WASHINGTON, Sept. 20, 2011 /PRNewswire-USNewswire/ -- Two organic farmers from Japan, their children and fellow Japanese anti-nuclear campaigners made a plea for the safety of Fukushima's children at a press conference in Washington, D.C. today. "Our hearts have been torn apart in the Fukushima community because of the nuclear disaster," said Sachiko Sato, a natural farmer from Fukushima Prefecture, who evacuated four of her six children two days after the March 11, 2011 Fukushima nuclear...
Beginning Sunday, September 18, 2011 at NASA's launch facility in Fort Sumner, New Mexico, space scientists from the University of New Hampshire will attempt to send a balloon up to 130,000 feet with a one-ton instrument payload to measure gamma rays from the Crab Pulsar, the remains of a supernova explosion that lies 6,500 light years from Earth. The launch is highly dependent on weather and wind conditions, and the launch window closes at the end of next week. The Gamma Ray...
In the news release, STMicroelectronics Further Extends its Range of Rad-Hard Analog Products for Aerospace, issued 15-Sep-2011 by STMicroelectronics over PR Newswire, we are advised by the company that the fourth paragraph, the text should be updated to reflect that "extension of the product family includes the following four devices" rather than as originally issued inadvertently. The complete, corrected release follows: STMicroelectronics Further Extends its Range of Rad-Hard Analog...
GENEVA, Sept. 15, 2011 /PRNewswire/ -- STMicroelectronics (NYSE: STM), a global semiconductor leader, serving customers across the spectrum of electronics applications and a world leader in ICs for the aerospace market, today announced the expansion of its European Rad-Hard aerospace portfolio with the addition of four amplifiers which, have achieved official QML V qualification. The qualification of these devices further extend the solid foundations of ST's analog radiation-hardened...
Terahertz (THz) technologies show promise for myriad medical, military, security, and research applications ranging from the detection of cancer to airport security systems to shipment inspection to spectroscopy. Relatively little is known, however, about the effect of THz radiation on biological systems. So a team of researchers, led by Los Alamos National Laboratory, evaluated the cellular response of mouse stem cells exposed to THz radiation. They applied low-power radiation both from a...
The amount of radiation released during the Fukushima nuclear disaster was so great that the level of atmospheric radioactive aerosols in Washington state was 10,000 to 100,000 times greater than normal levels in the week following the March 11 earthquake and tsunami that triggered the disaster. Despite the increase, the levels were still well below the amount considered harmful to humans and they posed no health risks to residents at the time, according to researchers at The University of...
WASHINGTON, Sept. 9, 2011 /PRNewswire-USNewswire/ -- NASA is funding nine proposals from eight states to investigate space radiation's effect on human explorers. The proposals from researchers in California, Colorado, Florida, Georgia, Maryland, Massachusetts, New York and Texas have a total value of approximately $12 million. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The ground-based studies will work to better understand and mitigate risk of damage to the...
Better physics teaching with a particular emphasis on radioactivity and radiation science could improve public awareness through education of the environmental benefits and relative safety of nuclear power generation, according to leading Brazilian scientist Heldio Villar. He suggests that it might then be possible to have a less emotional debate about the future of the industry that will ultimately reduce our reliance on fossil fuels. To environmental activists, nuclear power and...
Two remarkable pulsed-power machines used to test the nation's defenses against atomic weapons have surpassed milestones at Sandia National Laboratories: 4,000 firings, called 'shots,' on the Saturn accelerator and 9,000 shots on the HERMES III accelerator. Saturn — originally projected to last 5 to 10 years — began operating in 1987. Its major function has been to produce X-rays to test the effectiveness of countermeasures used to protect electronics and other materials against X-ray...
Trio of Experts Outline Eight Key Concerns: Ongoing Health Woes in Japan, Unaddressed Design Flaws and Inadequate U.S. Regulatory Response Seen As Troubling. WASHINGTON, Sept. 8, 2011 /PRNewswire-USNewswire/ -- Regulatory, scientific and health experts agree: The "3/11" Fukushima reactor disaster is still ongoing six month later ... and some major lessons are in danger of going unheeded. Sunday marks the six-month anniversary of the Fukushima nuclear reactor crisis. In anticipation of...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...
The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
