...absence of calcified or non-calcified plaque," says Dr. Norman Lepor, a professor at UCLA's Geffen School of Medicine, referring to the tell-tale build-up on artery walls that signifies heart disease. Lepor says that CTCA gives off no more radiation than the routinely used diagnostic nuclear stress test, which also detects plaque deposits, but only those that are big enough to block 70% of the artery. "The risk-benefit assessment is in favor of cardiac CT to be used in a judicious fashion," says Lepor, who describes good candidates for the scan as male, over...
...magnitude 6.8 earthquake that hit the northwest coast of Japan Monday morning is rocking the country's faith in its nuclear power plants, raising questions about the safety of facilities that provide a third of the energy consumed by the quake-prone archipelago...
...reportedly still missing. That's far less than a 2004 quake that struck the same area and killed more than 60 while leaving 16,000 homeless. But instead of feeling relief, the entire country has been rattled by TV images of black smoke billowing from Niigata's Kashiwazaki Kariwa nuclear power plant, located just 9km (5.6 miles) from the epicenter in the Sea of Japan. The plant suffered a string of problems when the temblor struck. Tokyo Electric, the Kashiwazaki plant's owner/operator, was quick to point out that a smoky fire that broke out in an electric transformer posed...
...amount of radioactivity escaping into the environment from the water and exhaust leaks was reportedly minuscule and posed no threat to people or the surrounding area. But questions are being raised over the safety of 16 other nuclear plants located throughout Japan, a nation that lies atop numerous active fault lines. The intensity of Monday's quake was 2.5 times the level the power plant's structures were built to sustain without any damage...
...Just because the quake was double the quake-resistant standard, it doesn't automatically mean a threat," says Shuji Kawahara, an earthquake safety inspection official in the Ministry of Economy, Trade and Industry's nuclear safety department. "The structures are built to withstand much much more," he said. How much more? "We don't know," says Kawahara...
