In his review of Denise Kiernan’s “The Girls of Atomic City” [Book World, April 28], Scott Martelle wrote that “only a handful of people at the top  knew what was really going on” at Oak Ridge, Tenn., where uranium was being processed to build the world’s first atomic bomb.

I knew, and I was only a lowly Army corporal studying electric engineering at City College of New York. Also in the know were my fellow Army students after they received a letter from an Army friend at Oak Ridge, revealing that a former CCNY student there had been burned in a radiation mishap. It was also common knowledge among us that the Manhattan Project had something to do with the processing of uranium.
