Measuring radiation exposure using current FCC guidelines underestimates how much radiation most people receive from their cellphones, researchers said Monday in a study published in the journal Electromagnetic Biology and Medicine. The authors of the study, including several members of Environmental Health Trust, a nonprofit organization devoted to identifying and controlling environmental health risks, pointed to several reasons why. One is that the current assessment method bases evaluations of how much radiation people are exposed to from their phones on measurements taken using a quite large, liquid-filled plastic model of the adult human head (known as the Specific Anthropomorphic Mannequin, or SAM)

What's better than an E Ticket ride? How about an F Ticket? Radiator Springs Racers aims to redefine our expectations of an E Ticket attraction by combining a classic dark ride with a thrilling head-to-head drag race. Currently under construction at Disney California Adventure , the $200-million ride debuting in summer 2012 will take passengers on a four-minute journey through stalactite caverns, around hairpin turns and along high-speed straightaways. Each side-by-side race ends with a randomly selected winner.

There is dancing today in the radiation waiting room. Upright and youthful-looking despite his lined face, the smiling man jitterbugs with any woman who accepts his courteously offered hand. The music he provides by way of a small radio, turned low so as not to disturb those who would rather be quiet as they wait for their treatments. Patients are used to him, enjoying the way he expresses his love of life in his movements to the music of the '50s and '60s — his day. Radiation treatments generally are given five days a week for several weeks, so people get to know one another while they're waiting for their treatment, coming as they do at much the same hour each day. They pass through here by the dozens to the seven treatment rooms, the procedure itself taking mere seconds.

For the first time, astronomers say they've borne witness to a supermassive black hole consuming a star. Two papers released Wednesday by the journal Nature describe powerful blasts of radiation whose brightness and behavior can be explained only by a sun-sized star being torn apart by the gravitational forces of a black hole at the center of its galaxy, the authors say. Scientists believe they have seen the aftermath of such stellar violence...

Still recovering from March's devastating earthquake and tsunami, Japan is stepping up efforts to draw foreign travelers, even recruiting Lady Gaga to spread the word that much of Japan is safe for visitors. As part of the effort to lure visitors before the summer travel season ends, the Japan National Tourism Organization recently posted online the radiation levels for downtown Tokyo, which the tourism group says are lower than in tourist destinations such as New York, Singapore and Hong Kong.

Japanese scientists have some good news for farmers (and eaters) near the crippled Fukushima nuclear power plant: The soil can be made safe for planting. After the meltdown that followed the devastating magnitude 9.0 Tohoku earthquake and resulting tsunami on March 11, radioactive isotopes of cesium escaped from the plant. With a half-life of up to 30 years, those particles threatened to turn Japanese cropland into wasteland for several generations. But as Nature News reported Tuesday, researchers who have been monitoring the soil have found that the Fukushima radiation hasn’t penetrated very far. Most of the fallout is still within the top 2 inches of soil, according to Tomoko Nakanishi, a plant radiophysiologist at the University of Tokyo.

Radiation after a mastectomy for advanced breast cancer is part of the standard treatment guidelines. But more than a decade after the lifesaving value of radiation was confirmed, about half of all women who should get radiation therapy aren't getting it, researchers reported Monday. In the mid-1990s, several studies confirmed that mastectomy patients with advanced breast cancer have better outcomes if they undergo radiation after surgery. Initially, the medical community seemed to pay attention to the findings.

You don't have to be a tinfoil-hat-wearing paranoiac to be worried that the electromagnetic radiation from modern wireless devices may be harmful to your health. But are the "smart meters" being installed by utilities throughout the state frying homeowners' brains, as many consumers and even municipal governments fear? The risks are vanishingly small, while the economic and environmental benefits of smart meters are wide and obvious. In fact, we wish L.A.'s municipal utility would get busy installing the devices, though that isn't likely to happen any time soon.

Koichi Yamada is living proof of an old business axiom: From the jaws of even the worst disaster springs opportunity. Yamada works for one of Japan's top-selling makers of radiation measuring systems. Before the deadly March 11 earthquake and tsunami that ravaged northeast Japan and crippled the Fukushima Daiichi nuclear plant, the company sold 5,000 dosimeters a year. Since the crisis began, orders have exploded to 1,000 a month. "It's been like 'Boom!' with orders, and we couldn't get parts to keep up," said Yamada, department manager at Hitachi-Aloka Medical Ltd. "We've been working overtime and fielding the surge of phone calls.

The parents were furious: Why, they demanded, had Japanese officials raised the acceptable level of radiation exposure for schoolchildren near the crippled Fukushima Daiichi nuclear power plant? By upping the limit, children were allowed on playgrounds containing higher levels of radioactivity than had been permitted before the nearby atomic plant was damaged by the devastating March 11 earthquake and tsunami, the parents said. While it may be impossible to rid the air of dangerous isotopes, they added, the ground is a different matter.
