Which of the following would be considered a characteristic of x-rays?
1. have no mass
2. are electrically neutral
3.travel in straight lines
all of the above (1, 2, and 3)
The oldest and largest radiologic science professional organization is the:
American Society of Radiologic Technologists (ASRT)
The organization that sets standards and prepares examinations necessary to
certify radiologic technologists and limited operators is the:
American Registry of Radiologic Technologists (ARRT)
The radiation that exits the opposite side of the patient to expose the image
receptor (IR) is called:
Remnant radiation
,The term used to describe radiation that is absorbed by matter is:
Attenuation
The "unseen" image that is contained in the image receptor (IR) before it is
processed is called the:
Latent image
The radiation that exits the body in all directions and causes unwanted exposure
on the image receptor (IR) as well as anyone who is in the room is called
__________ radiation.
Scattered
The radiation that exits the x-ray tube and travels in-air to the patient is called:
Primary
The boxlike device attached under the tube housing that allows the limited
operator to vary the size of the radiation field is called the:
Collimator
An invisible line in the center of the x-ray beam and perpendicular to the long
axis of the x-ray tube is called the:
Central Ray
An exposure time of 0.02 seconds is equal to how many milliseconds?
,20 msec
The number 9 squared is equal to:
81
The number 4 is the square root of:
16
When 62 kVp is increased by 30%, the result is approximately:
81
When the fraction 7/8 is converted to a decimal, the result is:
0.875
When 230% is expressed as a decimal, the result is:
2.3
A radiographic image is made using 500 mA, 0.1 sec., 80 kVp, and
48-inches SID. The value of the mAs for this exposure is
50 mAs
, X-rays have electromagnetic energy. The velocity (or speed) of this energy
travels at a speed of:
186,000 miles per second
The smallest possible unit of electromagnetic energy is the:
Photon
The electrical current flowing in an x-ray tube is measured in:
Milliamperes
The force or strength of the electron flow in an electrical current is measured in:
Kilovoltage
The device used to produce the high voltage needed for x-ray production is
called the:
Transformer
In radiology, 80,000 volts is converted to:
80 kVp
The target and the filament in the x-ray tube are made of:
Tungsten
