Ultra-high concentrations of radioactivity that could kill humans in an hour have been detected in Fukushima, Japan.
On the 26th, Japanese media such as the Yomiuri Newspaper and the Mainichi Newspaper reported the contents of the interim report on the investigation of the accident at the Fukushima No. 1 nuclear power plant, which was released by the Review Committee under the Nuclear Regulatory Commission.
According to the report, it is estimated that there are facilities with extremely high radiation levels near the 5th floor of the nuclear power plant’s 2nd and 3rd reactor buildings. This is a circular reinforced concrete triple structure facility’shield plug’ that acts as a’cover’ for a reactor containment vessel, and it appears to have been contaminated with radioactive materials.
The review committee differs from the 2nd to 4th becquerel (a unit that measures the amount of radiation emitted by a substance) due to a nuclear accident on the shield plug of the nuclear reactor of Unit 2, and the cesium 137 of about 3 becquerel is different from the shield plug of the reactor of Unit 3. I saw it as attached.
Local media say that when converting this into the amount of radiation exposed to the human body, It exceeds a maximum of 10 sieverts per hour (Sv), so “a life can be lost in an hour”Explained.
On the 27th, in MBC news reports, an internal video of the Fukushima No. 1 nuclear power plant was reported by the investigation team to decommission the nuclear reactor last year. Reportedly, the inside of the nuclear power plant was difficult to enter because debris collapsed by the hydrogen explosion was piled up. Also, sooner or later, a loud beep starts to sound from the machine warning of the amount of exposure.
The investigation team immediately ran away, shouting, “It’s dangerous, wait.”
When an investigation into the radiation dose that could kill a person within an hour came out, even the nuclear regulatory committee officials stuck their tongue out. He said, “I expected a large amount of cesium, but I didn’t expect the pollution to be concentrated at this level,” he said, saying he was embarrassed.
In addition, Toyoshi Fuketa, chairman of the Japan Atomic Energy Regulatory Commission, said, “I think the impact on the decommissioning operation will be very great in the future. The shielding method is also quite difficult, and it is unlikely that it can be done completely remotely.”
The Regulatory Commission plans to release a final report containing the results of the Fukushima nuclear accident investigation in March.
