JOHN W. GOFMAN, a professor emeritus of medical physics at the University of California at Berkeley, has long contended that there is no safe level of radiation exposure. “I concluded it’s impossible for such a level to exist given the evidence on how radiation works,” says Gofman. The term “low-level radiation” is a political term used by the nuclear industry to lull the public into accepting exposure risks, he says. Similar phrases also downplay the consequences. “The terms `tolerance level,’ `allowable level,’ `permissible dose’ — those are all phenomenal words that are supposed to tell Joe Six-Pack, `Nothing to worry about — there ain’t no harm.’ That’s why these terms came into existence,” he asserts.
The 79-year-old Gofman is in a unique position to advise on such matters because he is a physician and holds a doctorate in nuclear physical chemistry. His research at Berkeley during World War II attracted the attention of J. Robert Oppenheimer, lead scientist in the Manhattan Project. After working on the atomic bomb at Oppenheimer’s request, Gofman completed his medical studies. But in 1969, Gofman fell from grace with the atomic establishment when he challenged the “acceptable” levels of radiation exposure then allowed.
After being ostracized by the atomic establishment for years, Gofman’s scientific opinions have been widely accepted of late. In 1990, for instance, after years of debate by U.S. scientists, a report by the fifth conference on the Biological Effects of Ionizing Radiation (BEIR V) concluded that radiation effects are proportional to dose in all cases. More recently, says Gofman, “The United Nations Scientific Committee on the Effects of Atomic Radiation said that the weight of evidence comes down on the side of no safe level. And the British National Radiological Protection Board in 1995 published a document in which they have now said that there can be no safe dose.”
