Radbio Unit 1

Intro to Radiation Protection & Radiation Types, Sources, & Doses

TermDefinition
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
