Introduction to Radiography

o The radiation are of higher energy (shorter wavelength) version of the electromagnetic waves

o Source – X ray/ Gamma ray

o X-rays are produced by an x-ray generator

o Gamma radiation is the product of radioactive atoms.

o X-rays and gamma rays can be characterized by frequency, wavelength, and velocity.
