In 1965, the Long Shot test exploded an 80 kiloton bomb. The $10 million test, the first one supervised by the Pentagon and not the AEC, was really a trial run for bigger things to come. But small as it was, there were immediate problems. Despite claims by the Pentagon that the test site would not leak, radioactive tritium and krypton-85 began to seep into freshwater lakes almost instantly. But evidence of radioactivity, collected by Defense Department scientists only three months after the test, was kept secret for five years.
