As reported by Susan Smallheer at the Rutland Herald, the State of Vermont has detected radioactive, hazardous Strontium-90 in groundwater monitoring wells at Entergy's permanently shutdown Vermont Yankee atomic reator. State officials have indicated the Sr-90 almost certainly came from VY, and not atom bomb testing fallout. It very well could have come from the same leaks the contaminated soil and groundwater with tritium several years ago.
Sr-90 is a human bone seeker, and can cause bone cancer and leukemia, the article reports. This is shown on the graphic chart to the left (click here to see a bigger version).
