Details revealed about radioactive contamination spread by MU researcher - Columbia Missourian
The MU lab out of which a researcher inadvertently spread radioactive material last month has been temporarily suspended from using radioactive material, according a report prepared by Peter Ashbrook, director of Environmental Health and Safety at MU.
The lab in Schlundt Annex, headed by Frank Schmidt, professor of biochemistry, will have its radioactive material privileges reviewed in February by MU’s Radiation Safety Committee, according to the report.
MU lab suspended from using radioactive material - Missouri | State & regional - bnd.com
A lab at the University of Missouri-Columbia has been temporarily suspended from using radioactive material after a researcher inadvertently spread radioactive material on the soles of his shoes.
The Columbia Missourian, citing a report from the school's director of Environmental Health and Safety, also reported that a university committee will review the lab's radioactive material privileges in February.
Frank Schmidt, a professor of biochemistry who heads the lab, told the Missourian that he had no comment about the report, which he had not yet seen.
Radiation found outside TMI after incident - The York Daily Record
An Exelon Nuclear monitor located about a mile away from Three Mile Island in Dauphin County picked up trace amounts of radiation during the same week workers were exposed to contamination at the plant.
Between Nov. 18 and Nov. 24, one of TMI's seven remote monitors detected an increase of 0.02 millirems, said Beth Archer, an Exelon spokeswoman. A millirem is a measure of radiation exposure.
A second monitor recorded a statistically insignificant change in its reading, she said.
A typical person receives about 360 millirems of radiation annually from natural sources, such as soil and rocks, cosmic rays, food and consumer products.
Chernobyl Still Radioactive After 23 Years - Even more so than originally expected - Softpedia
Speaking at the annual meeting of the American Geophysical Union (AGU) on Monday, experts revealed a troublesome fact about Chernobyl, the Ukrainian nuclear power plant that blew up in 1986. Recent measurements in the exclusion zone, where no humans can go without protective equipment, have revealed that the radioactive material that was spilled in the area was nowhere near the decay level that was predicted for it. In other words, the scientists are saying that it will take a lot more time for the land to be cleansed than originally believed, Wired reports.
Previous estimates, based on the fact that the Cesium 137's half-life is 30 years, estimated that the restriction zone could be lifted, and then re-inhabited soon. But experiments reveal that the radioactive material is not decaying as fast as predicted, and scientists have no clue as to why this is happening. The April 26, 1986 accident was the largest nuclear accident in the world, and only a level 7 event on the International Nuclear Event Scale. Its fallout was made worse by the Soviet Union's attempt at covering up the incident, which saw a lot of people exposed to lethal doses of radiations.
Live Green at Heart | Knoxville, TN | DOE drills wells to test for the movement of nuclear waste across the Clinch River
The Department of Energy is drilling a series of wells south of the Clinch River to ensure no nuclear waste from Oak Ridge has migrated underground into its neighbors' backyards along Jones Road.
"We have not found any evidence of any contamination south of the river," said David Adler with the Department of Energy. "This is completely a precautionary measure."
North of the Clinch River on DOE property is where nuclear waste was buried from the 1940s until the '80s. The groundwater in this area is known to be contaminated from the hazardous materials. However, recently there were signs that the material may be moving towards the river.
MoD unmoving on atomic veterans - politics.co.uk
The government is refusing to back down over attempts to force it to compensate British nuclear test veterans.
Armed forces minister Kevan Jones admitted he had sympathy for over 1,000 veterans of nuclear tests carried out in the 1950s who are seeking compensation.
But he said their attempts would continue to be rejected by the Ministry of Defence (MoD) because of a lack of "hard evidence" that their illnesses were caused by exposure to radiation.
Labour backbencher Siobhain McDonagh, who obtained the adjournment debate, told the Commons the husband of one of her constituents had committed suicide in 1976 "after 18 years of pain".
The Hindu: 55 workers at Kaiga receive excessive radiation
CHENNAI: About 55 workers of the Kaiga Atomic Power Station in Uttara Kannada, Karnataka, had to undergo medical treatment after they were exposed to an excessive radiation dosage when they drank water that had been mixed with tritium, a highly radioactive substance.
Top officials of the Nuclear Power Corporation of India Limited blamed the incident on “an insider’s mischief.” They alleged that “an insider had mixed tritium in drinking water in a cooler kept in the operating island of the first unit” at Kaiga. The incident took place on November 25, when the first unit (220 MWe) was under shutdown for maintenance.
Asked specifically whether security was so lax at the plant that a worker could access a bottle containing tritium, an authoritative official said there were sampling points in the reactor building from where workers took vials containing radioactive substances to the chemical laboratories for analysis.
