[video=youtube;6LIu7bhRDXE]http://www.youtube.com/watch?v=6LIu7bhRDXE[/video] Up-close and personal view of the extraction and storage of fuel assemblies. Some pretty awesome footage of Cherenkov radiation inside a nuclear reactor used for power. Seeing how much light is emitted here when the reactor is shut down, one can only imagine how bright it might get inside a PWR running at normal levels.
Wow. I had no idea that radiation actually emitted light. I always thought that was a game/movie thing.

Very cool :zoid:
[QUOTE=awcmon;47345032]glow-in-the-dark watches and stuff in the early 1900's used radium[/QUOTE] This sucked for people back then, they used radium for a lot of stuff. [quote]The Radium Girls were female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint at the United States Radium factory in Orange, New Jersey, around 1917. The women, who had been told the paint was harmless, ingested deadly amounts of radium by licking their paintbrushes to give them a fine point; some also painted their fingernails and teeth with the glowing substance.[/quote] [url]http://en.wikipedia.org/wiki/Radium_Girls[/url]
[QUOTE=awcmon;47345032]glow-in-the-dark watches and stuff in the early 1900's used radium[/QUOTE] They glowed for a completely different reason.

[QUOTE=salty peanut v2;47345039]radiation is light. just not necessarily always visible light. sometimes??[/QUOTE] radiation isn't light it's more accurate to say that light is a form of moderate energy radiation
Radiation is a catch-all term. Light is radiation, but it is not all types of radiation. Radiation is always made up of particles, but they can be photons, electrons, atomic nuclei, and generally all sorts of particles. Specifically with Cherenkov radiation the glow is caused by an interaction of fast electrons (beta radiation) with the electrons in water which emits photons. Radiation can be distinguished by its energy level, but a more cut-and-dry method is to distinguish it by the type of particle it is. For instance radio waves, visible light, and gamma rays are all photons of different energy levels, whereas beta radiation is electrons. There are also certain compounds which will scintillate when it absorbs radiation, that is to say it will emit light. If I recall correctly radium-based lights employ something that scintillates when it absorbs the radiation from the radium mixed with it, and so it constantly glows.

You don't want to touch it

[QUOTE=Recurracy;47345865]enjoy becoming the world's first completely ionized man[/QUOTE] I wonder if it's possible for someone to become so radioactive they can actually kill the people they stand next to if they were somehow immune to the radiation.
[QUOTE=ultra_bright;47345930]I wonder if it's possible for someone to become so radioactive they can actually kill the people they stand next to if they were somehow immune to the radiation.[/QUOTE] Well if you were immune to the negative effects of radiation (which is virtually impossible but lets imagine it is possible) and then you were exposed to very high levels of neutron radiation for long enough, the atoms in your body could become radioactive from neutron capture. Im guessing that if enough atoms captured enough neutrons to become radioactive, you could become radioactive enough to induce radiation poisoning by standing next to someone. Of course in the real world you would just die from radiation exposure long before you became dangerous to other people. Some more footage from inside a reactor core [video=youtube;aZudXS6QwaY]http://www.youtube.com/watch?v=aZudXS6QwaY[/video] One thing I am curious about is that red-orange tarnish that seems to be covering everything.
[QUOTE=ultra_bright;47345855]I'm going to touch it and you can't stop me.[/QUOTE]He can't, but the radiation will before you get close enough. Very unique form of suicide though.

[QUOTE=mecaguy03;47346212] One thing I am curious about is that red-orange tarnish that seems to be covering everything.[/QUOTE] My guess is that while normally stainless steel used in the reactor doesn't rust, the massive neutron fluxes inside the reactor knock iron ions out of the metal where it turns to iron oxide. [editline]18th March 2015[/editline] That weld near the end of the video is fucking shoddy looking.

are there any videos from unshielded cameras? would be cool to see some of that white noise effect
[QUOTE=Em See;47347251]are there any videos from unshielded cameras? would be cool to see some of that white noise effect[/QUOTE] Even on the shielded camera there seems to be a bit of it.
[QUOTE=Em See;47347251]are there any videos from unshielded cameras? would be cool to see some of that white noise effect[/QUOTE] Chernobyl footage has a lot of grain and white noise from the fuckloads of radiation emitted.

What kinds of degrees are in-demand at nuclear power plants?
[QUOTE=Del91;47345923]Nuclear Reactor start up: [url]http://youtu.be/7eHkpUSaVwU[/url] Neat I'm too lazy to convert the mobile link to full[/QUOTE] Whoa. That is insanely cool. How does one start a nuclear reactor? Obviously the control rods can't be in place and prohibiting a reaction, but do you need to generate a burst of neutrons or will the fuel start the reaction on it's own?
