Spike in radiation levels after toxic waste leak at Washington nuclear site
The recent readings from the Environmental Protection Agency (EPA) obtained by RT have revealed that a sharp spike in the radiation level had been registered in Richland on the morning of May 5.
The readings show the random jump when the toxic fume rates briefly reached around 410 CPM [counts per minute], nearly the highest possible level. It equals to around 4 microsieverts (uSv) per hour, a common measurement of radioactivity. To put this into perspective, the single lifetime human dose should be between 0.71 uSv/hour and a maximum of 5.7 uSv/hour, according to Radiation Survival.
Speaking of public health, levels between 2 uSv/hour and 5 uSv/hour are considered “elevated risk” which requires taking “safety precautions” and relocating “as soon as possible.”
Long-term exposure to radiation is required to really cause serious harm, as it happened in the infamous cases of Chernobyl or Fukushima.
As of Friday afternoon, there have been no media reports suggesting that an evacuation or other measures and guidance have been ordered for Richland.
RT's Alexey Yaroshevsky has spoken to area residents, who told him that the Hanford Nuclear Reservation “burps radiation" and that this registered spike might have been one of them.
It is unclear though, how often these “burps” strike, or for how long they have been happening already.
The most recent radiation spike comes less than a month after a massive leak was first detected at the nuclear facility’s AY-102 double-shell tank, on April 17.
The Washington state Department of Ecology said then that there was “no indication of waste leaking into the environment or risk to the public at this time.” It added that the leak was an “anticipated” outcome of an ongoing effort to empty the tank.
In general, the department considers Hanford “safe”, saying that the waste there is contained.
“It isn’t accessible to the public, and employees who perform cleanup work receive specialized training and wear protective gear,” the DoE said.
The tank originally held some 800,000 gallons of waste, and has been known to experience minor leakage since 2011. At the time, this fact did not merit much attention from the local authorities. The government contractor managing the tanks, Washington River Protection Solutions, did not acknowledge the problem until 2012.
“It makes me sad that they didn’t believe me that there was a problem in 2011,” Mike Geffre, who detected the leak in 2011, told KING-TV. “I wish they would have listened to me and reacted faster. Maybe none of this would be happening now. It’s an example of a culture at Hanford of ‘We don’t have problems here. We’re doing just fine.’ Which is a total lie.”
Hanford is located on the Columbia River in eastern Washington, near the border with Oregon. Built during World War Two as part of the Manhattan Project to develop the nuclear bomb, it still contains roughly 53 million gallons – over 2,600 rail cars – worth of high-level nuclear waste, left from the production of plutonium for the US nuclear weapons program.
Since 1989, the only work at the Hanford Site has been related to cleaning up the waste left behind.
Last year, Hanford started moving radioactive waste from single-shelled tanks into double-shelled ones, which are supposedly safer. However, this turned out to be not as safe for the workers.
“When they move that waste, they have a lot more vapors coming out from the stacks. The wind was blowing toward me from that stack. That changed my life and hurt my lungs,” Seth Ellingsworth, who became seriously ill from the fumes, told RT. “It kept getting worse and worse.”
According to officials at Hanford, 42 workers were evaluated for vapor exposure after the leakage. In total, 31 people have reported symptoms, while 11 requested evaluations as a precaution. They have all been cleared to return to work, despite obvious health risks.
Despite the magnitude of the problem, the incident has largely gone unreported in the national media, leaving it up to local news outlets.
