Inside the Fukushima I Nuke Plant Reactor 2 Containment Vessel, 1/19/2012

TEPCO conducted the endoscopy of the Containment Vessel of Reactor 2 to see the inside. TEPCO's spokesman Matsumoto said in the press conference that the white specs in the video is from gamma rays. White streaks across the screen are water droplets.

The endoscope is made by Olympus. Drilling the hole on the Containment Vessel was done on January 17, requiring 40 workers in 10 teams. The endoscopy operation on January 19 took 34 workers, one hour, working right next to the Containment Vessel.

I have been reading on a popular energy website that the very drilling of this 'hole' for said endoscope has now created more problems with temperature fluctuations, is this true, and why would this happen.

[arevamirpal]

Temperature fluctuation started to happen in early February, before the hole was drilled for the endoscope.

If you watch any video of the Chernobyl disaster, the same thing happens. It's gamma rays overtaking and distorting the optics and also the metering sensors.

We have 500 more nuclear power plants. in the world. a couple more plants meltdown and the world is done. Then the rich might have to kill 6.5 billion instead of 6 billion. The oceans are polluted and it's all they can do producing seafood on land to keep up with demand.

This is what it must have looked like thru the eyes of Spock in Star Trek 2: The wrath of Khan.

More funny is that this amount of flashes is not real ammount of "gamma". There was gillion times more gamma than that. What we see are lucky chunks of photons that interfered due to the high doses even with sensor desighned for different "light".

If it would be ANALOG film, and higher doses, we would see unusuall "brightness" on it, just as sometimes happned in chernobyl (with most brightness coming from irradiated ground).

If it would be super deadly dose, even your naked eye would see that.

Ok, -finally-, about that red, blue, green, and white "noise" or "spark" flashes, occuring quickly.

In camera sensor, there are pixels, as many as is its resolution. Those are made of subpixels, each detecting red, green, or blue color. Combination of those subpixels (and their intensity) give final pixel.

Gamma, (unlike other radiation) - is on same principle as visible light, in extremely high concentration may variously overload subpixels, resulting in "fake" flashes of different colors.

thats fake i think eing that closewill cause u afast death

[Jonathan Calmett]

Ah man i'm getting cancer just looking at this video

[foxfox99112]

just about to say that haha

Neato....

Also notice how all of the flashes are either red, green, or blue (RGB).  This is due to sensor design limitations where specific sensor elements are filtered against 2 of the 3 colors and assigned a color. These subatomic particles are striking sensor elements without also striking adjacent elements for the other colors, resulting in color flashes of RGB.

[David Mattern]

Not so much overtaking and distorting the optics as registering directly on the CMOS or CCD sensor. Radiation was first discovered by its effects upon photographic film without involving exposure to light.

Shoryuken!!!
