth of 5,000 meters.

    1. Noting that Cesium’s high water solubility means that Cesium can exist anywhere in a water column.

      Unfortunately it also appears to pair off with hydroxyl ions (two of which constitute hydrogen peroxide), and increases acidity by lowering the logarithmic value known as “pH” (if i remember correctly).

      Also noting that sea spray can travel up to around 200 kilometers inland.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
