Priscilla Laws, author of "X-rays: More harm than good?" (Rodale Press, 1977) is interviewed by Lynn Samuels. She talks about the overuse (and misuse) of radiation in routine medical and dental procedures and urges people to learn as much as they can about it before consenting to X-ray exposure. She ties this into larger concerns about the structure of health care in the United States. Produced for WBAI by Lynn Samuels.
