Low radiation doses might not be proportional to risk

Low radiation doses might not be proportional to risk

Through a combination of time-lapse live imaging and mathematical modeling of a special line of human breast cells, researchers have found evidence to suggest that for low dose levels of ionizing radiation, cancer risks may not be directly proportional to dose. This contradicts the standard model for predicting biological damage from ionizing radiation

Towns near NM fire, nuclear lab wary of smoke

Towns near NM fire, nuclear lab wary of smoke

Los Alamos, both the town and the laboratory of the same name, remains evacuated as a major wildfire spreads has reached the roadway just outside some of the laboratory’s property. Top lab officials and fire managers said they're confident the flames won't reach key buildings or areas where radioactive waste is stored, but some residents remained concerned for the safety of their families and nearby communities.

U.S. nuke regulators weaken safety rules

U.S. nuke regulators weaken safety rules

According to an extensive investigation by the Associated Press, federal regulators have been working closely with the nuclear power industry to keep the nation's aging reactors operating within safety standards by repeatedly weakening those standards. The report claims that nuclear regulatory officials have often decided original regulations are too strict and has argued that safety margins could be eased without peril.

The energy debate: coal vs. nuclear

The energy debate: coal vs. nuclear

Two Rutgers energy and environment researchers recently completed work on a long-term study of consumers’ attitudes toward two high-profile energy sources: coal and nuclear energy. Their work finds that while global warming and safety do factor into Americans’ decisions on these two forms of energy, other factors are at play that figure into their choices.

Expert discovers simple method to immobilize radioactive iodine

Radioactive iodine-129 has an extremely long half life of 15.7 million years, and is one of the most significant long term nuclear waste hazards. A researcher in England has found an easy way to lock up the slowly decaying iodine by using a material that absorbs a microwave frequency that iodine-129 does not.

How much radioactivity is in the oceans?

How much radioactivity is in the oceans?

Some scientists have debated the actual severity of the nuclear power plant incident at Fukushima Dai-ichi, but its impact on the ocean is no question much greater than that of Chernobyl. Now, researchers at Woods Hole Oceanographic Institution are starting to build a global database of baseline levels of marine radionuclides so they can be more accurately tracked in the future.

Asia nuclear reactors face tsunami risk

Asia nuclear reactors face tsunami risk

The world's most seismically charged region is undergoing a nuclear renaissance as it struggles to harness enough power for its huge populations and booming economies. But China, Taiwan, India and several other countries have made little use of new science to determine whether these areas are safe. At least 32 plants in operation or under construction in Asia are at risk of one day being hit by a tsunami, nuclear experts and geologists warn.

U.S. spent-fuel storage sites are packed

U.S. spent-fuel storage sites are packed

The nuclear crisis in Japan has laid bare an ever-growing problem for the United States — the enormous amounts of still-hot radioactive waste accumulating at commercial nuclear reactors in more than 30 states. A state-by-state study of numbers obtained by the Associated Press finds that the U.S. has almost 71,862 tons of radioactive waste, now stored at power-plant sites.

R&D 100 Award-winning technology helps find radiation from Japan

R&D 100 Award-winning technology helps find radiation from Japan

Last week, Pacific Northwest National Lab was the first to detect radioactive isotopes entering the continental United States. Though levels of the detected materials, xenon-133, were extremely low—less than one-millionth the daily dose of background radiation—the technology proved the sensitivity of two instruments originally developed to help enforce nuclear weapon testing bans. One of them won an R&D 100 Award in 1998.

Risks from radiation low in Japan but panic high

Risks from radiation low in Japan but panic high

Those who have been evacuated from the site are considered safe, as are the 39 million people who live in the greater Tokyo region. But panic continues, as supermarkets in nearby China have run out of staples such as salt, and Russians have rushed to buy seaweed and red wine, a measure Soviet authorities recommended after the Chernobyl explosion.

JEOL to launch world's smallest solid-state NMR probe
JEOL to launch world's smallest solid-state NMR probe

According to JEOL Resonance, a new benchmark for resolution and benchmark will be set with its introduction next week of a new 0.75-mm solid state nuclear magnetic resonance (NMR) probe. The probe is capable of high resolution sample analysis by spinning the sample at 110 kHz, the world's fastest spinning speed for NMR.

Energy Harvesting Subsystems for Wireless Sensors

Nextreme Thermal Solutions has developed two new energy harvesting subsystems for the plumbing and HVAC industries. The subsystems are the latest additions to Nextreme's Thermobility energy harvesting platform that uses thin-film thermoelectric technology to convert available thermal energy into electric power for a variety of autonomous self-powered applications.
