Patrolled with Indian Point Policy Analyst Phillip Musegaas. We gathered clams from the bottom of the east end of Haverstraw Bay in a “practice run” to prepare for eventually having clams and other shellfish analyzed for radioactive contamination that may be a result of the leaks from Indian Point’s spent fuel pools. Radionuclides, particularly strontium-90, concentrate in the bones and shells of fish and shellfish. Several samples of Hudson River fish have already shown slightly elevated levels of strontium-90, but the results are inconclusive because of fish migration patterns. Sampling shellfish would provide a better picture of the leaks’ effects on the Hudson ecosystem. Testing clams for strontium-90 is especially critical because they are a major food source for Atlantic and Shortnose Sturgeon that winter in Haverstraw Bay.
