Only hospitals in the United States that use radiation are required to have a medical radiation dose chart, states Diagnostic and Interventional Cardiology. However all qualified medical personnel are required to have access to updated training and safety material pertaining medical imaging devices that emit radiation, according to the FDA.
Medical imaging professionals who perform CT imaging are required to report and document the radiation dose administered to a patient in the diagnostic imaging report, according to Diagnostic and Interventional Cardiology. The Presidential Panel has recommended that such reporting be extended to x-rays and be documented in the patient's medical file, according to Harvard Health Publications.
The FDA also stipulates that all imaging equipment should be able to record the radiation dose for each patient and warn the operator if the optimum level is exceeded.
