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