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. DHS 157.03(298)(298) “Radioactive marker” means radioactive material placed in the well-bore or on a structure intended for subsurface use for the purpose of depth determination or direction orientation. DHS 157.03(299)(299) “Radioactive material” means any solid, liquid or gas that emits radiation spontaneously. DHS 157.03(300)(300) “Radioactivity” means the transformation of unstable atomic nuclei by the emission of radiation. DHS 157.03(301)(301) “Radiograph” means an image which is created directly or indirectly by radiation and results in a permanent record, either film or electronically stored image. DHS 157.03(302)(302) “Radiographer” means any individual who performs or who, in attendance at the site where the sources of radiation are being used, personally supervises industrial radiographic operations and who is responsible to the licensee or registrant for assuring compliance with the requirements of this chapter and the conditions of the license or registration.
