Ch. 1 Challenge Questions (Bushong)
The ability to do work or physically influence surroundings because of position, chemical
state, or nuclear state. – answer energy
Secondary quantities that are derived from a combination of one or more of the three
base quantities (e.g., volume, density, and velocity). - answer derived quantity
Any electromagnetic or particulate radiation that has sufficient energy to remove an
electron from an atom. - answerionizing radiation
1/1000 of a rad, where the rad (radiation absorbed dose) is 100 ergs of energy
absorbed per gram of tissue. - answerair karma
Approximately 300 mrad/yr. - answerthe average level of natural environmental
radiation
The first heated filament x-ray tube was developed by a physicist, William Coolidge, in
1913. - answerthe Coolidge tube
The production of continuous x-ray images in real time using a special x-ray imaging
system, the fluoroscope, with continuous low mA. The fluoroscope was first
demonstrated by Thomas Edison in 1898. - answerfluoroscopy
The rate of change of velocity (speed and/or direction) with time. - answeracceleration
the term applied to the chemistry of the body - answerbiochemistry
A phosphor that glows when excited with x-rays. This is the phosphor with which
Roentgen was experimenting when he discovered x-rays. - answerbarium
platinocyanide
Roentgen discovered x-rays in: - answer1895

The Snook transformer was developed in which year? - answer1907
The Coolidge hot-cathode x-ray tube is introduced in which year? - answer1913
Describe how weight is different from mass. - answerWeight is determined by the force
of gravity. Weight changes in value with position in a gravitational field such as that of
