CONCORD, N.H. (AP) — New Hampshire health officials are testing fish in various parts of the state to see if there are elevated levels of radiation following a 2010 tritium leak at the Vermont Yankee nuclear plant.

The first tests done in May at Hermit Lake in Sanbornton found all 17 samples of largemouth bass were well below the FDA level of concern for consumption.

Additional samples were taken last month from fishing derbies in the following lakes: Winnipesaukee, Squam, Pleasant, Pawtuckaway, Opechee, and Northwood. The Connecticut and Nashua rivers also were sampled. Those results are pending.

The testing is to address concerns about Strontium-90 in fish following the tritium leak at plant in January 2010.

The chemical is a radioactive isotope. Vermont and Massachusetts also are testing.
