Recently there have been warnings of the danger to the population as a whole resulting from the increased use of radioactive materials and of x-ray in diagnosis. However, physicians in general are not yet well enough informed as to the potential harm. In the words of the Handbook on X-ray Protection of the National Bureau of Standards,1 "with the increasing use of radiation and materials emitting radiation, it is necessary for the medical profession to exercise great caution and restraint in the use of X-rays for diagnosis and treatment of nonmalignant disease. Current methods and practices should be reviewed to see whether the same result could be obtained with less radiation."
To illustrate the extensive use of ionizing radiation in the United States, it was recently stated by Moeller and associates2 of the U. S. Public Health Service that there are 126,000 x-ray units for diagnosis and therapy
