MID LONG QUIZ Flashcards
what kind of radiation is capable of having different masses and traveling at different speeds
particulate radiation
what kind of radiation, for all of its different types, travels at the same speed
electromagnetic radiation
during ionization, what usual subatomic particle moves when one is added or removed
electron
in practice, the most common radiation that we use is
ionizing radiation
particulate radiation travels differently because of varying masses and chargers. also, all can be used for practice of radiologic technology. tf
false
when a cell is exposed to radiation, 4 occurrences can happen. when the radiation is high enough, it would pass through the cell with little chance of absorption because the higher the energy of radiation, the stronger the penetrability. tf
true
all germ cells are considered radiosensitive because of characteristic of immaturity and undifferentiated. tf
true
all radiation exposure will have a random change of effect to a person regardless of how much dose was absorbed. tf
false
for therapeutics, high radiation dose is recommended to eliminate neoplastic cells. tf
true
which of the following cardinal principlesof radiation protection is the most effective
distanc
what kind of shield material is commonly used for personnel protection
lead
what kind of material is used to reduce radiation tremendously from passing through another room
concrete
what happens to energy as it travels through space
it weakens
what does ALARA mean
as low as reasonably achievable
it is polyenergetic, meaning it emts myltiple beams at the same time
xray
why is gammar ray also considered therapeutic
because of radiopharmaceutical drug
it comes directly from a source, such as a radioactive substance or an x-ray tube, without interactions with matter
primary radiation
it is primary radiation that interacted with a matter then hit a patient or machine that results in scattering of radiation
secondary radiation
it obstructs the area of interest from the left lobe of the lung, to compensate wee need to check on the other side/additional view or lateral side
cardio pacemaker
it is a device that changes an x-ray beam into a visible image
image receptor
if you ar exoected to be exposed to radiation within an are with less room, what is the best principle to practice for alara?
have the shortest radiation exposure
this occurs during non-ionizing raidation exposure
excitation
what characteristic of electromagnetic radiation is always constant to all of its kinds
velocity
what emr is also know as heat
infrared
what general source of radiation is most commonly produced and active
man made radiation
what is described when an energy absorbed from a matter would result in an effect regardless of how much radiation is received
non threshold
what is the best way to protect ourselves from radiation
distance
what is the most common emr present in households for signal distribution
microwaves
what makes particulate radiation different from electromagnetic radiation
particulate radiation has mass, has charge, and has different speed
what subatomic particles are always equal in numbeer
protons and electrons
when is the only time an image artifacts is acceptable for a trancribed report of an acquired image
when it is the patient’s life support
which cell effect is beneficial for cell recovery
cell recovery
which of the follwoing cell effects often lead to the change of the cell’s behavior completely
cell mutation
whoch of the following describes ALAEA being practiced for the patient
proper patient instruction, communication, and ucnerstanding
which of the following describes raidactivty of an atom to return to normal/relaxed state
the atom emits energy to return to a relaxed statee
which of the following electromagnetic radiation is captured for detecting fever
infrared
which of the following situations are true when energy travles through space
it weakens
which of the following will possibly occur when a person is exposed to radiation
nothing,
temporarily damage
permanenly damage
kill the cell
what does ALARA mean
as low as reasonably achievable
