radiation risk diagnostic x-rays

The American public has been concerned with radiation safety as far back as the tragic story of the “Radium Girls,” female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint between 1917 and 1920. While there is substantial data demonstrating powerful carcinogenesis from high-dose radiation, e.g., an atomic bomb explosion, can small doses of radiation cause cancer? Some believe that they can.
