How Two Women Made Your Watch Glow in the Dark

On December 21, 1898, Marie and Pierre Curie discovered the radioactive element radium (in the form of radium chloride), extracting it from uraninite. They first removed the uranium from the uraninite sample and then found that the remaining matter was still radioactive, so investigated further. Along with the barium… » 6/13/14 5:15am 6/13/14 5:15am

The EPA Just Made NYC's Most Radioactive Place Into a Superfund Site

Yesterday, we enjoyed The New Yorker's engrossing interactive look at the strange history of NYC's most radioactive place, an auto shop in Queens that occupies a former factory that produced radioactive thorium for the Atomic Energy Commission. Today, after months of study, the Environmental Protection Agency decided… » 5/08/14 2:20pm 5/08/14 2:20pm

Like so many NYC businesses, Primo Flat Fix occupies a nearly 100-year-old building. But this Queens, garage sits on a very peculiar piece of dirt: The former site of Wolff-Alport Chemical Company, a rare-earth supplier that furnished the Atomic Energy Commission with radioactive thorium—when it wasn't dumping the… » 5/07/14 12:40pm 5/07/14 12:40pm

Radioactive Iodine Levels Near Fukishima Plant Are 1250 Times Higher…

Radioactivity levels have spiked in seawater just offshore the Fukushima Daiichi plant. Tests have found that the radioactivity is 1,250 times higher than normal with radioactive water being found in 3 of the 6 reactors. Three workers have actually sustained burns after being exposed to the radiation. [Reuters] » 3/26/11 11:32am 3/26/11 11:32am

Networked Geiger-Counter Cellphone System to Detect Radioactive Bombs

This anti-terrorism concept from researchers at Purdue University puts together miniature radiation counters built right into cellphones across the US. Each solid-state sensor would be able to sniff out radioactive sources from up to 15 feet, and then would send in the location to Homeland Security, the FBI and Jack… » 1/24/08 9:25am 1/24/08 9:25am
