On January 16, 2007 the Journal News reported that four of twelve fish samples taken from the Hudson by Entergy showed detectable levels of strontium-90 in their flesh, raising new concerns as to the level of environmental damage caused by the leak of radioactive water containing strontium-90 from the Indian Point 1 spent fuel pool. Of the four showing higher levels, one was collected near Indian Point, and the other three near the Newburgh-Beacon bridge, about fifteen miles north of the plant. Riverkeeper immediately called on state and federal regulators to broaden their sampling program, so that a better picture of the extent of contamination could be ascertained. This toxic radionuclide, known as a “bone seeker” because it mimics calcium and concentrates in bone, can cause leukemia and bone cancer if ingested in high amounts. Despite Entergy’s claim to the contrary, Indian Point is known to be at least one source of strontium-90 in the Hudson, and the only one currently known to be discharging this toxic substance into the river. Low levels of strontium-90 remain in the global environment from nuclear weapons testing during the 1950s and 60s, and the Knolls Atomic Laboratory dumped radioactive waste into the Mohawk River near Schenectady during the same time period. The Mohawk is a tributary of the Hudson. Stay tuned for a more detailed update in the upcoming spring 2007 issue of Riverkeeper magazine.
