RGD may be fixed or portable with any of the following characteristics: DHS 157.03(288m)(a)(a) Mobile-means RGD equipment mounted on a permanent base with wheels and/or casters for moving while completely assembled. DHS 157.03(288m)(c)(c) Stationary-means RGD equipment that is installed or placed in a fixed location. DHS 157.03(288m)(d)(d) Transportable-means RGD equipment to be installed in a vehicle or that may be readily disassembled for transport or use in a vehicle. DHS 157.03(289)(289) “Radiation head” means the structure from which the useful beam emerges. DHS 157.03(290)(290) “Radiation incident” means the loss of control of a radioactive source or materials or the unintended exposure of an individual to radiation that exceeds the limits in this chapter. DHS 157.03(291)(291) “Radiation installation” means any location or facility where radiation machines are used or where radioactive material is produced, transported, stored, disposed of or used for any purpose. DHS 157.03(292)(292) “Radiation machine” means any device capable of producing radiation, except those devices with radioactive material as the only source of radiation. DHS 157.03(293)(293) “Radiation room” means a shielded room in which irradiations take place. Underwater irradiators do not have radiation rooms. DHS 157.03(294)(294) “Radiation safety officer” or “RSO” means an individual who has the knowledge and training to apply appropriate radiation regulations and has been assigned the responsibility for the overall radiation safety program by the registrant or licensee and is identified on a registration or a specific license. DHS 157.03(295)(295) “Radiation safety officer for industrial radiography” means an individual with the responsibility for the overall radiation safety program for a licensee or registrant and who meets the requirements of s. DHS 157.44 (2). DHS 157.03(295m)(295m) “Radiation safety officer for medical use” means an individual that meets the requirements of s. DHS 157.61 (7) (a) or who is identified as a radiation safety officer on a department, NRC or another agreement state medical use license or other equivalent license or permit recognized by the department for similar types and uses of radioactive material. DHS 157.03(296)(296) “Radiation therapy simulation system” means a radiographic, CT or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field. DHS 157.03(297)(297) “Radioactive drug” means any chemical compound containing radioactive material that may be used on or administered to patients or human research subjects as an aid in the diagnosis, treatment or prevention of disease or other abnormal condition.
