Narrator: This is Science Today. Electromagnetic fields, or EMFs, are most often in the news for their possible link to certain cancers. But Richard Luben, a professor of biomedical sciences at the University of California, Riverside, says EMFs do have good points in biology.
Luben: EMFs are used to stimulate the healing of bone fractures. At the moment people are working hard on trying to develop new applications of helping bones keep their density. Osteoporosis, which is a big health concern, may be treatable at least partly. And pain perception can be altered by EMF treatment, there's evidence that nerve healing may be influenced by EMF treatment.
Narrator: In such a medical setting, high doses of EMFs are given, but not enough to hurt anyone.
Luben: It's directed in such a way and it has the kinds of frequency and wave form characteristics that makes it a positive influence on health rather than a possible risk.
