QuestionAnswer
Exposure (coulomb per kilogram-amount of radiation produced in air when ionizing radiation is present.
Absorbed dose milligray [mGy]-the amount of energy that is deposited in a material per unit mass of the material.
Effective dose millisievert [mSv] a quantity that is a measure of general harm in humans.
Diagnostic Efficacy The degree to which the diagnostic study accurately reveals the presence or absence of disease in the patient
BERT A method that can be used to improve understanding and reduce fear and anxiety for the patient.
Alliance for Radiation Safety in Pediatric Imaging Partnership of medical societies whose overall common purpose is to reduce the radiation dose for pediatric patients.
Image Wisely Campaign Created to address concerns about the increase of public exposure to ionizing radiation from medical imaging
NEXT Nationwide Evaluation of X-ray Trends (NEXT) project in place to provide data on the measurement of radiation of x-ray machines.
The electromagnetic wave Radio waves  Microwaves  Infrared  Visible light
Mechanical vibration of materials Ultrasound
Ultraviolet X-rays  Gamma rays
Ionizing radiation The amount of energy transferred to electrons by ionizing radiation is the basis of the concept of radiation dose
Nonionizing radiation ultraviolet radiation [energy less than 10 eV], visible light, infrared rays, microwaves, and radio waves) does not have sufficient kinetic energy to eject electrons from atoms
Alpha Particles Emitted from nuclei of very heavy elements such as uranium and plutonium during the process of radioactive decay
Beta Particles Identical to high-speed electrons except for their origin  8000 times lighter than alpha particles and have only one unit of electric charge (−1) as compared with the alpha’s two units of electric charge (+2).

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.
