Radiation Exposure and Risk

Ionizing radiation damages living things and contaminates the environment, sometimes permanently. Studies have shown increases in cancer around nuclear facilities and uranium mines. Radiation mutates genes which can cause genetic damage across generations.

Landfill fire near radioactive waste dump raises alarm in St. Louis

Kay Drey, Beyond Nuclear board member and long-time watchdog on West Lake landfillIn early May, Rolling Stone quoted Beyond Nuclear board member Kay Drey (photo, left), regarding a municipal garbarge dump fire burning underground precariously near a radioactive waste dump near St. Louis.

Kay is a long-time watchdog on the West Lake landfill, a radioactive waste dump in the Missouri River floodplain near St. Louis.Mallinckrodt Chemical Co. processed Belgian Congo uranium during the secret Manhattan Project race to develop the atomic bomb in the 1940s. Those radioactive wastes were then dumped at the West Lake landfill in 1973. EPA wants to abandon them in place. Kay has long worked to have them removed from the Missouri River floodplain, not far upstream from St. Louis drinking water supply intakes.

Now the Associated Press/New York Times and St. Louis Magazine have reported on "the possibility of a slow-moving disaster right before our eyes," in the words of Ed Smith of the Missouri Coalition for the Environment. The former article focuses on the health risks to nearby communities if the fire reaches the radioactive waste dump, while the latter article focuses on the health damage that the radioactive wastes may have already inflicted, especially in local children downstream.

Risk of "dirty shutdown" at Paducah gaseous diffusion uranium enrichment plant

Photo credit: USEC/U.S. Department of EnergyIn a two-part series, Geoffrey Sea of Neighbors for an Ohio Valley Alternative (NOVA) has exposed deep financial troubles which could lead to major radiological risks at the Paducah gaseous diffusion uranium enrichment plant in Kentucky. Mind boggling mismanagement, or worse, by U.S. Enrichment Corporation (USEC) and the U.S. Department of Energy (DOE) are to blame.

Part I, entitled "Countdown to Nuclear Ruin at Paducah," was published May 22nd, and warned that there were just 9 days left to avert a "dirty shutdown" in the many miles of enrichment cells. If the uranium laden gas solidifies within the system, it will make eventual decommissioning and clean up astronomically expensive for taxpayers, and radiologically risky for workers.

Part II, "Slow Cooker at Paducah Comes to a Boil,"  was published May 28th, with only three days left to avert dirty shutdown.

Paducah has operated since the 1950s. Sea reports that Paducah, which employs the highly energy intensive gaseous diffusion uranium enrichment process, has the single biggest electric meter in the country, electrified by two dirty coal plants. It is also one of the single biggest emitters of ozone layer destroying CFC-114, which also happens to be a very potent greenhouse gas.

In September 1999, Joby Warrick of the Washington Post broke the story that post-reprocessing uranium from Hanford Nuclear Reservation, containing fission products and transuranics, had been secretively run through Paducah. Local residents, such as Ron Lamb, had already been long protesting Technetium-99 in his drinking well water, however. Paducah whistleblower Al Puckett helped expose a secret dumping ground for radioactive and hazardous wastes on site. Such revelations help to explain the high cancer rate amongst Paducah workers and area residents.

As Sea reports, USEC is still seeking a $2 billion federal loan guarantee from the Obama administration for its proposed American Centrifuge Plant at Portsmouth, Ohio. Newly confirmed Energy Secretary Ernest Moniz has deep ties to USEC, both during his time in the Clinton DOE, as well as afterwards, as a paid private consultant.

Entergy's Palisades leaks 79 gallons of radioactive water into Lake Michigan, forced to shut down

Entergy's Palisades atomic reactor on the Lake Michigan shore in southwest MIAs reported by the Holland Sentinel, Entergy's Palisades atomic reactor has yet again sprung a leak, this time spilling 79 gallons of supposedly "very slightly radioactive water" into Lake Michigan, the headwaters of 20% of the world's surface fresh water, and drinking water for 40 million people downstream. 

Entergy and NRC spokespersons' repeated claims of no safety significance to the public flies in the face of decades of findings, as by the National Academy of Science (most recently in 2005), that any exposure to radioactivity, no matter how small, carries a health risk of cancer, and that these health risks accumulate over a lifetime.

U.S. Representative Ed Markey (D-MA) made public the serious nature of this particular leaking tank in June 2012. His information came from very courageous Palisades whistleblowers, and their attorney, Billie Pirner Garde. The leak, from the 300,000 gallon Safety Injection Refueling Water (SIRW) storage tank located directly above the control, began in mid-2011, and was flowing through the ceiling, and being captured in buckets in the safety critical control room, full of electrical circuitry and equipment that cannot get wet. The leak was concealed not only from the public and media, but even from the NRC's own Chairman, Greg Jaczko, as he toured Palisades on May 25, 2012. NRC later granted Entergy an exemption in 2012 to allow continued operations despite the degraded condition of the SIRW storage tank. 

In recent weeks, Beyond Nuclear learned from NRC officials that the now two-year-old leak has continued at a 0.5 to 1 gallon per day rate. But Saturday's leakage rate, which forced the reactor to shut down, was at 90 gallons per day, as documented in NRC's event notification report. Palisades' SIRW storage tank, just like the rest of the plant, is 46 years old, and obviously showing severe signs of "breakdown phase" age-degration, of increasing risk. 

The Detroit Free PressEnformable Nuclear NewsKalamazoo GazetteMichigan RadioWSJM RadioWKZO Radio,WWMT TV-3 KalamazooDetroit News,  and WOOD TV-8 Grand Rapids have reported on this story.

Beyond Nuclear issued a media statement, challenging flippant Entergy and NRC claims that this leak carries "absolutely" no risk to human health and safety. NRC's Region 3 spokeswoman has been exposed making false claims regarding radioactivity leaks more than once at Midwestern reactors in just the past year, prompting the demand for an investigation by a member of Congress. Last year, U.S. Rep. Dennis Kucinich (D-OH) demanded an NRC investigation into Mytling's downplaying of a reactor leak at the troubled Davis-Besse atomic reactor near Toledo. In addition, Chicago watchdog group Nuclear Energy Information Service, via a Freedom of Information Act Request to the State of Illinois Dept. of Nuclear Safety, documented that Mytling's flip assurance -- that a radioactive steam leak at the Byron atomic reactor, in Jan. 2012, must have contained exceedingly low levels of hazardous radioactive tritium, as radiation monitors had not detected any -- was baseless and misleading, as no real-time tritium monitoring capability existed at the plant. Similar questions must now be asked of Mytling's questionable assurances that radioactivity levels in the water leaked into Lake Michigan were below detectable levels. Are there radiation monitors in place to verify such flip assurances?