“There are standard protocols for handling and managing the transportation and depositing of such radioactive substances. Some insider has played the mischief,” the official said. The incident was detected when the workers’ urine samples showed an excess of tritium.
Associated Press: NRC investigating radiation at Three Mile Island
The U.S. Nuclear Regulatory Commission is sending investigators to the Three Mile Island nuclear power plant after a small amount of radiation was detected there.
About 150 employees were sent home Saturday afternoon after the radiation was detected at the central Pennsylvania plant.
Officials say there is no public health risk.
Exelon Nuclear spokeswoman Beth Archer says investigators are searching for a cause of the release. She says the radiation was quickly contained.
Tests showed the contamination was confined to surfaces inside the building.
AdelaideNow... Maralinga test site returned to people Maralinga Tjarutja people
LAND in outback South Australia used for nuclear weapons testing in the aftermath of World War II will be handed back to the traditional Aboriginal owners.
Environment and Conservation and Aboriginal Affairs and Reconciliation Minister Jay Weatherill today told Parliament the final section of the Maralinga test site would be returned to the Maralinga Tjarutja people.
"The Maralinga nuclear test occurred during a period in our history when little regard was given to Aboriginal people and their connection with the land," he said.
Can radiation treatment hurt others? - The Cornwall Standard Freeholder - Ontario, CA
How careful do patients have to be following nuclear diagnostic tests, or after radiation for the treatment of cancer? How long do these nuclear materials remain in the body? And how long will this radiation remain detectable and transmissible to others?
A report from Johns Hopkins University says that patients, following radiation, must be made aware that they can pass along radiation to others. But unlike cholesterol, this subject is rarely, if ever, discussed at the dinner table. The problem is that nuclear diagnostic tests are not going to go away or decrease. Rather, unless we develop other means of diagnosis, these tests will increase in the years ahead.
During scans to detect thyroid disease, coronary troubles and cancer, radioactive drugs are either injected, taken orally or inhaled. Gamma cameras or positron emission tomography (PET) scanners can then detect this energy and use it to produce images of the body on a computer.
Joplin Independent:Medical scans seen as cause of cancer
“ ... we know that doing 62 million scans every year for a population of 300 million is not just unnecessary and wasteful, but it’s dangerous. It’s producing tens of thousands of cancers.”-- Dr. Atul Gawande, Dana-Farber Cancer Institute, on NPR’s Morning Edition, Sept. 3, 2009
Medical CT and PET scanners expose at least four million North Americans to high doses of radiation each year, a new study shows. Around 400,000 of them get very high doses, higher than the maximum annual doses allowed for nuclear reactor or nuclear weapon site workers, or anyone working with radioactive materials, according to an article in The New England Journal of Medicine (August 27, 2009), “Exposure to Low-Dose Ionizing Radiation from Medical Imaging Procedures.”
EPA's Secret Plan to Raise Public Radiation Exposure Levels Challenged
Public employees have filed a lawsuit demanding documents related to the U.S. EPA's plans made "in secrecy" to allow public exposure to increased levels of radioactivity following nuclear accidents or attacks.
The lawsuit filed Wednesday by Public Employees for Environmental Responsibility under the Freedom of Information Act claims that the agency "wrongfully withheld" comments submitted by EPA and other federal and state agency officials and by representatives of private corporations or trade associations to the EPA Office of Radiation and Indoor Air as it prepared its updated Protective Action Guides.
The radiation guides are protocols for responding to incidents ranging from nuclear power plant accidents to transportation spills to dirty bombs.
NASA to Start Irradiating Monkeys : Discovery News
NASA is stepping up its space radiation studies with a round of experiments that for the first time in decades will use monkeys as subjects.
The point of the experiments is to understand how the harsh radioactive environment of space affects human bodies and behavior and what countermeasures can be developed to make long-duration spaceflight safe for travelers beyond Earth's protective magnetic shield.
For the new study, 18 to 28 squirrel monkeys will be exposed to a low dose of the type of radiation that astronauts traveling to Mars can expect to encounter.
New research suggests how low doses of radiation can cause heart disease and stroke
A mathematical model constructed by researchers at Imperial College London predicts the risk of cardiovascular disease (heart attacks, stroke) associated with low background levels of radiation. The model shows that the risk would vary almost in proportion with dose. Results, published October 23 in the open-access journal PLoS Computational Biology, are consistent with risk levels reported in previous studies involving nuclear workers.
