  • Japan - Extreme Radiation Levels Detected At Fukushima Reactor, Highest Since 2011

    FEB 3, 2017

    The level of nuclear radiation detected at the troubled Fukushima nuclear plant in Japan spiked on Thursday to its highest level since the triple core meltdown in 2011.

    In March 2011, multiple reactors at the Fukushima Daiichi power plant spiraled out of control after a 42-foot tsunami overwhelmed the plant’s sea walls, rendering the vital systems used to cool the plant’s six reactors inoperable.

    Ultimately, fuel meltdowns occurred at three reactors, releasing vast amounts of radioactive matter and resulting in the world’s worst nuclear disaster since Chernobyl.


    On Thursday, the Tokyo Electric Power Company (TEPCO), the investor owned utility that operates the Fukushima reactors, reported that it detected a radiation level of 530 sieverts per hour in the containment vessel of reactor 2 at the Fukushima No. 1 power plant.

    A sievert is a measure of the health effect of low levels of ionizing radiation on the human body.

    Even a brief exposure to 530 sieverts of radiation would kill a person. Exposure to only one sievert is enough to result in infertility, loss of hair and cataracts. According to the National Institute of Radiological Sciences, exposure to a mere four sieverts of radiation would typically be lethal for one out of every two people.

    The highest level of radiation detected previously at the Fukushima reactor was 73 sieverts per hour.

    Highest radiation reading since 3/11 detected at Fukushima No. 1 reactor

    Tepco also announced that, based on its analysis of images taken by a remote-controlled camera, that there is a 2-meter hole in the metal grating under the pressure vessel in the reactor’s primary containment vessel. It also thinks part of the grating is warped.
    The hole could have been caused when the fuel escaped the pressure vessel after the mega-quake and massive tsunami triggered a station blackout that crippled the plant’s ability to cool the reactors.
    The searing radiation level, described by some experts as “unimaginable,” far exceeds the previous high of 73 sieverts per hour at the reactor...

      A Dutch expert says: the radiation level did not go up, the level was high all the time. Now with a new robot camera they could go deeper in the reactor and do new measurements.
