In wake of Japan confirming a nuclear meltdown at the Fukushima nuclear reactor, radiation levels have jumped to an all time high, maxing out instruments with readings over 1,000,000 microsieverts per hour.

I recently reported that there was a massive spike in radiation levels to over 700,000 microsieverts per hour at the Fukushima nuclear power plant following a fire that broke out at the plant.

MSM Fails To Cover 700 mSv Radiation Spike Following Massive Fukushima Fire

After every corporate media outlet in the nation ran major headline stories about a drop in radiation levels at the Fukushima nuclear power plant, they all fail to report huge spike in radiation levels up to 700 millisieverts per hour following a massive fire at the reactor in Japan.

Now, just days after Japan confirmed that a nuclear meltdown is underway at that the Fukushima #1 reactor, we have reports that the levels of radiation at the Fukushima reactor have spiked so high that they have maxed out the workers instruments which are capable of measuring levels up to 1/sv per hour or 1,000,000 (uSv) per hour.

#Fukushima I Nuke Plant: Radiation on 2nd Floor of Reactor 1 Exceeded 1,000 Millisieverts/Hour

Or more than 1 sievert/hour.

When 7 TEPCO employees and 2 NISA employees entered the Reactor 1 reactor building on early hours of May 9 (JST), the act that released mere 500 million becquerels of radioactive iodine and cesium into the atmosphere, they measured the radiation level on the ground floor which was 600 to 700 millisieverts/hour at the highest spot.

Then on May 10, someone went upstairs to the 2nd floor for the first time since March 11, and measured the radiation there. It was so high that the Geiger counter couldn’t accurately measure.

And TEPCO thinks the totally melted blob of fuel rods (uranium, plutonium) + cladding (zirconium alloy) + control rods (boron, cadmium, silver, indium) + stainless steel pipes + whatever was inside the Reactor Pressure Vessel = “corium” is being safely cooled at the bottom of the RPV.

From Mainichi Shinbun (5/11/2011):

Ministry of Economy, Trade and Industry’s Nuclear and Industrial Safety Agency (NISA) announced on May 11 that the radiation level exceeded 1,000 millisieverts/hour on the 2nd floor of the Reactor 1′s reactor building at Fukushima I Nuclear Power Plant. TEPCO has been preparing for the work to install the external cooling system inside the reactor building. This radiation level may be too high for workers to enter and work even for a short period of time. NISA’s spokesman Nishiyama said the high radiation “may affect the work to connect the pipes for the cooling system.”

The location that registered the high radiation level was near the valve of the emergency core cooling system. Measurement was done for 5 minutes starting 12:45PM on May 10 (JST), and at 1.6 meters from the floor the Geiger counter went overscale [and couldn’t measure beyond 1,000 millisieverts/hour].

The radiation level of 600 to 700 millisieverts/hour was detected on the 1st floor of the same reactor building on May 9.

There is also news that Japan believes that reactor 2 and reactor 3 are in a state of meltdown and that a pool of molten nuclear lava has formed at the bottom of the reactors and is burning through the reactor walls.
