Current through Register Vol. 24-14, July 15, 2024
"Department" means the department of health.
"High radiation area" means any area, accessible to
				  individuals, in which radiation levels could result in an individual receiving
				  a dose equivalent in excess of 1 mSv (100 mrem) in one hour at 30 centimeters
				  from any source of radiation or from any surface that the radiation penetrates.
				  For purposes of these regulations, rooms or areas in which diagnostic X-ray
				  systems are used for healing arts purposes are not considered high radiation
				  areas.
"Particle accelerator" means any machine capable of
				  accelerating electrons, protons, deuterons, or other charged particles in a
				  vacuum and of discharging the resultant particulate or other radiation into a
				  medium at energies usually in excess of 1 MeV.
"Qualified expert" means an individual who has demonstrated
				  to the satisfaction of the department that he or she is knowledgeable, trained,
				  and/or experienced to measure ionizing radiation, evaluate safety techniques,
				  and/or advise appropriately on matters of radiation protection. The department
				  reserves the right to recognize qualifications in specific areas of radiation
				  protection.
"Radiation machine" means any device capable of producing
				  ionizing radiation except those devices with radioactive materials as the only
				  source of radiation.
"Radiation safety committee" means a registrant-appointed
				  committee of at least three members to evaluate and approve all proposals for
				  research, diagnostic, and therapeutic use of a particle accelerator. Committee
				  members should include, at a minimum, persons with expertise related to the
				  intended use of the accelerator, and a person experienced in depth dose
				  calculations and radiation safety.
"Radiation safety officer" means a knowledgeable and
				  responsible person assigned by the registrant who provides radiation protection
				  expertise to facilities and users of radiation machines.
"Radioactive material" means any material that emits
				  radiation energy spontaneously. A machine that emits X rays is not considered a
				  radioactive material.
"Registrant" means an owner or controller of a radiation
				  machine who is responsible for the safe operation of the radiation
				  machine.
"Restricted area" means any area with limited access for the
				  purposes of protecting individuals from undue risks of radiation exposure. A
				  restricted area cannot be a residential area; a building may contain both
				  restricted areas and residential areas.
"Unrestricted area" means any area freely available to the
				  public, workers, or other persons; and where a person may receive less than 1
				  mSv (100 mrem) per year or be subject to any dose rate less than 20 MICROSv/hr
				  (2 mrem/hr).
