Fuente, the state's chief radiation control officer, knew immediately it was important. "I saw the levels of radium in that stuff and I thought, oh man, this could be big," he said in an interview earlier this month. Though radioactive contamination in oil fields was known to the Government and some oil industry scientists since 1948, nothing had been done about the problem until Mr. Fuente alerted other states to his finding and began his own investigation in Mississippi.
