[b]The first footage from inside one of Japan's tsunami-hit nuclear reactors at Fukushima has been released by the stricken plant's operator.[/b]
[quote]Tokyo Electric Power Company (Tepco) inserted an endoscope camera in Number 2 reactor to examine the interior.
Thursday's probe aimed to get details such as the true level of cooling water and temperature inside the vessel.
The six-reactor Fukushima Daiichi nuclear plant was badly damaged by the 11 March earthquake and tsunami.
Last month it was announced that the nuclear reactors had finally been stabilised and reached a state of "cold shutdown".
This occurs when the water that cools nuclear fuel rods remains below boiling point, meaning that the fuel cannot reheat.
Radiation distorted footage
The video probe, just 8.5 mm in diameter according to one report, was inserted into the vessel to ascertain reactor conditions, particularly the level of cooling water and the temperature.
Some of the footage was distorted because of the levels of radiation, but officials say no major ruptures caused by the earthquake have been spotted.
"The visual artefacts provoked by the high level of radiation and other leaks inside are a viewing obstacle, but nevertheless the images are of relatively good quality in some areas," Tepco official Junichi Matsumoto is quoted as saying by the Associated Press news agency.
Tepco also said that experts were still trying to identify all the parts that were shown in the video.
The probe failed to find the water surface, which indicates that it sat at lower than expected levels and raised questions about the accuracy of current water monitors.
But the probe confirmed that the temperature inside the reactor was in line with the temperature gauge outside the container.
The information from the probe "will help us keep the reactor stable and solve problems," Ms Matsumoto is quoted by Reuters as saying.
Reports say that Tepco now hopes to use the endoscope to look inside two other stricken reactors but officials say radiation levels would have to decrease before that can happen.
A 20km (12m) exclusion zone remains in place around the plant. The government says it will take decades to dismantle the plant completely.
More than 80,000 people had to leave the area. Radiation levels in some places remain too high for them to return home.[/quote]

Its amazing how much damage these incidents have caused, yet most people just heard it and assumes it was over after a month.
Noone here, but the general populace of everywhere except japan.
What's falling? Looks kinda like dirty water.
It's distortion caused by the level of nuclear.
Heres some photos of their "wasteland" [url]http://www.adelaidenow.com.au/news/galleries/gallery-e6frecgc-1226231557916?page=1[/url]

Jesus, that distortion is insane. It's creepy to think that the radiation levels are at such high levels that they can cause this.

The distortion is merely the visual artifacts - the "noise" you can see. The things flying past are probably water droplets.

The noise is high ISO
As depressing as this disaster was, The plant and the surrounding area are really cool looking.
The article says the artefacts (lolstalker) are caused by the radiation.
I don't understand how that could be, it's an endoscope camera, if the actual receptor was taking that much radiation, the operator would be dead.

Because the sensor is what actually captures the image, and that's what is in the reactor.

Also, the distortion is most definitely because of the radiation. It is known that radioactive energy will seriously influence image capture; it isn't just high ISO.

But it's an endoscope, not a regular camera.

So the sensor isn't in the reactor, just the tip of the fibre-optics.
The sensor is with the operator.

Radiation does not act that way around optical fibers (if you meant it was going up the fiber optic line and to the CCD). More than likely it's reaching the CCD simply by passing through the camera housing and striking the CCD in the way past.
The noise though is incredible. I only saw this once before on a random reel of film from the Chernobyl incident.

But if it's reaching the CCD (that's the term right?) and causing that much interference, the operator wouldn't be feeling very healthy right?

[QUOTE=ExplodingGuy;34308408]The radiation still travels up the fiber into the CCD.[/QUOTE]
No it doesn't.
If you could redirect nuclear radiation with fibre optics do you think it'd be such a big issue?
ITT: people who know nothing about radiation.
The distortion gets progressively worse as it gets closer to the radiation source.
wow, my school has bbc.uk blocked... are you fucking serious
yes, the disortion is caused by the radioactivity
