The video shows the outer containment building blew up do to an apparent hydrogen explosion. The inner reactor vessel evidently remains intact.
All talk of radioactivity is pointless UNLESS you point out the element and the actual radioactive yardstick of said material. Half-life is not a good measurement. Some isotopes have long half lives but are essentially harmless. You would get more exposure from the sun.
Chernobyl's reactor was an air cooled graphite reactor. A really bad design to begin with. Nothing in common with Japan's reactor designs.
I always suggest to someone interested in the subject of nuclear power to read Dr. James Mahaffey’s “Atomic Awakening” as a great primer for combating the lies and misrepresentations.
Here is a trivia question for you all:
The most irradiated spot on Earth is? Hint: It's total exposure equaled a full scale thermonuclear exchange.
Here is another hint: It is a lot closer to CNN than they would think :-)
The reactor that had an explosion and has suffered a partial meltdown was built by GE. Its steam generation system was also built by GE. Many moons ago.
“The most irradiated spot on Earth is?”
Chelyabinsk...
With the Oak Ridge processing buildings not far behind...
