a. November 5, 1885
b. November 5, 1895
c. November 8, 1885
d. November 8, 1895 - Answers -d. November 8, 1895
Anode - Answers -Positive electrode
Cathode - Answers -Negative electrode
Photographic plates - Answers -exposed to x-rays created images
Early use of X-Rays could cause? - Answers -radiation burns and operator
electrocutions
X-rays were harmless as the scientific community initially thought. - Answers -False. X-
rays were quite harmful if exposed for long time
Treatment for radiation burns was amputation. - Answers -True
acute radiodermatitis - Answers -radiation burns
Clarence Dally - Answers -Assistant to Thomas Edison. First x-Ray fatality in the U.S.
Signs of a Rad Techs in the early days - Answers -Amputations and gloved hands
became identifying traits of the profession.
X-ray Dermatitis - Answers -Effects of Over exposure
fluoroscope apparatus - Answers -A device that allows dynamic x-ray examination
using x-rays and a fluorescent screen
ionizing radiation - Answers -radiation with sufficient energy to ionize atoms
Fundamental quantities - Answers -mass, length, time
derived quantities - Answers -acceleration, force, momentum, work, and power
, Radiologic quantities ( special Quantities ) - Answers -dose, dose equivalent, exposure,
and radioactivity
Forms of energy - Answers -These include electromagnetic (The one for Rad tech),
electrical, chemical, and thermal.
Potential energy is energy in a - Answers -stored state.
Kinetic energy is energy being expended - Answers -being expended
Inertia is the property of an - Answers -object with mass that resists a change in its
state of motion.
roentgen(R) British System; coulomb/kilogram (C/kg) Metric System - Answers -a
measure of the number of electrons liberated by ionization per kilogram of air.
radiation absorbed dose (rad) British Sys; gray ( Gy) Metric Sys - Answers -the unit for
absorbed dose.
radiation equivalent man (rem) British Sys: sievert (Sv) Metric Sys - Answers -is used
to quantify occupational exposure or dose equivalent.
curie (Ci) British Sys; Becquerel (Bq) Metric Sys - Answers -used to quantify
radioactivity.
Radiographic equipment may be classified as - Answers -mobile or permanently
installed
tube stand or tube mount - Answers -the portion of the tube head assembly that gives
mobility to the x-ray tube.
table - Answers -Needed to easily position patients for examination
Designed to raise and lower
Has a four-way floating top with electromagnetic locks
A variation is used with fluoroscopy equipment
Wall unit - Answers -It consists of a vertical rail assembly affixed to the wall and floor
and a vertical Bucky assembly.
The rail allows for adjustment of the height of the vertical Bucky.
The vertical Bucky is the same as the horizontal one in the table and serves the same
purpose.
The wall unit allows for easily obtained upright examination.
Control panel - Answers -Used by the radiographer to select the kilovoltage and
milliamperage that is applied to the x-ray tube to produce x-rays
