Future moon explorers will be bombarded with two to three times more radiation than astronauts aboard the International Space Station, a health hazard that will require thick-walled shelters for protection, scientists reported Friday.
The “Fat Man” bomb fueled by Hanford plutonium that leveled Nagasaki and ended World War II was only the opening salvo in Hanford’s lengthy and controversial nuclear mission.
A Japanese court on Wednesday for the first time recognized people exposed to radioactive “black rain" that fell after the 1945 U.S. atomic attack on Hiroshima as atomic bomb survivors, ordering the city and the prefecture to provide the same government medical benefits as given to other survivors.
A Spokane-based study found that a healthy body’s biological clock plays a role in protecting the heart against the toxicity of radiation treatment in mice.
A new report warns that a huge facility on the Hanford Nuclear Reservation in Washington state is at risk of releasing radioactive contamination into the environment the longer it remains standing.
The Environmental Protection Agency has appointed a scientist who argues for easing regulations on lower-level radiation exposures to lead the agency’s radiation advisory committee.
Air monitoring systems were set up Tuesday to check for low-level nuclear radiation and other harmful contaminants following a powerful weekend blast at a hazardous waste site in Idaho that killed a worker, destroyed a building and damaged other structures, an official said.
A study by Chinese geologists shows the mountain above North Korea’s main nuclear test site has collapsed under the stress of the explosions, rendering it unsafe for further testing and necessitating monitoring for any leaking radiation.
New test results show that monitoring for airborne radioactive contamination has not protected some Hanford Nuclear Reservation workers demolishing the Plutonium Finishing Plant.
Demolition at a highly contaminated complex at the Hanford nuclear reservation has been halted.
U.S. officials want to fine an Idaho company that sent radioactive materials across the country that leaked from lead containers and exposed FedEx workers. The Nuclear Regulatory Commission on Thursday announced a proposed $22,400 fine for Idaho Falls-based Qal-Tek Associates...
The announcement this month that 31 Hanford workers were contaminated from a June 8 incident is raising more questions about how government agencies alert the public about the test results of leaks from one of the world’s most polluted sites.
A federal court ruling says the Department of Energy had no obligation to continue full pension benefits for Hanford nuclear reservation workers who were required to switch from one employer to another in a 1996 contracting change.
State health officials say radioactive plutonium and americium have been found in air samples collected where workers enter the secure area of the Hanford nuclear reservation in southeastern Washington.
The Department of Energy would be required to establish a resource center to help Hanford workers exposed to chemical vapors, under proposed federal legislation.
An underwater robot captured images of lava-like lumps Thursday inside a damaged reactor at Japan’s crippled Fukushima nuclear plant, spotting for the first time what is believed to be nuclear fuel that melted six years ago.
An underwater robot entered a badly damaged reactor at Japan’s crippled Fukushima nuclear plant Wednesday, capturing images of the harsh impact of its meltdown, including key structures that were torn and knocked out of place.
The Nuclear Regulatory Commission has issued a “white” violation finding against the nuclear power plant near Richland related to a November radioactive waste shipping incident.
Federal officials say testing of a small-scale version of a key component of an eastern Idaho radioactive waste treatment facility that has so far failed to operate is making progress at finding a solution.
An acting leader for the Department of Energy’s nationwide nuclear environmental cleanup program, including the Hanford nuclear reservation, was named on Tuesday.
