(1) This subchapter establishes standards for protection against radiation hazards. Except as otherwise specifically provided, this subchapter applies to all licensees or registrants. Nothing in this subchapter shall be interpreted as limiting the intentional exposure of patients to radiation for the purpose of medical diagnosis or therapy.
(2) In addition to complying with the requirements set forth in this subchapter, every reasonable effort should be made to maintain radiation exposures, and releases of radioactive material in effluents to unrestricted areas, as low as is reasonably achievable. The term "as low as is reasonably achievable" means as low as is reasonably achievable taking into account the state of technology, and the economics of improvements in relation to benefits to the public health and safety, and other societal and socioeconomic considerations, and in relation to the utilization of ionizing radiation in the public interest.
