The subatomic particle that carries a negative charge
What is an electron?
The overall darkness or blackness of the radiograph
What is density?
Radiation effects passed on to future generations
What are genetic?
Done before exposure of the pt. and can only be done by the dentist
What is proper prescribing of x-rays?
Film placed inside the mouth
What is intraoral film?
An unbalanced atom
What is an ion?
Controls the penetrating ability of the x-ray beam
What is kilovoltage?
Effects from small doses of radiation absorbed over a long period of time
What are long-term effects?
The time between exposure of radiation and clinical symptoms
What is the latent period?
The standard film
What is size 2?
When an electron is removed from an atom
What is ionization?
Milliamperage, Kilovoltage, Exposure time, and Distance all together in the same place
What is (intensity) of the beam?
Injury that takes place when x-ray energy is absorbed and the water within the cell is ionized
What is free radical formation?
Amount of aluminum filtration needed for machines that operate above 70 kvp
What is 2.5mm?
Film that is one-side, never exposed to radiation, and never removed from darkroom
What is duplicating film?
Radiation that exits the tubehead
What is primary radiation?
Reduces the intensity of the x-ray beam by half while increasing the penetrating ability (quality) of the x-ray beam
What is an aluminum filter (Half-value layer)?
Theory that purposes that the water within the cell absorbs the radiation energy and cause toxins to form
What is the indirect theory?
Operator's primary dictum (rule) for protection
What is avoid the primary beam?
Stops backscattered radiation and indicates whether film was placed backwards
What is the lead foil?
Converts electrons to radiation
What is the Anode?
The intensity of radiation is inversely affected by the distance that the radiation has to travel
What is inverse square law?
The most susceptible cell in the human body
What is the small lymphocyte?
Formula used to determine the amount of radiation an occupationally exposed person has accumulated
What is "age minus 18 times 5 rems per yr"?
Holds the latent image
What is emulsion/halide crystals?
