Apparently, the radioactive radiations in the Fukushima Daiichi nuclear reactor, in Japan, were so high that a robot that was sent to locate and remove melted radioactive substances in the depth of one of Fukushima’s nuclear reactors, got shut off and was ultimately abandoned there. As per the reports, the radioactive radiations were 20 times higher than the expected.
This was the second robot, since last two weeks that met its end in the Fukushima nuclear power plant, the site where a major nuclear disaster occurred in 2011 which had caused a devastating earthquake and tsunami.

The robot was tasked to investigate the pedestal underneath of units 2 where the molten nuclear fuel was suspected to have fallen. But around 10 feet away from the target, the robot’s tank like treads got stuck and TEPCO (Tokyo Electric Power Company), which operates the power plant, decided to cut the robot’s cable, abandoning it inside the reactor.
The two-feet long scorpion-shaped robot that was assigned to investigate the nuclear plant had temperature and radiation sensors. It was also equipped with a camera on its tail that could whip up and look around.
According to the reports, this was one of the seven robots to have fallen in pursuit to investigate the nuclear matter which remains highly radioactive.
In a same case, last week too, a scouting robot was sent to scrutinize the matter, but it was pulled back because the camera installed on it got fried due to record high level of radiation estimated around 650 sievert per hour. A CT scan exposes one to 0.006 sieverts, and just half a sievert is enough to cause symptoms of radiation sickness.
