2 exposed to plutonium at SRS 122309 - The Augusta Chronicle
Two Savannah River Site workers were discovered with traces of plutonium 238 on their clothing in November, but followup monitoring concluded they received no internal exposure.

“In this case, the two people had contamination on their clothing, but not on themselves,” said Will Callicott, spokesman for Savannah River Nuclear Solutions, the site’s primary contractor. “The contamination was detected through routine monitoring while exiting the work area, so the radiation detection system worked as designed.”
The incident occurred the week of Nov. 13 in the site’s Solid Waste Management Facility, according to a report made public this month by the Defense Nuclear Facilities Safety Board.
Risk unlikely to be great unless exposure was very high - Times Online
Tritium is a radioactive isotope of hydrogen, which has one proton and two neutrons, where a normal atom of the element would have one proton and no neutrons. It is produced naturally when hydrogen is bombarded by cosmic rays, and is also a by-product of reactions that drive nuclear power plants.
Tritium atoms almost invariably bind to oxygen atoms, to create tritiated water. The isotope is a weak source of radiation, emitting low-energy beta particles that cannot penetrate the skin, and are therefore not dangerous outside the body.
If inhaled or swallowed, however, the beta particles present a radiation hazard.
As with all poisons, the risk depends on the dose.Trace levels of tritium are present naturally in all water supplies and are not harmful. Higher exposures, however, may cause cancer, and have also been linked to birth defects in the children of people who are exposed.
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.
BBC NEWS | UK | Sellafield admits exposure case
Sellafield has pleaded guilty to health and safety breaches after two contractors were exposed to radiation.
The workers were refurbishing a floor at the site's plutonium finishing and storage plant in July 2007 when they were exposed to airborne contamination.
Sellafield Ltd admitted failing to discharge its duty under the Health and Safety Act 1974 at Whitehaven Magistrates' Court on Friday.
Veteran exposed to nuclear radiation for tests | News-Leader.com | Springfield News-Leader
On the Fourth of July weekend of 1957, Darrell Robertson was on a train from Fort Lewis, Wash., to southern Nevada. He was one of hundreds of young men with orders in hand to take part in a training exercise that they were told was crucial to the fight against communism.

The native of Lamar was headed deep into the burnt landscape of the Mojave Desert, to a place called Camp Desert Rock. There, between 1945 and 1958, the U.S. military conducted 106 atmospheric nuclear tests.
At the time, Robertson said, military brass believed a nuclear confrontation with the Soviets was likely. They were intent on developing a group of troops hardened by repeated exposure to radiation. They thought exposure to radiation was like sunning on the beach: First you burn, then you tan.
BBC NEWS | UK | England | Cumbria | Staff contaminated at Sellafield
The operators of Sellafield are to be prosecuted after two contractors received a "higher than anticipated" dose of radiation.
The workers were refurbishing a floor at the site's plutonium finishing and storage plant in July 2007 when they were exposed to airborne contamination.
Sellafield Ltd is accused of failing to discharge its duty under Section 3 (1) of the Health and Safety Act 1974.
The case will be heard at Whitehaven Magistrates' Court on 24 July.
Hanford panel seeks more beryllium exposure tests
Too few workers at the Hanford nuclear reservation are being tested for exposure to beryllium, a metal that can cause fatal lung diseases, according to an Energy Department advisory panel.
Based on the number of affected workers, beryllium is a greater safety risk at the Eastern Washington complex than radiation, according to Hanford Advisory Board recommendations issued during meetings Thursday and Friday in Portland, Ore.
To date, 4,538 Hanford employees have had blood tests for beryllium sensitivity or disease, and 27 have been diagnosed with chronic beryllium disease, an incurable lung ailment that afflicts workers who develop an allergy-like sensitivity to the light, gray-colored metal. Six of those cases have been diagnosed since 2007.
Tonko: Study NL site impac -- Times Union - Albany NY
A congressional subcommittee on Thursday rapped a federal regulatory agency for downplaying the risks of uranium exposure to former workers and neighbors of the long-shuttered National Lead Industries munitions plant in Colonie.
Democratic lawmakers said the handling of toxic exposures at the defunct plant and other sites nationwide showed that the 29-year-old U.S. Agency for Toxic Substances and Disease Registry isn't doing enough to investigate legitimate health concerns.
"It's clear ... that the ATSDR failed the people of Colonie and Albany who live near the site," said U.S. Rep. Paul Tonko, D-Amsterdam.
Radiation Exposure Compensation Program - About the Program
On October 5, 1990, Congress passed the Radiation Exposure Compensation Act ("RECA" or "the Act"), 42 U.S.C. § 2210 note, providing for compassionate payments to individuals who contracted certain cancers and other serious diseases as a result of their exposure to radiation released during above-ground nuclear weapons tests or as a result of their exposure to radiation during employment in underground uranium mines. The 1990 Act provided fixed payments in the following amounts: $50,000 to individuals residing or working "downwind" of The Nevada Test Site; $75,000 for workers participating in above-ground nuclear weapons tests; and $100,000 for uranium miners.
2 more exposed to low radiation dose after nuclear fuel plant spill - Mainichi Daily News
Two more workers have been exposed to a small amount of radiation after an accident at a nuclear fuel processing plant here, bringing the number of victims to four, the plant operator said Saturday.
None of them suffered any illness as a result, and the radiation did not contaminate the environment around the facility in Yokosuka owned by Global Nuclear Fuel-Japan Co., according to the company.
Britain admits dangers of 1950s nuclear tests - World - smh.com.au
British defence chiefs have admitted servicemen were exposed to dangerous radiation during nuclear tests in Australia and the South Pacific in the 1950s.
The admission, made after years of denials, is in papers filed with the High Court in London by Ministry of Defence lawyers.
Repeat Beryllium Violations Alleged
A Marion, Ohio, company that bills itself as the "World's Largest Manufacturer of Beryllium Copper Plunger Tips" has been charged by U.S. OSHA with repeat violations of standards to protect workers from overexposure to beryllium.
OSHA says it opened its inspection in October 2007 to determine if the company had corrected safety hazards found during a 2005 inspection. According to OSHA, the company had not righted the problems.
I Was An Atomic Test Guinea Pig (from Oxford Mail)
A pensioner who says he was a "guinea pig" during atomic bomb tests in the 1950s is suing the Government.
Ex-serviceman Derek Connelly, of Churchill Road, Kidlington, says he was made to stand just wearing his shorts and socks to witness nuclear and hydrogen bombs being set off in the Pacific Ocean 50 years ago.
Government ordered British troops to crawl through radioactive fallout - Sunday Mirror
Government scientists ordered British troops to crawl through radioactive fallout in a deadly series of experiments.
They had to scramble on their hands and knees through the dust left by four nuclear bombs to "ensure as much contamination as possible gets on to their clothes".
