Tests Show Workers At Hanford Nuclear Facility Inhaled Radioactive Plutonium
An anonymous reader quotes a report from King 5, a local news station for Seattle, Washington: On June 8 approximately 350 Hanford workers were ordered to "take cover" after alarms designed to detect elevated levels of airborne radioactive contamination went off. It was quickly determined that radioactive particles had been swept out of a containment zone at the plutonium finishing plant (PFP) demolition site. The work is considered the most hazardous demolition project on the entire nuclear reservation. At the time Hanford officials called the safety measure "precautionary." Officials from the U.S. Dept. of Energy, which owns Hanford, and the contractor in charge of the demolition, CH2M Hill, downplayed the seriousness of the event with statements including, it appeared "workers were not at risk", "(the alarm went off) in an area where contamination is expected" and there was "no evidence radioactive particles had been inhaled" by anyone. The KING 5 Investigators have discovered those statements are incorrect. An internal CH2M Hill email sent to their employees on July 21 was obtained by KING. It states that 301 (test kits) have been issued to employees and of the first 65 workers tested, a "small number of employees" showed positive results for "internal exposures" (by radioactive plutonium). Sources tell KING the "small number of employees" is twelve. Twelve people out of 65 is 20 percent. Still outstanding are 236 tests. A communication specialist with CH2M Hill sent a statement that more positive results are expected. "We expect additional positive results because analytical tests like a bioassay can detect radiological contamination at levels far lower than what field monitoring can detect," said Destry Henderson of CH2M Hill Plateau Remediation Company.Read more of this story at Slashdot.
