The EPA is not a medical agency and does not regulate the use of radiation in medical diagnosis and treatment. For more information, please visit the links below.
states
Individual states regulate the practice of medicine by licensing physicians. Qualified physicians and other specialized healthcare workers are permitted to use their professional experience and judgment when deciding how much radiation to use to diagnose or treat a patient. For that reason, the use of radiation for medical imaging is exempt from federal dose limits.
