Matter and Energy
This, by definition, is the ability to do work.
What is energy?
The definition of radiation is the transfer of this.
What is energy?
This scientist discovered x-rays in 1895.
Who is Wilhelm Roentgen?
This is the foundational radiation safety principle in x-ray imaging used to minimize exposure while maintaining high-quality images.
What is ALARA?
This is the kinetic energy released in matter and uses the SI unit Gya.
What is exposure or air kerma?
This term is described as anything the occupies space and has mass.
What is matter?
This is radiation that is capable of removing an orbital electron from the atom with which it interacts.
What is ionizing radiation?
The partially evacuated glass tube used in early experiments when x-rays were discovered is known as the:
What is the Crookes tube?
These are worn by radiographers and radiologists during fluoroscopy examinations to protect them from radiation exposure.
What are lead aprons?
This is the SI unit of the effective dose received by radiation workers and the population.
What is a sievert (Sv)?
Measured in kg, this is a primary distinguishing characteristic of matter.
What is mass?
Some examples of this type of radiation are cosmic rays and radon.
What is background radiation?
This well-known inventor developed the fluoroscope in 1898.
Who is Thomas Edison?
This restricts the useful x-ray beam to the part of the body to be imaged.
What is collimation?
This quantity refers to the radiation energy absorbed per unit mass and has the unit of Gyt.
What is absorbed dose?
This energy is the ability to do work by virtue of position.
What is potential energy?
This is the largest source of human-made radiation.
William Rollins was a dentist who first used these forms of beam restriction.
What are collimation and filtration?
This part of the x-ray room is located behind a lead-lined protective barrier and has a leaded glass window.
What is the control console?
This is the unit of quantity of radioactive material that was formerly known as the Curie (Ci).
What is the Becquerel?
This is most important type of energy that is used in x-ray imaging.
What is electromagnetic energy?
Visible light is radiated by the sun and is this type of radiation.
What is electromagnetic radiation?
This x-ray tube was developed in 1913 and is the precursor to the x-ray tubes still in use today.
What is the Coolidge tube?
These are the cardinal principles of radiation control.
What are time, distance, and shielding?
This is the customary unit of exposure that has a symbol of R.
What is the Roentgen?
