Rad Bio & Protection

TermDefinition
Proton A particle that is contained in the nucleus. A positively charge subatomic particle Attracted to negative charges Significantly contributes to the weight of the atom
Electron Negatively charged subatomic particle. Attracted to positive charges. Does not significantly contribute to the atoms weight. Subatomic particle that orbit the nucleus.
atomic number In reference to the atom, it's denoted by the letter 'Z' Is the same as the number of protons in an atom Is the smaller of the two numbers that describes the amount of subatomic particles
Mass number In reference to the atom, it's denoted by the letter 'A" Is the same as the number of protons and neutrons. Is the larger of the two numbers that describes the amount of subatomic particles.
Ionization This term is used to describe the type of radiation used in medical imaging. When an atom loses or gains an electron. When an atom changed from being neutral to being charged
Wilhelm Roentgen German physicist who died from intestinal carcinoma, likely from radiation effects. Person who earned the first Nobel Prize for Physics. German physicist who accidentally discovered x-rays.
Maximilian Sievert Scientist whose name is the same as the SI unit for effective dose. His name is the same as the unit that replace the old effective dose unit.
Time, Shielding and Distance Pertains to safe practices in medical imaging. These three principles are used to protect the patient as well workers. Known as the cardinal principles of radiation protection
Free radicals Formed by, sunlight exposure, radiation, poor diet, some medications. Unstable molecules or atoms with excessive or deficient number of electrons. Too many of these can result in a cascade event and cause cell damage. Reversed by antioxidants
Absorbed dose Amount of radiation deposited in tissue. Measured in rad/gray. Does take into account the effect on living tissue
Effective dose Pertains to the amount of dose that will cause tissue damage. Is measured in rem/sievert
SI units These units replace imperial counterparts. These units are used by most of the world As of 2020, not primarily used in the United States Example: kg, meter, liter, sivert
Imperial/old units These units are used by a minority of the world. As of 2020, these are primarily used in the United States. Examples: pounds, inches, feet, rem
Cation The charged atoms are attracted to negatively charged atoms Positively charged atoms. Positive ion
Anion These atoms are attracted to positively charged atoms. Negative atoms Negative ions
Marie Curie Eponymously named unit of radioactivity This person's surname is the old unit for radioactivity This person's last name was replaced by the SI unit for radioactivity.
Diagnostic image/Medical Imaging Branch of medicine that includes bone density, x-rays, CT scan, nuclear medicine. Branch of medicine that helps practitioners diagnose patient condition with imaging. Allows operators to analyze patient anatomy and physiology though imaging.

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.
