Flashcards in Rad 3 Deck (40):
1

Two parts of an atom

Central nucleus and the orbiting electrons

2

negatively charged particles which have very little mass

electron

3

well-defined paths that electrons travel in

orbits or shells

4

production of ions or the process of converting an atom into ions

ionization

5

emission and propogation of energy through space or a substance in the form of waves or particles

radiation

6

the process by which certain unstable atoms or elements undergo spontaneous disintegration or decay in an effort to attain a more balanced nuclear state

radioactivity

7

radiation that is capable of producing ions by removing or adding an electron to an atom

ionizing radiation

8

tiny particles of matter that possess mass and travel in straight lines and at high speeds

particulate radiation

9

the propagation of wavelike energy through space or matter consists of manmade and naturally occurring forms of radiation, organized on the electromagnetic spectrum

electromagnetic radiation

10

the concept which characterizes electromagnetic radiations as discrete bundles of energy called photons or quanta (no mass, travel at speed of light, and move through space in a straight line)

particle concept

11

the concept where electromagnetic radiation as waves and focuses on the properties of velocity, wavelength, and frequency

wave concept

12

contains the indicator light, time, kilovoltage, milliamperage

control panel

13

suspends the X-ray tube head

extension arm

14

tightly sealed, heavy metal housing

tube head

15

surrounds the X-ray tube and transformers, protects tube and grounds high voltage components

metal housing

16

surrounds X-ray tube and transformers, prevents overheating and sparking

insulating oil

17

permis exit of x-rays from tube head, seals the oil and filters x-ray beam

tubehead seal

18

heart of generating system

X-ray tube/ glass vacuum tube

19

alters voltage of incoming electricity

transformer

20

filter out non penetrating longer wavelength x-rays

aluminum disks

21

restricts size of x-ray beam

lead collimator

22

aims and shapes the x-ray beam

PID

23

measures several inches long by 1 inch in diameter

a glass vacuum tube

24

what does the glass vacuum tube include

leaded-glass housing
cathode
anode

25

this prevents x-rays from escaping in all directions

leaded glass housing

26

part of leaded glass housing that permits the x-ray beam to exit the tube

the window

27

the negative electrode

cathode

28

what produces electrons necessary to generate x-rays

the cathode

29

the device that produces electrons when heated

tungsten filament

30

this focuses electrons in a narrow beam and directs the beams toward the tungsten target

molybdenum cup

31

the positive electrode

anode

32

converts electrons into x-ray photons

anode

33

what device is the anode

the tungsten target

34

measurement of the number of electrons moving through a conductor

amperage

35

measurement of electrical force that causes electrons to move from a negative to a positive pole

Volts

36

filament current that determines the number of e- in a current

mA or millamperage

37

tube current that controls the force that propels e-

kVp or kilovolts

38

amount of time x-rays are being produced

exposure time

39

bundles of energy/ x-rays

photons

40

a path of electrical current

circuit