Cardiovascular disease is the leading cause of death and one of the leading causes of disability in developed countries, as reported in the paper and also by the World Health Organization (http://www.who.int/whosis/en/). For some time, scientists have understood how high-dose radiotherapy (RT) causes inflammation in the heart and large arteries and how this results in the increased levels of cardiovascular disease observed in many groups of patients who receive RT. However, in the last few years, studies have shown that there may also be cardiovascular risks associated with the much lower fractionated doses of radiation received by groups such as nuclear workers, but it is not clear what biological mechanisms are responsible.
Study of baby teeth yields new findings on nuclear fallout
Joan Ketterer still recalls the button her son Edward got for donating his baby teeth to what was then a ground-breaking study looking at the effect of nuclear fallout on children born in the St. Louis-area in the 1960s.
"I Gave My Tooth To Science" proclaimed the button, which Edward or "E.J." as his parents called him, proudly wore for days.
But the button was eventually put away. Edward grew up, got married and opened a successful orthodontics practice in Houston. And Joan Ketterer forgot all about the study.
But Tuesday, a New York-based research group released new findings that suggest male tooth donors who ended up with cancer as adults had double the amount of a radioactive isotope created by nuclear fallout than healthy donors who participated in the original St. Louis study.
Radioactive Rabbit Droppings Help Spur Nuclear Cleanup
Putting a new spin on the term "nuclear waste dump," radioactive droppings from Cold War-era critters have spurred a high-tech cleanup funded by the current U.S. government economic stimulus program.
Government contractors this September flew a helicopter equipped with radiation detectors and GPS equipment over scrubland in eastern Washington State near the vast Hanford Site, a 1950s plutonium-production complex.
The goal was to pinpoint soils contaminated with harmful radioactive materials that had been spread far a field within the complex by animals and the wind.
French Senate passes nuclear compensation bill
The French Polynesian Nuclear Test Veterans Association says it’ll fight for a better package for the victims of the French nuclear test fallout.
The French Senate has passed a bill to compensate nuclear test veterans for the consequences of its weapons tests between 1960 and 1996 in French Polynesia and Algeria.
France had earlier said its test were safe and clean.
Moruroa e Tatou’s head, Roland Oldham, says the Loi Morin is unjust.
Apology sought for abuse at Fernald School - Waltham, MA - Wicked Local Waltham
In the dark past of the Fernald School for the disabled, the nation's oldest publicly funded facility for those with developmental disabilities, some children were subject to Cold War experiments including being fed radioactive cereal while other patients allegedly were tagged as "morons" even as tests showed them to be normal.
Now two Massachusetts lawmakers want the state to do right by the former residents of the controversial Fernald School, which opened in 1848 and is slated to closed next year.
State Rep. Thomas Sannicandro, D-Ashland, has filed a bill that would require the state to apologize for alleged civil rights violations among patients at the Waltham facility. And state Rep. Thomas Stanley, D-Waltham, has filed a bill calling for a formal investigation of the misclassification of patients there.
Both bills will be heard during a hearing Tuesday before the Joint Committee on Children, Families and Persons with Disabilities.
Hanford News : LA hospital: Error caused 206 radiation overdoses
LOS ANGELES (AP) - Hospital officials say a computer-resetting error caused radiation overdoses for 206 patients who underwent CT scans at Cedars-Sinai Medical Center.
In a written statement Monday, hospital officials said "a misunderstanding about an embedded default setting applied by the machine" resulted in a higher than expected amount of radiation.
Officials say the 206 patients received eight times the normal dose of radiation - an error that went undetected for 18 months. A hospital spokesman says about 40 percent of the patients lost patches of hair as a result.
The scanners' manufacturer, General Electric, says the machine was not defective.
As a result of the discovery, the FDA issued an alert Thursday urging hospitals nationwide to review their safety protocols for CT scans.
The Acreage cancer: NYC law firm affiliated with Erin Brockovich finds high radiation in some Acreage water -- South Florida Sun
Radiation levels were higher than normal at the homes of as many as 10 Acreage families with brain tumors or brain cancer, according to a New York City law firm affiliated with the nationally known environmental activist Erin Brockovich.
The radiation appears to be coming from well water, said Lemuel Srolovic, an attorney with the law firm Weitz & Luxenberg, which is investigating a suspected cancer cluster in the semi-rural community. A Stuart engineering company hired by the firm measured the radiation in mid-September using a Geiger counter.
"Generally, it showed there appeared to be radioactive material in ground water being drawn up," Srolovic said.
A report issued last week by the state Department of Environmental Protection similarly found elevated levels of radioactive particles in four wells in The Acreage. But the DEP stressed that the radiation can occur naturally, and the report said the problem is "simple" for homeowners to address by installing water-treatment systems.
