what is x-ray radiation

Question 1

What is an x-ray ?

Answer 1

X rays are a form of EM Radiation

Question 2

give 3 examples of Electromagnetic waves which have higher frequencies but lower wavelengths

Answer 2

• ultraviolet
  -x-ray
• gamma ray

Question 3

give 3 examples of electromagnetic waves which have lower frequencies but higher wavelengths

Answer 3

• radio
• microwave
  -infrared

Question 4

draw and label where the crest and trough is on wave ?

Answer 4

see what is x-ray radiation file (7)

Question 5

What is Frequency ?

Answer 5

Rate at which wave oscillates

Question 6

what metric do we measure frequency ?

Answer 6

Hertz

Question 7

what does these symbols stand for:
v
c
f
Λ

Answer 7

v = velocity of the wave m/s
C = speed of light 299,792,458 m/s
f = frequency Hz
Λ = wavelength m

Question 8

equation for speed waves

Answer 8

v=f*Y(greek looking Y)

Question 9

equation for Energy of the photon

Answer 9

E=h*F

Question 10

What does each symbol mean in E=h*F

Answer 10

E = Energy of the photon J
h = Planks constant (6.626 x 10-34 J.s)
f = Frequency Hz

Question 11

what are 3 main equations ?

Answer 11

E=hF
v=fY(greek looking Y)
c=f*Y

Question 12

describe Transmission ?

Answer 12

X-Ray passes straight through the tissue without interacting with anything

Question 13

describe Absorption ?

Answer 13

-X-Ray passes though the tissue, interacts with an atom in the tissue
-ALL the X-Rays energy is given to the tissue
-The X-Ray no longer exists

Question 14

describe scattered ?

Answer 14

-X-Ray passes though the tissue, interacts with an atom in the tissue
-SOME of the X-Rays energy is given to the tissue
-The X-Ray continues on with the rest of it’s energy
-Scattered X-Ray
At a different angle to the incident photon

Question 15

what can affect absorption and transmission

Answer 15

tissue density and thickness

Question 16

describe Attenuation in term of x-ray beam ?

Answer 16

Attenuation is the reduction of the intensity of an x-ray beam as it traverses matter.
