ionization
Ans- the production of ions (an atom that gains or loses an electron and
becomes electrically unbalanced)
ion pair
Ans- when an electron is removed from an atom in the ionization process
1. the atom becomes the positive ion
,2. the ejected electron becomes the negative ion
ionizing radiation
Ans- radiation that is capable of producing ions by removing or adding an
electron to an atom; x-rays produce ionization
1. particulate radiation
2. electromagnetic radiation
particulate radiation
Ans- tiny particles of matter that possess mass and travel in straight lines at
high speeds
electrons
beta particles
cathode rays
protons
alpha particles
,neutrons
electromagnetic radiation
Ans- the propagation of wave-like energy (without mass, without particles)
through space or matter
cosmic rays
x-rays
microwaves, radio waves
gamma rays
ultraviolet rays
visible light
we want--short wavelength, high frequency
velocity
Ans- the speed of a wave
, wavelength
Ans- the distance between the crest of one wave to the crest of the next
wave
frequency
Ans- the number of wavelengths that pass a point in a certain amount of time
X-ray
Ans- electromagnetic ionizing radiation of VERY SHORT WAVELENGTH
resulting from the bombardment of tungsten by highly accelerated electrons in
a vaccum
properties of X-radiation
Ans- 1. x-rays have a wave form; xrays travel in waves with short wavelengths
and high frequency
2. x-rays travel at the speed of light (186,000 miles/second)
3. x-rays have the power to penetrate substances
