Stack #4622218

QuestionAnswer
1.Ionizing Radiation Radiation containing positively and negatively charged ions when passed through matter
2.Negative effect of ionization in human cells ionization in human cells create unstable atoms, free radicles and new biological molecules that are detrimental to a living cell.
3.Exposure (Coulombs/kilogram) Measures the NUMBER of ionizations in air
4.Air KERMA (Joule/Kilogram) Measures the ENERGY of ionizations in air.
Absorbed Dose (Gy/mGy) -Tells use the absorbed energy plus short-term effects. -Result of photoelectric absorption & Compton scatter. -
6.Equivalent Dose (SV) -Used to compare biological damage from different radiation types. -Tells us Long-term effects -EqD=D*Wr
7.Effective Dose (SV) -Compares harm based on both radiation and tissue type. -EfD=D*Wr*Wt
8.Diagnostic Efficacy How useful and accurate an imaging exam is in helping the doctor make the correct diagnosis.
9.kVp kVp controls how strong and penetrating the x-ray beam is. mAs is like how much water comes out of a faucet, while kVp is the pressure that pushes the water through.
10.Primary radiation beam that comes out form the x-ray tube and towards the patient and receptor.
11.Attenuation Reduction in the number or intensity of x-ray photons as they pass through matter.
12.Early tissue reactions -Nausea -Fatigue -Diffuse redness of the skin -Loss of hair -Intestinal disorders -Fever -Blood disorders -Shedding of the outer layer of skin
13. Late tissue reactions -Cataract formation -Fibrosis -Organ atrophy -Loss of parenchymal cells -Reduced fertility -Sterility
14.Stochastic Effects -Cancer -Genetic effects
15.Dose Area Product (DAP) The total radiation dose delivered to a patient, including the size of the area exposed. (mGy·cm²)

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.
