Answer to Question #14 Submitted to "Ask the Experts"

Category: Radiation Effects — Cancer and Leukemia Risks

The following question was answered by an expert in the appropriate field:

Have there ever been any studies correlating tumor induction in the extremities as a result of exposure to ionizing radiation (not including melanomas)?

Here is an answer to your question by Dr. Kenneth L. Mossman, Professor, Arizona State University:

"Muscle, bone, and connective tissues (e.g., cartilage) are relatively resistant to the carcinogenic effects of ionizing radiation. The induction of bone sarcomas is well known in humans and animals. Bone cancers (in the leg) have been known to occur in Ra dial painters as a consequence of ingesting large quantities of Ra salts. The work of Robley Evans is particularly noteworthy in documenting risks. Animal studies (e.g., dogs) also have documented bone cancer following radiation exposure. Extensive studies at the University of Utah, and the University of California-Davis have been conducted. Newell Stannard's excellent history of radioactivity provides a detailed description of these studies with ample references."

If you wish for more information or have a more specific question please get back in touch with us. The studies that Dr. Mossman refers to are rather high-dose studies. The book Dr. Mossman refers to is called Radioactivity and Health: A History. It was published by Pacific Northwest Laboratory.
