INTRODUCTION OF RADIOLOGIC TECHNOLOGY
13
At the end of class
  • Students will understand the term radiologic
    technology.
  • Student will be familiar with the discovery of
    x-rays.
  • Student will understand the development of the
    profession of Radiologic Technology
  • Students will understand definitions of radiation
    and its correlation to the EMS.
  • Students will be able to define ionizations of
    atoms and relate it to ionizing radiation.
  • Student will be able to state the differences
    between man-made radiation and natural background
    radiation.

Preconceived Ideas regarding X-ray field
Introduction to RT
16
The Incredible Hulk was hit by a gamma bomb in
order to become the Hulk. Can this really
happen? Peter Parker was bit by a radioactive
spider and gains his spidey powers. Can this
really happen? Irradiated vegetables are
dangerous because they become radioactive. Is
this true? After the x-ray exposure, the
technologist must wait at least a minute before
entering room because the radiation is still
present. Cell phones give off radiation and can
cause cancer. Cockroaches can survive the
radiation from a nuclear blast and will take over
the world when it happens. Too much radiation
or too many x-rays will cause you to glow in the
dark. The x-ray program is easier than the
nursing program.

History of X-rays
Clarence Dally 1st fatality of cumulative dose of
radiation Multiple reports of eye damage due to
x-ray Multiple reports of skin erythema due to
x-ray exposure Has this changed?
21
Emergence of X-ray into a Medical Field
History of X-rays
  • 1st Rad Tech considered to be Edward Jerman
  • Founding of ASXT in 1920
  • Name change to ASRT in 1964 due to the
    proliferation of specialties
  • No longer tech trade but now a profession
  • Profession needs analytical thinking and problem
    solving skills

22
History of X-rays
23
Radiant Energy
24
Electromagnetic spectrum
Packet of energy that behaves like a particle
25
Inversely proportional
As wavelength gets shorter, frequency increases
As wavelength gets longer, frequency decreases

Ionizations
30
Neutral charge..equal number of positive
charges (protons) and negative charges( electrons
31
The atom on the right has a negative charge since
it has one more electron that it has protons.
