All the Polonium-210 in milk and groundwater.
A study released Friday by the US Geological Survey found the radioactive isotope in 24 private wells and one public well around Fallon, about 60 miles east of Reno. Polonium-210 is known to cause cancer in humans.
All dairies around Fallon sell their milk to the Dairy Farmers of America cooperative, which in turn markets the milk to a dairy in Reno and plants in northern California.
…Alexander Litvinenko, a former Russian security agent, was killed in London last year with a dose of polonium-210
The second in a series.
