"My profession, which is in my soul, is to document things," says photographer Carole Gallagher. For seven years, she worked on American Ground Zero: The Secret Nuclear War, a book that documents the aftermath of nuclear testing in Utah and the West's "culture of cancer" through photography and oral history. In an upcoming Denver show and lecture, she will profile some of the West's downwinders, atomic veterans and test-site workers whose lives are plagued by illness. Her work has made friends in high places; until the Justice Department vetoed the idea, Gallagher says Energy Secretary Hazel O'Leary had planned to write the introduction for the book's paperback version. The exhibit, based on Gallagher's book, runs Feb. 10-March 16 at the University of Denver School of Art, 2121 E. Asbury St. On Feb. 9 at 6:45 p.m, the photograper will talk about her experiences compiling the book. For more information call the School of Art at 303/871-2846.
