Japan Fukushima Nuclear Reactor Radiation Levels Shoot to 100 Sieverts Per Hour


Radiation levels At Japan Fukushima Nuclear Reactor 1 have spiked to 100 sieverts per hour following earthquake aftershock and tsunami. This is far above the 100% lethal dosage of 6 sieverts per hour.

Radiation monitoring charts published by the Japanese government show that the radiation levels at Fukushima reactor number 1 have spiked to 100 sieverts per hour. It should be noted that it actual radiation could actually be higher because 100 sieverts per hour is the maximum that can be displayed on the chart.


Exposure to this level of radiation will cause immediate death. According to the NIH radiation levels of 4 sieverts per hour will cause fatality in 50% of people and at 6 sieverts per hour death is almost certain. 100 sieverts per hour is far above the 100% lethal dosage amount of 6 sieverts per hour.

The radiation spike came after an  earthquake cause to reactors at a separate nuclear power plant to start leaking radiation.

Radiation Leak in Japanese Onagawa Plant in Quake Aftermath

The earthquake also damaged the Onagawa Nuclear Power Plant, where a leak of radioactive water is reported by Japanese TV, citing the NPP operator Tokyo Electric Power. The leak comes from the pools where the used fuel of reactors one and two is stored, but no elevated levels of radiation have been recorded.

The shock was registered at 11:32 pm local time (5:32 pm Bulgarian time) and has an epicenter in the Pacific, 49-meters deep, according to the US Geological Survey.

Eyewitnesses say many buildings have been damaged; there are also reported fires and damage in the gas supply system; over 3.6 million households are without electric power.

There is no new damage discovered at the Fukushima NPP, which was badly struck by the devastating March 11 9-point magnitude on the Richter scale quake and following 10-meter tsunami.

Even with the increased radiation spike up to 100 sieverts per hour the Japan government still denies any new damage was caused by the  aftershock to the Fukushima power plant.

The plant operator says a strong aftershock on Thursday night did not damage any facilities of the compound, but the surface temperature of the Number 1 reactor rose sharply immediately after the tremor that hit northeastern Japan minutes before midnight.

The reading stood at 223 degrees Celsius at 7 PM, but it rose nearly 40 degrees just after the quake. The temperature had fallen back to 240 degrees at 6 AM on Saturday.

However, as we all know Japan has not been honest throughout this crisis. It should also be noted that The NY Times recently reported that the Fukushima reactors are very vulnerable to aftershocks at this point because the massive weight in the reactor pools caused by TEPCO trying to inject more water to cool the reactors.

True Horrors Of Japan Nuclear Disaster Revealed In Confidential Leaked Government Document

A leaked confidential NRC document on the Japan nuclear disaster reveals the situation in Fukushima is worse than anyone expected. Top scientists in the United States and Japan have discovered a “wide array” of “complex problems” warning that the Japan nuclear disaster could continue on indefinitely and things could start to get much, much worse at any minute. Perhaps the worse news is confirmation that radioactive fragments and particles, including the deadly Plutonium “MOX” fuel, has been shot high into the atmosphere during the hydrogen explosions.


Major Problems Found

Here is an overview of the major findings of the problems being faced revealed in confidential document.

  • Measures taken to keep the plant stable have created a wide array of problems.
  • The weight of the water injections have made the reactors vulnerable to ruptures during an aftershock.
  • The release of hydrogen mixed with seawater raises the possibility of the explosion.
  • The mixture of seawater with molten fuel is blocking fresh water from reaching and cooling the reactors.
  • New explosions could lead to further breaches in the containment vessels resulting in a much more serious release of radiation and leave a radioactive mass that would stay molten for a very long period of time.
  • Pouring water to cool the reactors may not be able to be sustained indefinitely
  • Fragments and particles of nuclear materials may have blown up to one mile high in the sky.
  • Radioactive material lying around the plant needed to be bulldozed over.
  • Because of the wide array of complex problems in three different reactors a successful outcome is less certain than ever.
  • Reactor 1 is likely fully blocked from new water entering to cool it and most likely has no water in it at all.
  • Similar problems exist in reactor 2 and 3 although blockage is less severe.
  • The spent fuel rods pose an even greater potential for damage then the reactors themselves.
  • The hydrogen explosion at reactor for is believed to released lots of radioactive material into the environment in what is termed as “a major term release”.
  • Spent fuel rods are being exposed directly to the environment as opposed to the reactors themselves which are still in their containment vessels.

To my knowledge there still has not been any official government acknowledgments or statements in regard to the massive radiation spike.
