A detailed explanation of what has happened at the Fukushima nuclear power plant

Check out this detailed engineering explanation of what has happened, is happening, and will happen at the Fukushima nuclear power plant in Japan. Key quote:

The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is โ€œliquid control rodโ€. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.

TSA to retest airport body scanners for radiation

Does this make you feel safer? The TSA is going to retest the radiation levels of all its airport body scanners after maintenance records on some showed levels 10 times higher than expected. Also this:

The TSA is responsible for the safety of its own X-ray devices. The U.S. Food and Drug Administration has said it does not routinely inspect airport X-ray machines because they are not considered medical devices. The TSA’s airport scanners are exempt from state radiation inspections because they belong to a federal agency.

David Horowitz Takes on Muslim Students at Brooklyn College

So who are the real hate-mongers here? David Horowitz speaks at Brooklyn College while under heavy security. To me, the key quote is this:

Mr. Horowitz began by ruefully observing, โ€œWhen I went to college you didnโ€™t need all of this security on campus, but things have changed and thatโ€™s the reason we now need checkpoints on campuses. Checkpoints are essential to defend against terrorists and Jew haters.โ€ Adding that he has been verbally and physically assaulted on campuses around the country for his forthright views, he said, โ€œOur campuses are controlled by liberal fascists and it is a movement to suppress the free speech rights of conservatives.”
