Radbio Unit 1
Intro to Radiation Protection & Radiation Types, Sources, & Doses
Term | Definition |
---|---|
Ionization | The ability to produce electrically charged particles by removing orbital electrons from an atom |
Consequence of ionization | Creating free radicals who can create new biologic molecules detrimental to the living cell |
Property of x-rays | Unaffected by electric or magnetic fields and cannot be focused by a lens |
Team approach | When participants assume responsibility for their areas of expertise and emphasize communication when caring for a patient |
Radiation protection | Effective measures to safeguard patients, personnel, and the general public from unnecessary ionizing radiation exposure |
Exposure | The amount of ionizations produced in air |
Absorbed dose | The amount of energy deposited in ai material per unit of mass |
Equivalent dose | Takes into account the type of ionizing radiation that was absorbed |
Effective dose | The best overall measure of the biologic effects of ionizing radiation |
Diagnostic efficacy | Basis for determining whether an imaging procedure or practice is justified to reveal the presence or absence of disease |
Optimization for radiation protection (ORP) | Synonym for ALARA where all reasonable actions that will reduce dose to patients and personnel are employed |
Threshold | A dose level below which a person would have no chance of developing a disease |
Radiation Safety Officer (RSO) | Person directly responsible for the execution, enforcement, and maintenance of the ALARA program by hospital administration |
BERT Method | Explains radiation to the public by comparing the amount of radiation received to natural background radiation over a period of time |
Alliance for Radiation Safety in Pediatric Imaging | Organization that raises awareness for dose reduction pediatric-specified scan protocols in CT |
Image Gently pledge | Encourages annual staff communication and reviewing protocol recommendations and adjustments as well as openly communicating with parents |
Pause and Pulse | Promotes safe fluoro operations on pediatric patients by adjusting techniques and using the lowest pulse rate |
Image Wisely Campaign | Encourages lowering the amount of radiation used in all medically necessary imaging studies and eliminating unnecessary procedures for adults |
Radiation | The emission of energy in the form of electromagnetic waves or moving subatomic particles passing through space from one location to another |
