that need the radiologic technology profession for diagnosis and
treatment.

Answer 2

medical fields that need radiologic technologists

Question 3

usage of useful radiation

Answer 3

ionizing radiation
non-ionizing radiation

Question 4

usesage of useful radiation
ionizing radiation

Answer 4

x ray
gammar ray
electron
positron
(PEG X)

Question 5

usage of useful radiation
non-ionizing radiation

Answer 5

soudwave
radiofrequency

Question 6

why do we need to protect ourselves from radiation

Answer 6

Radiation effects can either produce a random or certain effect,
therefore radiation interaction must be as low as reasonably achievable.
This applies to all medical workers and patients.

Question 7

cardinal principles of radiation protection

Answer 7

minimized time
apply shielding
maximum distance
(MAM)

Question 8

exposed to radiation as fast as possible

Answer 8

minimized time

Question 9

apply shielding in between the source and to the subject

Answer 9

apply shielding

Question 10

be far from the source as energy decreases when it travels through space

Answer 10

maximum distance

Question 11

for patients, the shorter time to be exposed, the lower radiation to be transmitted/absorbed

Answer 11

time

Question 12

for medical professionals, as much as possible, avoid being exposed unless necessary but brief.

Answer 12

time

Question 13

this protection is useful mostly for patients who move involuntarily and have multiple procedures

Answer 13

time

Question 14

materials

Answer 14

shield
lead is useful for wearable protective equipment. concrete is useful for walls

Question 15

useful for wearable protective equipment

Answer 15

shield
lead

Question 16

is useful for walls

Answer 16

shield
concrete

Question 17

doing for unnecessary exposure to sensitive organs for both patients and professionals

Answer 17

shield

Question 18

useful mostly for procedures involving prolonged exposure for both patients and professionals

Answer 18

shield

Question 19

as energy travels farther, its strength decreases.

Answer 19

distance
importance

Question 20

doing for unnecessary exposure to people who don’t need a radiation exposure

Answer 20

distance

Question 21

useful mostly for relatives and professionals who don’t need to be exposed

Answer 21

distance

Question 22

patient facing the image

Answer 22

receptor (film

Question 23

patient facing the x-ray

Answer 23

tube (Source)

Question 24

application of alara

Answer 24

avoid repat of exposure as much as possible

use optimal exposure factors

in certain cases, the exposure time is reduced

proper instructions, communications, and understanding are vital

if not needed, radiation must be shielded or distant

Question 25

unwanted parts of the medical image resulting from error or parts not to be included in an image

Answer 25

image artifacts

Question 26

prevention of image artifacts

Answer 26

proper patient instructions and quality assurance and quality control

Question 27

what is acceptable image artifacts

Answer 27

only if it is part of the patient’s life support

Question 28

cardio pacemaker

Answer 28

acceptable image artifacts

Question 29

damaged image receptor artifact

Answer 29

idk

Question 30

metal artifact

Answer 30

idk
