Radiographic Physics and Imaging Chapter Key Terms
A skin reddening and inflammation caused by prolonged exposure to ionizing radiation
A partial vacuum tube that produced an electron stream and was used to study cathode rays and led to the discovery of x-rays
cathode ray tube
The combinations of fundamental quantities to form velocity, acceleration, force, momentum, work, and power
A device that allows dynamic x-ray examination using x-rays and a fluorescent screen
The foundation units of measure of mass, length, and time
Radiation with sufficient energy to ionize atoms
Medical imaging equipment that is designed to be easily transportable and can be taken to the patient's bedside, the emergency department, surgery, or wherever it may be needed.
Medical imaging equipment that is fixed in place in a specially designed and shielded room
permanently installed equipment
The special radiologic science category of measure for dose, dose equivalent, exposure, and radioactivity.
the basic building block of matter composed of electrons, protons, and neutrons
the number of protons and neutrons an atom has in its nucleus
the number of protons and atom contains in its nucleus
a force of attraction that holds the nucleus of an atom together and holds the electrons in orbit around the nucleus. Also refers to the amount of energy necessary to split an atom.
the combination of elements in definite proportions.
An atomic bond in which an outermost electron from one atom begins to orgit the nucleus of another adjacent atom in addition to its original nucleus.
subatomic particle with one unit of negative electrical charge and a mass of 9.109 x 10-31 kg.
a defined energy level at a distance from the nucleus within which electrons orbit.
a substance that can not be broken down into simpler parts by ordinary chemical meansl
an atomic bond in which one atom gives up an electron and another atom takes the extra electron and the difference in their electrical charge attracts and bonds the two together.
fixed ratios of each type of constituent atom resulting i a predictable mass
subatomic particle with no electrical charge and a mass of 1.675 x 10-27 kg
the central core of an atom made up fundamentally of protons and neutrons.
subatomic particle with one unit of positive electrical charge
