The Japanese have a serious problem with a nuclear reactor complex impacting four nuclear reactors. Several workers have suffered from radiation burns and radiation overexposure remains a big threat. The main strategy they have seems to be hosing sea water on the reactors or dumping it from the air.

The Japanese are known for the world's most sophisticated robots. They have robots that can catch tennis balls thrown at them, robots that can play the piano and even robots that can run a marathon.

Why are they not using robots? How difficult can it be to hook up a camera to a robot and control it remotely? How difficult can it be to, say, pick up an exposed spent fuel rod and immerse it in water?

Obviously they would have done it by now if it was an option. So it isn't an option. Why?

You need to understand Japanese culture and how they allocate funding to robotics research. Robots that can remotely tackle nuclear disasters are all very worthy, but do they produce authentically soiled underwear you may sniff?

I think the Japanese are leaking the radiation on purpose because they want to create a giant radiative octopus so they can live out their dreams of anime tentacle rape. Either that or they're trying to really create Godzilla. :p

Ionizing radiation can cause semiconductors to fail after only relatively low doses of radiation.

P.S. I'm sorry I made you learn something :(

I guess if the repair work required a stationary robot that could catch a tennis ball, the ability to play the piano or the ability to run a marathon, they could use them.

Shame they didn't build a fix the nuclear reactor robot!

That's actually a serious answer, robotics is still in the area of producing very specialised robots, this is likely to be highly complex work involving high levels of adaptive intelligence and many complex motor skills, we're a long way away from any robots being able to do that.

And they are crap at getting up if they fall over.

It's a great design. Huge hands, so that you can catch all the radiations before they hit your face.

If JNo Mojinpoklm still posted here, he'd back me up on that.

Lead can reduce gamma particles, it depends how energetic they are how much lead you need, and some will probably still get through.

How much useful work do you think you could do wearing a suit of lead several centimetres thick?

Alpha particles can get stopped by a sheet of paper. Not such a big deal.

I think our university gamma source had about 6 inches of lead shielding at the thinnest point.

Still waiting on the super strength, healing powers, and anger management problems to develop, btw.

I was thinking about protecting just the abovementioned semiconductor chips.

Just the robot "brains" needs to be protected, robot "limbs" don't. They can be as nimble as they come, especially if remote-controlled (e.g. remote surgery). Provided the radiation doesn't disturb the controlling signal too much.

Japan a robot power everywhere except at nuclear plant
By Jon Herskovitz, Agence France-Presse March 17, 2011 Comments (4)

TOKYO - Japan may build robots to play the violin, run marathons and preside over weddings, but it has not deployed any of the machines to help repair its crippled reactors.


While robots are commonplace in the nuclear power industry, with EU engineers building one that can climb walls through radioactive fields, the electric power company running Japan’s Fukushima Dai-ichi plant has not deployed any for the nuclear emergency.


Instead, its skeleton team has been given the unenviable and perhaps deadly task of cooling reactors and spent nuclear fuel on their own, only taking breaks to avoid over-exposure.


A science ministry official said a robot used to detect radiation levels is at the site of the accident in Fukushima, north of Tokyo, but nuclear safety agency official Hidehiko Nishiyama said: "We have no reports of any robots being used."


That robot would have come in handy early on Thursday when workers monitoring radiation had to back away from the plant because it was becoming too hot.


While Japan is renowned for its cutting edge technology, it also maintains an anachronistic element in its society that relies on humans for tasks that have given way to automation in many other parts of the world, such as operating elevators and warning motorists of road construction.


In one of Japan’s worst nuclear accidents, two workers were killed in September 1999, when workers at a nuclear facility in Tokaimura, northeast of Tokyo, set off an uncontrolled nuclear chain reaction by using buckets to mix nuclear fuel in a lab.


Japan is a world leader in robots, using them to automate the most complicated manufacturing processes and to sift through rubble to look for victims in earthquakes.


Robots were also used after two infamous nuclear disasters - Three Mile Island and Chernobyl, and will almost certainly be used at Fukushima for work in highly radioactive areas.


Kim Seungho, a nuclear official who engineered robots for South Korea’s atomic power plants, said: "You have to design emergency robots for plants when they are being built so they can navigate corridors, steps and close valves."


The Fukushima plant was built in the 1970s, well before robots were able to work on sophisticated tasks.


Robots are in place in many nuclear plants for structured situations such as monitoring pipes and simple maintenance.


Kim, a deputy director in nuclear technology for the Korea Atomic Energy Research Institute, said budget constraints and denial have kept emergency robots out of many plants in his country and around the world.


"Nuclear plant operators don’t liked to think about serious situations that are beyond human control," he said by telephone.

So they researched Atomic Theory ahead of Robotics. A mistake that I have made myself many times.
