Greenpeace said Friday that it has detected dangerous levels of radioactivity near a salvage yard in New Delhi where a worker was killed last month from radiation poisonings. Seven others were hospitalized. The group said experts sensed radiation 5,000 times above normal levels at the privately owned facility in the city's overcrowded Mayapuri district and nearby areas."We picked up six hotspots between 65 and 165 feet from the scrap yard, which means radiation has spread into the streets,...
CHARLOTTE, N.C., May 5 /PRNewswire/ -- Hendrick Construction, Inc. finished a 14,000-square-foot expansion project at Oak Ridge National Laboratory, upgrading lab space at one of the world's premier research facilities. The Tennessee project created 13 new labs to support scientific research conducted at the Spallation Neutron Source (SNS), the world's most powerful pulsed source of neutrons for the study of materials. Scientific understanding of the molecular structure of materials is...
A giant laser -- the size of three football fields -- is being used by scientists at a government lab in California to possibly set off a nuclear reaction so intense that it will make a star bloom on the surface of the Earth, according to a recent CNN report. The scientists at the Lawrence Livermore National Laboratory want to create a sun on the ground that seems like a science fiction fantasy straight from Hollywood. But the experiment is for real, and the National Ignition Facility will be...
Study refines predictions of what may constitute evidence of elusive particlesAstrophysicists are looking everywhere "“ inside the Large Hadron Collider, in deep mines and far out into space "“ for evidence of dark matter, which makes up about 25 percent of the energy density of the universe.Despite the recent tantalizing observation of excess high-energy positrons "“ thought to be due to dark matter "“ UC Irvine researchers say we're not quite there yet.Models predict that when...
A researcher at North Carolina State University has helped to develop a new method for describing the binding of protons and neutrons within nuclei. This method may improve scientists' ability to predict and understand astrophysical reactions within stars.When protons and neutrons bind, the process releases energy. This fusion energy is how stars burn. If scientists can determine where these particles are, what they are doing, and how they are binding, they will then be able to more...
Observations of how the youngest-known neutron star has cooled over the past decade are giving astronomers new insights into the interior of these super-dense dead stars. Dr Wynn Ho will present the findings on Thursday April 15th at the RAS National Astronomy Meeting in Glasgow.Dr Ho, of the University of Southampton, and Dr Craig Heinke, of the University of Alberta in Canada, measured the temperature of the neutron star in the Cassiopeia A supernova remnant using data obtained by NASA's...
Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have pushed the limits of charge breeding and broken a long-standing world record for ionization efficiency of solids.Argonne's Californium Rare Isotope Breeder Upgrade (CARIBU) project has reached 11.9 percent efficiency with metallic particles of rubidium. The previous metal record was 6.5 percent, using potassium, achieved at Laboratory of Subatomic Physics and Cosmology (LPSC) in Grenoble."There have been...
Element 117 fills in the final gap in the list of observed elements up to element 118A collaboration of Russian and US physicists has finally created element 117 - a superheavy element made of atoms containing 117 protons that is roughly 40% heavier than lead. The achievement fills in the final gap on the list of observed elements up to element 118. The team produced the elusive element 117 by fusing together atoms of calcium and another rare, heavy element known as berkelium. The research...
ST. LOUIS, April 7 /PRNewswire-FirstCall/ -- Sigma-Aldrich® (Nasdaq: SIAL) announced today that it has signed an agreement with New Mexico Highlands University through its licensee, Highlands Stable Isotope Corp. (HSI), to exclusively distribute a novel set of patented stable isotope labeled synthetic reagents (www.sigma-aldrich.com/sinext). Under the terms of the agreement, HSI, a leader in the synthesis of amino acids, natural products, monomers for the materials science industry and...
An experiment led by a University of Alberta researcher, at the Large Hadron Collider (LHC) at CERN, could dramatically change our concepts of basic physics, revolutionize our understanding of the Universe and could eventually lead to technologies in future generations that right now only exist in science fiction.U of A physics professor James Pinfold is leading an international team of physicists who will use ultra high energy proton collisions. The protons will move at very near the speed...

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...
Fermium is a synthetic, radioactive metallic element. It has the symbol Fm and atomic number 100. It is an element in the actinide series. It is named after nuclear physicist Enrico Fermi. Fermium became the eighth transuranic (having an atomic number greater than 92) element discovered. It was first discovered in 1952 by a team of scientists led by Albert Ghiorso. They found fermium-255 in debris of the first hydrogen bomb explosion from Operation Ivy. Fermium-255 was created when...
Americium is a synthetic radioactive metallic element. The symbol for Americium is Am and the atomic number is 95. Americium is an actinide that was first isolated by Glenn T. Seaborg in 1944 while attacking plutonium with neutrons. It became the fourth transuranic (having an atomic number greater than 92) element to be discovered. It was named for the Americas. It is widely used in commercial smoke-detectors and different types of industrial gauges. Americium in its pure state has a...
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...
