Video from a robot climbing into the Fukushima reactor
The robot that died heroically in the depths of the Fukushima-1 power unit, which I wrote about the day before yesterday , still managed to make a video. For some reason, the Japanese have not installed a good quality video camera in the robot, but you can see what is happening there.
Inside the reactor there seems to be some kind of debris and steam is constantly flowing. The built-in dosimeter shows the level of radiation, and at some point it reaches 24 Sv / h ( sievert per hour). At the same time, a person from natural sources (cosmic rays, soil, water) receives no more than 10 mSv per year. A dose of 3–5 Sv causes radiation sickness and damage to the bone marrow.
Experts estimate the time to completely eliminate the consequences of the accident at 40 years. At the same time, there are no reliable and proven technologies for quality cleaning of contaminated areas. Perhaps the recent discovery of the binding of radionuclides by graphene oxide will help in this complex matter.
